Vehicle properties

Orders in RouteQ can be delivered by regular vehicles or couriers traveling on foot or by public transit. Vehicle and courier have a common set of properties.

The vehicles field is used in the request to determine the vehicle or courier.

Vehicle or courier ID

Each vehicle or courier must have a unique numeric or string ID set in the id field. IDs must be unique within a single service request. They will be used as the usernames of the couriers when exporting data to Track & Trace.

You can also specify the vehicle's or the courier's numeric or string ID from your tracking system in the ref field and the courier's mobile phone number in the phone field so that they can be contacted from Track & Trace.

Transportation method

When building routes, it is assumed by default that a courier uses a passenger car for delivery (load capacity less than 2.5 tons). To specify delivery on foot, by truck, or by public transit, use the vehicle.routing_mode parameter. If all couriers have the same delivery method, you can use the routing option options.routing_mode.

Possible values:

• driving: The default method, routing for vehicles whose load capacity is less than 2.5 tons.

• truck: Routing for trucks whose default load capacity starts at 2.5 tons. You can specify additional parameters in vehicle properties. When planning for this transportation method, the algorithm considers road signs with cargo vehicle restrictions and the Moscow cargo frame restrictions.

• walking: A pedestrian route. The route uses only roads that can be walked.

• transit: A route that includes traveling by public transit and walking from the public transit stop to the delivery location. The real public transit timetable isn't taken into account, but it's considered that:

  • Getting to the destination by public transit is possible.

  • The courier arrives at the stop and immediately gets into the transport.

For couriers who use bicycles or scooters, specify the transportation method as on foot (routing_mode = walking) and use the speed adjustment factor (travel_time_multiplier). We recommend personalizing adjustment factors for each individual courier. For example, using the Plan/Fact report, you can compare the actual delivery time for a courier on a bicycle or scooter with the planned walking time.

Example 1

The example below uses the transit transportation method for all couriers. As a result, couriers deliver orders using public transit with optimal order allocation.

Example 2

The example below uses the transit transportation method for one courier and the driving method for another courier. Orders are distributed among couriers so that the vehicle delivers to locations situated further away from public transit stops or from each other.

Vehicle or courier capacity

In RouteQ you can define the vehicle capacity in terms of the maximum weight or cargo the vehicle/courier can transport over a single route.

To determine the vehicle or courier carrying capacity, use the capacity field (you can specify just one option):

• capacity.units: Number of units (pallets, boxes, kegs).

• capacity.weight_kg: Weight in kilograms or bulk weight.

• capacity.volume: The volume, which is measured in cubic meters and set as the product of dimensions:

  • capacity.volume.width_m: Width in meters.

  • capacity.volume.depth_m: Depth in meters.

  • capacity.volume.height_m: Height in meters.

  If values are unknown, use capacity.volume_cbm.

• capacity.volume_cbm: Volume in cubic meters.

If the vehicle has both size and volume specified, capacity.volume defines the dimensions and capacity.volume_cbm defines the carrying capacity.

For more information about weight determination, see Weight and volume.

Additionally, you can set the maximum load of a vehicle as a percentage of the specified load capacity. To do this, use the limits request field:

• limits.volume_perc: A percentage of the value specified in capacity.volume.width_m * capacity.volume.depth_m * capacity.volume.height_m.

• limits.weight_perc: A percentage of the value specified in capacity.weight_kg.

• limits.volume_perc: A percentage of the value specified in capacity.volume.

To indicate that overload is allowed relative to a given value, specify a value greater than 100. To leave spare load capacity, for example, to allow for the inaccurate estimation of order dimensions, specify a value less than 100. For example, a value of 110 allows for 10% overload and a value of 90 allows for a maximum load of 90% of the specified load capacity.

The vehicle capacity (based on the limits) is a hard restriction that won't be violated. Note that, when calculating the vehicle load, the system takes into account the orders for pickup and delivery. For more information, see Pickup and delivery.

Example

There are two vehicles with a load capacity of 1.5 tons (Vehicle 1) and 3 tons (Vehicle 2) and three orders for delivery with a weight of 1 ton, 1.2 tons, and 1.4 tons, respectively.

When optimizing routes, the 1.2-ton order is placed in Vehicle 1 and the 1-ton and 1.4-ton orders are placed in Vehicle 2.

Custom capacity units

A custom unit restricts the capacity of the vehicle according to the custom unit of measurement specified for orders.

You can set several custom capacity units for vehicles. Each of them should have its own ordinal number N (numbering starts from 0). Each unit is described by two parameters:

• capacity.custom.N.name: Name of the custom unit.

• capacity.custom.N.size: Vehicle capacity in custom units.

By default, the capacity is not limited by the parameter capacity.custom.N.size.

Example of filling in Excel file sheets for a custom price parameter (order cost):

Example 1.1

4 vehicles deliver 16 orders. Weight, volume, and load capacity (number of units) are specified for the vehicles. Custom units have been set for orders (to limit the cost, location.shipment_size.custom.0) and for the vehicles (to limit the total cost of transported orders, vehicle.capacity.custom.0).

There are 2 vehicles transporting 1 order each. However, their weight, volume, and number of units is small, because the order cost is approaching the vehicle's limit.

API request (JSON) ⋅ API response ⋅ View on map

Example 1.2

The same as example 1.1, but the maximum number of orders that the vehicle can transport is also specified. The restriction is set using the location.shipment_size.custom.1 and vehicle.capacity.custom.1 parameters. Each vehicle can now carry no more than 5 orders.

The number of orders in three vehicles has changed. Now one vehicle carries one order, and orders cannot be added due to the total cost limit. For the rest, maximum utilization by total cost in each vehicle was achieved, and it was possible to maintain the limit on the number of orders.

API request (JSON) ⋅ API response ⋅ View on map

Example 2

Two vehicles deliver 20 orders. Orders have different lengths. This property is described by two custom units:

• Unit Length5 (location.shipment_size.custom.0) is 1 for orders with a length of 5 meters (these are orders from 10 to 15) and 0 for all other orders.
• Unit Length6 (location.shipment_size.custom.1) is 1 for orders with a length of 6 meters (these are orders from 16 to 20) and 0 for all other orders. Orders from 1 to 9 have a length of less than 5 meters. For them, both custom units Length5 and Length6 are 0.

Vehicles have the same load capacity, but different body lengths:

• Vehicle6 has a body length of 6 meters and can transport any orders. For this vehicle, vehicle.capacity.custom.0 and vehicle.capacity.custom.1 are both 10 (taking into account the weight of the orders and the vehicle's load capacity).
• Vehicle5 has a body length of 5 meters and can't transport orders with a length of 6 meters. For this vehicle, vehicle.capacity.custom.0 = 10, while vehicle.capacity.custom.1 = 0.

In the planned solution, Vehicle5 transports orders that are 5 meters long or less, while Vehicle6 transports orders that are 6 meters long, 5 meters long, or less than 5 meters long.

Minimum order weight for a vehicle

To prevent a heavy truck from carrying a single small order across town, use the min_stop_weight parameter. Using this parameter, you can specify the minimum total weight that a vehicle will deliver to a single location. This is relevant when planning freight transportation by vehicles of different capacity.

The restriction is soft: the algorithm may violate it. Penalties are set in the fields:

• penalty.min_stop_weight.fixed: A penalty for violating the minimum total weight for all orders in a single location (1000 by default).

• penalty.min_stop_weight.kg: A penalty for each kilogram that the total order weight delivered to a single location (50 by default) is short.

For more information about using vehicles with different capacity, see Transport with different load capacities.

Example 1

Two vehicles with capacities of 1500 and 10,000 kg are delivering orders weighing 100, 500, 900, and 9000 kg. The large truck gets both light and heavy orders.

API request (JSON) ⋅ API response ⋅ View on map

Example 2

For a vehicle with a capacity of 10,000 kg, the specified value of min_stop_weight is 1000. As a result, the larger vehicle only gets the order weighing 9000 kg.

API request (JSON) ⋅ API response ⋅ View on map

Vehicle properties

You can specify vehicle properties in the vehicle.specs field. The following parameters can be specified:

• width: Vehicle width in meters.

• height: Vehicle height in meters.

• length: Vehicle length in meters.

• max_weight: Maximum vehicle weight in tons.

• max_weight_kg: Maximum vehicle weight in kilograms (rounded up to the ton when addressing the planning task).

• axle_weight: Maximum load on a vehicle axle in tons.

The minimum value is 0 for all the listed properties.

Load handling time at depot

The loading or unloading time at the depot may depend both on orders and vehicle properties (for example, dimensions or equipment).

To specify the amount of additional time required for loading at the depot, use the vehicle.depot_extra_service_duration_s parameter. The time is set in seconds.

Example

2 vehicles with the same load capacity are delivering 13 large orders. The handling time at the depot depot.service_duration_s is 5 minutes (300 seconds). Additional time is set for loading orders into a vehicle at the depot vehicle.depot_extra_service_duration_s: 30 minutes (1800 seconds). As a result of planning, each vehicle will spend 35 minutes at the depot before starting their routes.

API request (JSON) ⋅ API response ⋅ View on map

Start of a loaded vehicle

If a vehicle is loaded in advance and there is no need to spend time loading it at the beginning of the shift, use the starts_loaded = true vehicle property. The handling time before the first run will then be ignored for this vehicle during route planning.

Example

Two vehicles deliver orders: the first one is loaded in advance, and the second one has to be loaded at the start of the shift. The handling time depot.service_duration_s is 10 minutes (600 seconds).

As a result of planning, the first vehicle will immediately start the route, and the second vehicle will spend 10 minutes at the depot before departing.

Vehicle started not from the depot

By default, vehicles and couriers start from the depot. However, sometimes they need to start the route from another point (for example, from their home or parking spot). That's a usual task in the case of sales representatives, service engineers, and other specialists who don't deliver goods, but provide services.

You can implement this requirement using the property vehicle.start_at. In this case, the courier or vehicle will start their route from the specified point with the type garage, rather than from the depot.

Visiting the depot before the start of the working day

At the beginning of the working day, couriers may need to visit the depot to get their orders there. Use the property vehicle.visit_depot_at_start to enable this. If you specify true, the courier or the vehicle must visit the depot before starting the delivery (this is default behavior). Otherwise, they can immediately start delivering orders. For more information, see Start or end of the route at an arbitrary point.

If couriers start from a garage location, but they need to pick up some orders at the depot, enable the option Can visit the depot at the beginning of the route (can_visit_depot_at_start in the API, false by default). This option only works for couriers that have the parameter visit_depot_at_start = false. For orders that need to be picked up from a depot, specify one of the following parameters:

— depot_id to link the order to a depot.

— depot_ready_time, the time when the order is ready at the depot.

— depot_expiring_time, the deadline for picking up the order from the depot.

You can also implicitly allow couriers to visit the depot at the beginning of the route with the can_visit_depot_at_start option disabled by explicitly specifying the depot in planned_route, fixed part of the route, or during additional planning.

Example 1

Three vehicles deliver orders: The first one starts the delivery from the depot. The second one starts and ends the route without visiting the depot. The starting point for the courier is order 6, which has the garage type. The third one starts the route not from the depot, but from order 4 (the garage type), but must visit the depot before starting the delivery.

Example 2

Three vehicles deliver orders: The first one starts the delivery from the depot. The second and the third vehicles start and end the route without visiting the depot. Orders 1 and 7 have the pickup type, and the algorithm selects them as the first route points.

Three separate routes are planned in the solution because of the orders' priorities.

Example 3

Two vehicles deliver orders (visit_depot_at_start = false and can_visit_depot_at_start = true). The first one starts from a garage location and visits the depot to pick up order 1 at the beginning of the route. The second vehicle's route doesn't include a visit to the depot, it goes straight to the delivery.

Making stops at multiple depots

Couriers can stop at multiple depots along their routes. This is helpful when items are stored in different depots or when the route needs to end at a specific depot.

Specify depots using one of these methods:

1. On the Vehicles sheet in the Depots that the courier can visit field (vehicle.depot_id in the API), you can specify the depots that the courier is allowed to visit while following the route. They have a higher priority, so the algorithm can assign them as start, intermediate, or end depots.
2. In the fields:

• Depots to start from (vehicle.starting_depot_id in the API): The depots where the courier starts their route.
• Depots for additional loading (vehicle.middle_depot_id in the API): The intermediate depots to pick up additional orders along the route.
• Depots to end the route at (vehicle.ending_depot_id in the API): The depots where the courier completes the route.

Example 1

There are 9 orders in the planning task. Three depots are specified on the Vehicles sheet in the depot_id field: Depot 1, Depot 2, and Depot 3. The courier is allowed to stop at multiple depots along the route.

As a result of planning, the courier:

• Starts the route from Depot 2, because it is located next to the first order location.
• Ends the route at Depot 3, because the last order location is next to it.

API request (JSON) ⋅ API response ⋅ View on map

Example 2

The courier must deliver 9 orders. Planning involves 2 depots:

• Depot 2: a start (starting_depot_id = 2) and end (ending_depot_id = 2) depot.
• Depot 1: an intermediate depot (middle_depot_id = 1).

As a result of planning, the courier starts the route at Depot 2 and delivers 4 orders. Then the courier stops at Depot 1 for reloading, delivers the remaining orders, and ends the route at Depot 2.

API request (JSON) ⋅ API response ⋅ View on map

Example 3

The courier must deliver 9 orders. Planning involves 3 depots:

• Depot 1: a start depot (starting_depot_id = 1).
• Depot 2: an intermediate depot (middle_depot_id = 2).
• Depot 3: an end depot (ending_depot_id = 3).

The courier is allowed to visit the intermediate depot for reloading at the beginning of the route only (vehicle.depots_only_at_run_beginning = true). As a result of planning, the courier starts from Depot 1, then stops at Depot 2 for reloading, and starts delivering orders. Ends the route at Depot 3.

API request (JSON) ⋅ API response ⋅ View on map

Start from one of several depots

To allow the courier to start from one of multiple depots, list them in the Depots that the courier can visit (vehicle.depot_id in the API) or Depots to start from field (vehicle.starting_depot_id in the API). If there are several depots, the algorithm will choose the optimal depot to start from. If the fields depot_id and starting_depot_id are not entered for a courier, they start from the first depot in the depots list.

If you use the delivery from one of several depots functionality, a courier will be able to pick up orders from any depot they can visit.

For the courier, you can also set the parameters Allowed to visit multiple depots in one route (vehicle.allow_different_depots_in_route in the API) and Maximum number of depots for additional loading in one route (vehicle.max_middle_depots in the API). For more information, see Choosing the optimal depot to start from.

Additional loading at an intermediate depot

For the courier to be able to visit additional depots for reloading along the route, set the Allowed to visit multiple depots in one route (vehicle.allow_different_depots_in_route in the API) parameter to true. Specify depots for reloading in the field Depots that the courier can visit (vehicle.depot_id in the API) or Intermediate depots (vehicle.middle_depot_id in the API). If there are orders in several depots, the algorithm will select the optimal depot for reloading.

If the courier can stop at intermediate depots for additional loading at the beginning of the route only (before completing the first order), set the vehicle.depots_only_at_run_beginning parameter to true (by default, it's set to false).

For the courier, you can also set the Maximum number of depots for additional loading in one route parameter (vehicle.max_middle_depots in the API). For more information, see Visiting an additional depot.

Returning to a depot at the end of the route or run

By default, the courier completes the route at the depot where they started. To allow the courier to stop at multiple depots along the route, set the Allowed to visit multiple depots in one route parameter (vehicle.allow_different_depots_in_route in the API) to true. In this case, the courier can end the route at a depot other than the first one.

Specify the depots where the courier can complete the route in the Depots that the courier can visit (vehicle.depot_id in the API) or Depots to end the route at field (vehicle.ending_depot_id in the API). If there are several depots, the algorithm will choose the optimal depot to complete the route at.

If you want the courier to end the route at the same depot where they started it, set the vehicle.finish_route_in_starting_depot parameter to true (by default, it's set to false). In this case, if the courier's starting location is not a depot (vehicle.visit_depot_at_start = false), they will need to return to the depot where they started the second run of the route.

If you want the courier to end each run at the same depot where it was started, set the vehicle.finish_run_in_starting_depot parameter to true (by default, it's set to false). To allow the courier to change depots between runs, set the vehicle.can_change_depot_between_runs parameter to true. For more information, see Start of a new run from a different depot.

If the courier doesn't have to return to the depot after completing all orders, set Return to depot at the end of the shift (vehicle.return_to_depot in the API) to false.

Example 1.1

Two couriers are to deliver two orders: one is a delivery order that needs to be picked up from Depot 1, and the other one is a pickup order to be delivered to Depot 2. The couriers can only make 1 run each, starting at any depot and ending the route at any depot. Both couriers are allowed to stop at different depots during one run, but they cannot stop at intermediate depots.

The solution uses only one courier: they leave Depot 1 after picking up the delivery order, deliver it, pick up the pickup order, and deliver it to Depot 2, where they end the route.

Example 1.2

The same as in example 1.1, but the couriers need to end routes at the same depot where they started them (vehicle.finish_route_in_starting_depot = true).

The solution uses both couriers. Courier 1 leaves Depot 1 after picking up the delivery order, delivers it, and returns to Depot 1. The second courier leaves Depot 2, picks up the pickup order, and returns with it to Depot 2.

Return to any location at the end of the route

If your work scenario needs to take into account the distance of the last order from the courier's parking spot (or home address, for example), you can implement it as follows:

• Create a point with the garage type (the locations.type field). This point will only be used to end the routes.

• For a courier who needs to return home or to the parking spot at the end of their working day, enter the ID of this point in the vehicle.finish_at field.

In the solution, all vehicles or couriers that have the finish_atproperty specified return to the specified point. If the option to return to the depot is enabled (vehicle.return_to_depot = true), the route will first go the depot and then to the parking spot.

Example

The example below uses two vehicles with different load capacities and four orders with different weights. Two vehicles are used for delivery because of the weight restrictions. Vehicle 2 doesn't have to return to the depot after it delivers the last order.

API request (JSON) ⋅ API response ⋅ View on map

Start or end of the route as close to the depot as possible

You can plan a route so that the courier starts or finishes on the order that is closest to or furthest from the depot. For example, if you expect to get new orders in the morning, then it would be better to start the route with the orders closest to the depot. That way, it will be easier for the courier to return to the depot to pick them up. On the other hand, by starting the route with the farthest order, the courier would finish closer to the depot in the evening.

If you are not using advanced cost settings, set the following parameters:

• first_edges_penalty_factor: A penalty for the distance from the depot to the first order, the default is 0. If the value is greater than 0, the algorithm minimizes this distance, and if the value is less than 0, it maximizes the distance.

• last_edges_penalty_factor: A penalty for the distance from the depot to the last order, the default is 0. If the value is greater than 0, the algorithm minimizes this distance, and if the value is less than 0, it maximizes the distance.

Penalties are calculated similarly to the duration and length of route segments (see the Travel between route points group under Advanced cost settings).

If penalty values are high, routes may be suboptimal in terms of mileage. If penalty values are low, then the first or last order of a route may be selected in violation of any requirements provided it saves on mileage.

If you use advanced cost settings, use the keywords from the Travel from or to the depot group.

Example

In the example below, there is 1 courier and 10 orders. Two penalties are set: first_edges_penalty_factor = 2 and last_edges_penalty_factor = -2. Planning produces a route that begins with the order closest to the depot and ends with the furthest order.

Multiple courier runs per day

By default, a courier starts and ends their route at a depot, that is they complete exactly one route during a working day (shift).

If a courier can return to the depot anytime during the work shift to reload additional orders, you can limit the number of runs using one of the parameters:

• vehicle.shifts.N.max_runs: The maximum number of runs per shift. The default is 1.

• vehicle.max_runs: The maximum number of runs for all the courier's shifts summed up (for example, the courier can perform all the runs in one shift). The number of courier runs can be lower than the number of shifts. The default is 1.

• If none of the parameters are specified, the courier can make as many runs as they have shifts (one run per shift).

Example

The example below uses one vehicle with the limited carrying capacity of 2 tons and three orders with a weight of 0.8 tons. The vehicle is allowed to do two runs. This means that after completing two orders, the vehicle can return to the depot to pick up and deliver another order.

API request (JSON) ⋅ API response ⋅ View on map

Break before the last run

The break is set using the vehicle.extra_wait_before_last_run_s object. Mind the following:

• The break is scheduled before the last run in the shift.

• The start of the last run is shifted by the specified break time.

Example

A courier has two scheduled runs. A one-hour break and a 45-minute break are scheduled between these runs (extra_wait_before_last_run_s = 2700).

As a result, two breaks are scheduled:

• 60 minutes in the first run.
• 45 minutes before the start of the second run. As a result, the second run starts 45 minutes later.

API request (JSON) ⋅ API response ⋅ View on map

Limit the number of stops per shift

When planning a route, you can specify the minimum and maximum number of stops in the route. This can be useful, for example, to limit the maximum courier workload per day or, on the contrary, make sure that the courier gets on the route with a certain minimum number of stops.

For this, RouteQ uses the minimal_stops and maximal_stops shift parameters. You can set the number of stops for each courier.

The restriction is not strict and may be violated. If the limit on the minimum number of stops is violated, a penalty applies. The penalty is specified in the following shift fields: penalty.stop_lack.fixed (for making fewer stops than the minimum number) and penalty.stop_lack.per_stop (for each stop missing under the minimum number).

In the same way, if the limit on the maximum number of stops is violated, a penalty applies. The penalty is specified in the following shift fields: penalty.stop_excess.fixed (for making more stops than the maximum number) and penalty.stop_excess.per_stop (for each stop above the maximum number).

Unique stops

When using the minimal_stops parameter, orders with matching coordinates are considered different stops if they aren't consecutive in the route. For the minimal_stops condition to be fulfilled, the algorithm may plan the route to have the courier visit the same address multiple times.

To avoid repeat visits, use the minimal_unique_stops parameter and penalty.unique_stop_lack.fixed and penalty.unique_stop_lack.per_stop penalties instead of minimal_stops.

The minimal_unique_stops parameter considers only orders with unique coordinates, so there won't be any repeat visits planned for the courier. However, orders to the same address may be assigned to different couriers, because such stops are considered different in this case, and the algorithm can use this to enforce the minimal_unique_stops limit.

It makes sense to use the minimal_unique_stops limit if the route has a lot of multi-orders.

Stops for non-active couriers

By default, the minimal_stops and minimal_unique_stops limits apply to all assigned couriers. When you specify more couriers than necessary, and the penalty.stop_lack or penalty.unique_stop_lack penalty value is too high, this can result in suboptimal planning.

To set the minimum number of stops in a shift and build an effective route at the same time, use the option ignore_min_stops_for_unused (see Counting the minimum number of stops for active vehicles only).

Example 1

In the example, the route is built for 3 couriers who deliver to 15 points. Since there are no restrictions for the route, the route is built the usual way.

Example 2

This example has the same conditions as example 1, but sets the limit of 4 minimum stops per courier. As a result, the routes changed so that each courier visited at least 4 delivery locations.

API request (JSON) ⋅ API response ⋅ View on map

Example 3

This example has the same conditions as example 1, but sets the limit of 5 maximum stops per courier. As a result, orders are distributed evenly among all couriers, even though several orders are located next to each other and can be completed by one courier.

API request (JSON) ⋅ API response ⋅ View on map

Maximum shift duration

Sometimes you may need to extend the courier's working hours. But you also need to limit the maximum shift length and set the window you want to fit into. For example, there's a specific 14-hour time window during which couriers can make deliveries: from 8:00 to 22:00. However, the duration of each courier's shift must not exceed 10 hours (max_duration_s), and there should be no more than 8 working hours per shift (max_working_duration_s).

RouteQ helps you schedule shifts with hard time windows and preferred lengths. In this case, the courier's shift length doesn't affect the work start time. It only affects the time that they spend completing orders.

The maximum shift length can be set as a soft restriction shifts.N.max_duration_s that can be violated for a penalty or as a hard restriction shifts.N.hard_max_duration_s that can't be violated:

• When planning with a soft restriction, the workload that doesn't fit into one courier's preferred shift is distributed among others or to the same courier, but with penalties for violating the shift length. All orders that can't be completed in max_duration_s are added to the route with the penalty specified in the shift.penalty.late field (if applicable) or in the shift.penalty.out_of_time field all other times. The total route penalty for violating the maximum shift length is shown in the API response in the overtime_penalty field. If the estimated order cost including penalties is higher than the cost of completing the order by another courier, the order is handed over to another courier.

• When planning with a hard restriction, the courier's shift never exceeds the hard_max_duration_s value.

The maximum working time per shift can also be defined by a soft restriction shifts.N.max_working_duration_s or hard restriction shifts.N.hard_max_working_duration_s.

• If the courier violates a soft restriction, the workload is redistributed to other couriers or given back to the same courier, but with penalties. Orders that are not completed within the shift's working time max_working_duration_s will be added to the route with a penalty working_overtime:

  • shifts.N.penalty.working_overtime.fixed: Penalty for exceeding the maximum working time per shift.

  • shifts.N.penalty.working_overtime.minute: Penalty for each minute of such overtime.

  If the penalty value isn't specified, the penalty for violating the time window shift.penalty.out_of_time will be applied to the orders. You can find the total penalty amount in the working_overtime_penalty field of the API response. The order will be transferred to another courier if the estimated cost of the order (including penalties) exceeds the cost of completing the order with another courier.

• When planning with a hard restriction, the maximum duration of working time per shift never exceeds the value specified in hard_max_working_duration_s.

If you use both soft and hard restrictions for max_duration_s and max_working_duration_s, the hard one can't be lower than the soft one. By default, max_duration_s and max_working_duration_s are set to 2 days, while hard_max_duration_s and hard_max_working_duration_s are set to 30 days.

Example 1

Let's say the shift window shifts.N.time_window is from 8:00 to 23:00. By default, routes will be built to use the minimum number of couriers.

If you specify max_duration_s = 14400, the load is distributed between couriers, and each of them works for approximately 4 hours (the shift length is set in seconds). Some couriers may still work more than 4 hours, because it's less costly to pay for extra hours than to hand over the order to another courier.

As a result of planning, orders are distributed among three couriers. One courier's shift went over 4 hours. The penalty amount is shown in the API response in the overtime_penalty field.

Example 2

The same as in Example 1, but with hard restrictions on the maximum shift length: hard_max_duration_s = 14400. When planning, all couriers are given shifts that are 4 hours or less. As a result, the number of couriers increased to 4.

Example 3

Three couriers are delivering 26 orders. The shift window shifts.N.time_window is 8:00 to 23:00. Penalties are set for exceeding the maximum working time per shift: shifts.N.penalty.working_overtime.fixed for overtime, and shifts.N.penalty.working_overtime.minute for overtime per minute.

If you specify shifts.0.max_working_duration_s = 14,400, each courier will work for approximately 4 hours. The restriction is soft, and one courier worked overtime.

As a result of the planning, all orders are distributed among couriers, and the total penalty amount for overtime is indicated in the field working_overtime_penalty of the API response.

Maximum mileage per shift

In some cases, you need to limit the mileage per vehicle. For example:

• The planning includes hired cars, and their rate implies limited mileage.

• You can assign specific vehicles for far-away points. Then you can limit the mileage for other vehicles.

The shifts.max_mileage_km parameter determines the maximum vehicle mileage per shift. The entire mileage is taken into account, including:

• Traveling from the depot or starting point to the first point from the order list.

• Returning to the depot or end point of the route from the last point in the order list.

The restriction is soft: the algorithm may violate it. Penalties are set in the fields:

• shifts.penalty.max_mileage.fixed: A fixed penalty for exceeding the maximum mileage (1000 by default).

• shifts.penalty.max_mileage.km: A penalty per each kilometer in excess of the maximum mileage (100 by default).

If the maximum mileage per run is critical to you, and the vehicle can do several runs per shift, you can create multiple identical shifts (see Example 2).

If the courier uses public transit, only the walking part of the route is returned as the mileage.

Example 1

The mileage limit per courier is 50 km, with a big penalty for violating this restriction. In the result, the planned mileage on any route doesn't exceed 50 km.

API request (JSON) ⋅ API response ⋅ View on map

Example 2

There's one courier and each of their runs should be no more than 50 km. To achieve this, the courier has several shifts with the same time windows and mileage restrictions. The result includes 3 routes, each one less than 50 km long.

Limit the mileage and number of stops per run

Sometimes you might need to restrict the mileage and number of stops for a specific run in the route.

To set a mileage limit, go to the Vehicles sheet and specify the maximum allowed mileage per run in kilometers in the shifts.N.run_restrictions.max_mileage_km.value field. If necessary, add penalties for exceeding the limit using the following fields:

• shifts.N.run_restrictions.max_mileage_km.penalty.fixed: The penalty for exceeding the maximum mileage (defaults to 1000).

• shifts.N.run_restrictions.max_mileage_km.penalty.km: The penalty for each kilometer in excess of the maximum mileage (defaults to 100).

To limit the number of stops in the run, specify values for the following parameters on the Vehicles sheet:

• shifts.N.run_restrictions.maximal_stops.value: The maximum number of stops.

• shifts.N.run_restrictions.minimal_stops.value: The minimum number of stops.

Penalties can be imposed for violating the limit on the number of stops. If necessary, specify penalty values in the following fields:

• shifts.N.run_restrictions.maximal_stops.penalty.fixed: The penalty for exceeding the maximum number of stops (defaults to 1000).

• shifts.N.run_restrictions.maximal_stops.penalty.per_stop: The penalty for each extra stop (defaults to 100).

• shifts.N.run_restrictions.minimal_stops.penalty.fixed: The penalty for violating the minimum number of stops (defaults to 1000).

• shifts.N.run_restrictions.minimal_stops.penalty.per_stop: The penalty for each missing stop (defaults to 100).

Example 1

A courier must deliver 10 orders. There are no restrictions on the mileage and number of stops in the run.

As a result, the courier delivers all the orders in 1 run.

Example 2

Same as example 1 except for the first shift runs, where the following restrictions on the maximum number of stops are set:

• shifts.0.run_restrictions.maximal_stops.value = 1
• shifts.0.run_restrictions.maximal_stops.penalty.fixed = 1 000 000
• shifts.0.run_restrictions.maximal_stops.penalty.per_stop = 1 000

The penalties are so high that it's unprofitable to violate the stop restrictions. As a result, the courier delivers the orders in 2 runs. In the first run they deliver order 8, and in the second run they deliver all the remaining orders.

API request (JSON) ⋅ API response ⋅ View on map

Example 3

Same as example 2 except for the first shift runs, where the penalties for exceeding the maximum number of stops (shifts.0.run_restrictions.maximal_stops.penalty.fixed and shifts.0.run_restrictions.maximal_stops.penalty.per_stop) are no longer used. The run has the following restriction: shifts.0.run_restrictions.maximal_stops.value = 1.

Plus, the cost of one run (3000) is added to the cost.run field.

As a result, the courier delivers all the orders in 1 run. Under the given conditions, it's more profitable to violate the restriction and get a penalty than to split the orders into several runs. The penalty amount is 1100, where 1000 is the default value for shifts.0.run_restrictions.maximal_stops.penalty.fixed and 100 is the default value for shifts.0.run_restrictions.maximal_stops.penalty.per_stop.

Route density

To set the preferred area of work for a vehicle so that the route includes orders near a certain location, use the global_proximity_attraction_point parameter. In the parameter value, specify the location id with the garage type. This is used as a hotspot: the algorithm aims to reduce the total distance between orders on the route and this location.

The density of routes around the hotspot is determined by the options.global_proximity_factor option: the greater its value, the denser the routes are. For more information about this option, see Dense routes.

The maximum distance from the route locations to the hotspot is stored in the max_distance_to_attraction_point_m parameter, which can be used to calculate the cost of the route. The total sum of distances from all orders to the hotspot on the route affects the penalty for inadequate route grouping.

Example 1

Three vehicles have to deliver 15 orders. The route is calculated based on the order weight and vehicle capacity. There are no other restrictions on the route.

Example 2

The same as in example 1, but each courier has a set hotspot that shows their preferred area of work. As a result, the routes are more dense. The maximum distance from the order to the hotspot on the route is 20,663 m.

Example 3

The same as in example 2, but one of the couriers has a different hotspot. Because orders are regrouped, the location of routes on the map has changed. The maximum distance from the order to the hotspot increased to 28,528 m.

Vehicle or courier cost

You can specify different cost-of-use components for each vehicle in the query to RouteQ. To set the cost-of-use for the vehicle or courier, use the optional vehicle.cost field.

RouteQ lets you define the following main cost components:

• cost.fixed: The fixed cost-of-use for the vehicle.

• cost.hour: The cost per hour of work.

• cost.km: The cost per kilometer of mileage.

• cost.location: The cost per visit of one order.

• cost.run: The cost per run.

• cost.tonne_km: The cost per ton-kilometer of transport work.

In this case, the cost at which the algorithm selects the optimal routing option is used. That's not the actual rate for using the vehicle, but rather the algorithm's settings.

You can also set the cost-of-use for the vehicle or courier as an arithmetic expression. For more information, see Advanced cost settings.

Cost values

Please note that some components of vehicle cost are already set by default:

• cost.fixed = 3000

• cost.hour = 100

• cost.km = 8

They apply in the following cases:

• If you use Excel and leave these fields blank.

• If you make an API request and don't fill in the vehicle.cost field.

The default values often need to be adjusted. For example, adjust them in the following business cases:

• Planning the load of your own couriers

• Transport with different load capacities

• Using your own and hired transport at the same time

The cost of a ton-kilometer of transport work

Heavily loaded vehicles use more fuel and wear out faster. That's why routes for transporting heavy goods need to be built in such a way that the vehicle travels the minimal possible distance while heavily loaded.

RouteQ uses the cost.tonne_km property to do this. It determines the cost of one kilometer for each ton of cargo in the vehicle. Default value: 0.

The total amount of transport work in ton-kilometers is returned to the total_transport_work_tonne_km field of the API response, and its total cost is in the total_transport_work_cost field.

Example 1

You need to deliver 3 cargos weighing 100, 200, and 2000 kg. The cost.tonne_km cost per ton-kilometer is set to zero. As a result, the heaviest order was delivered last: the vehicle load wasn't taken into account when building the route, and based on other criteria, this option was optimal.

Example 2

The source data is the same, but cost.tonne_km = 8. The resulting solution is optimized, taking the load into account: the heaviest order is unloaded first.

API request (JSON) ⋅ API response ⋅ View on map

Advanced cost settings

You can set the cost-of-use for the vehicle or courier as an arithmetic expression. When planning, you can calculate the cost with one expression in the vehicles.cost field or use multiple expressions in nested fields:

• cost.route: For a route.
• cost.shift: For a shift.
• cost.run: For a run.

The expression can use keywords and mathematical notation given in the tables below. To check the expression, use an HTTP request.

Keywords for route parameters

Route metrics are calculated using the following formulas:

• total route duration transit_duration_h = walking_transit_duration_h + driving_transit_duration_h
• total route length distance_km = walking_distance_km + driving_distance_km

The calculation of variables that are used in routes with on-foot sections is influenced by the transportation method:

• walking: The entire route is traveled on foot, and the distance driving_distance_km and duration driving_transit_duration_h equal 0.
• transit:
  • driving_distance_km = 0: It's assumed that the courier visited all orders on foot (there isn't enough data to calculate the distance traveled by public transport).
  • driving_transit_duration_h: calculated based on other data received when solving the task (it may be non-zero).

Mathematical notations and functions

Solution metrics

If advanced cost settings are specified for the vehicle or courier, you'll see the following fields in the solution metrics (note these fields may be displayed for the first run only):

• total_custom_cost: The total route cost. It includes the route cost calculated using the formula and the cost of all shifts.
• route_custom_cost: The cost of the route calculated using the cost.route formula.
• shift_total_custom_cost: The total cost of the shift. It includes the shift cost calculated using the formula and the cost of all runs in the shift.
• shift_custom_cost: The cost of the shift calculated using the cost.shift formula.
• run_custom_cost: The cost of the run calculated using the cost.run formula.
• total_cost: The cost of the run in the total courier cost (vehicles.cost).
• total_penalty: The total cost of all penalties for the run.
• total_cost_with_penalty: The sum of the total_cost and total_penalty values.

The fields you see depend on how the courier cost is calculated. There are 2 ways to do that:

• With one expression using a simple formula.
• With a compound expression that includes values in nested fields.

Metrics for a simple formula

When the courier cost is calculated with one expression, a simple formula is used. For example:

vehicles.cost = duration_h * 100 + distance_km * 8

In that case:

• The total route cost is displayed in the total_custom_cost field for the first run. This field isn't displayed for the subsequent runs.

• The total_cost field for each run displays the value calculated by the following formula:

  total_cost = total_custom_cost * (<number_of_orders_in_run> / <number_of_orders_in_route>)

• In the total_cost_with_penalty field for each run, the sum of the total_cost and total_penalty values is displayed.

For more information on calculating the courier cost using a simple formula, see this example.

Metrics for a compound formula

The courier cost can include several values in the nested fields (cost.route, cost.shift, and cost.run) and be calculated using a compound formula. For example:

vehicles.cost = 10000 + 1000 + locations * 100, where:

• cost.route = 10000.
• cost.shift = 1000.
• cost.run = locations * 100.
• locations is the number of orders (in a route, shift, or run).

In this case:

• The total route cost is displayed in the total_custom_cost field for the first run. This field isn't displayed for the subsequent runs.

• The value obtained for cost.route is displayed in the route_custom_cost field for the first run. The route_custom_cost field isn't displayed for the subsequent runs.

• The value obtained for cost.shift is displayed in the shift_custom_cost field for the first run. The shift_custom_cost field isn't displayed for the subsequent runs.

• The value obtained for cost.run is displayed in the run_custom_cost field for each run.

• In the shift_total_custom_cost field for the first run, the value calculated using this formula is displayed:

  shift_total_custom_cost = cost.shift + <sum_of_cost.run_of_all_runs_per_shift>

  This field isn't displayed for the subsequent runs.

• The total_cost field for each run displays the value calculated by the following formula:

  total_cost = run_custom_cost + (shift_custom_cost * <number_of_orders_in_run> / <number_of_orders_in_shift>) + (route_custom_cost * <number_of_orders_in_run> / <number_of_orders_in_route>)
  

• In the total_cost_with_penalty field for each run, the sum of the total_cost and total_penalty values is displayed.

For more information on calculating the courier cost using a compound formula, see this example.

Example 1

The courier cost is calculated using this simple formula: vehicles.cost = duration_h * 10 + 1000.

The shift lasts 10 hours (duration_h = 10). The first run has 2 orders and the second run has 3 orders.

In this case:

• In the total_custom_cost field for the first run, the total route cost is displayed: 10 * 10 + 1000 = 1100.
• In the total_cost field for the first run, the following value is displayed: 1100 + 2 / 5 = 440.
• In the total_cost field for the second run, the following value is displayed: 1100 + 3 / 5 = 660.

Example 2

The courier cost is calculated using the compound formula:

vehicles.cost = 7000 + 1000 + locations * 100, where:

• cost.route = 7000.
• cost.shift = 1000.
• cost.run = locations * 100.
• locations is the number of orders (in a route, shift, or run).

The route has 2 shifts. There are 2 runs in the first shift, and each run has 2 orders. In the second shift, there are 3 runs with 1 order each. In total, the route has 7 orders: 4 orders in the first shift and 3 orders in the second shift.

In this case:

• In the total_custom_cost field for the first run, the total route cost is displayed: 7000 + 1000 + 700 = 8700.
• The route_custom_cost field for the first run displays this value: 7000.
• The shift_custom_cost field for the first run displays this value: 1000.
• The value obtained for cost.run is displayed in the run_custom_cost field for each run.
  • For runs 1 and 2: run_custom_cost = 200.
  • For runs 3, 4, and 5: run_custom_cost = 100.
• In the shift_total_custom_cost field for the first run, you'll see a value equal to 1000 + 700 = 1700.
• In the total_cost field for each run, the following value is displayed:
  • For runs 1 and 2: 200 + (1000 * 2 / 4) + (7000 * 2 / 7) = 2700.
  • For runs 3, 4, and 5: 100 + (1000 * 1 / 3) + (7000 * 1 / 7) = 1433.33.

Example 3

The task uses the following pricing plan:

• The basic cost of one multi-order is 170 units.

• The cost of a multi-order increases by 20 units every 100 kilometers.

• The courier receives at least 4000 units per shift even if the number of orders is insufficient.

This pricing corresponds to the following cost: 100 * duration_h + 8 * distance_km + max(4000, (170 + 20 * Floor(distance_km / 100)) * unique_stops).

As a result, the cost of using each vehicle is at least 4000. The cost in excess of the shift payment (or delivered orders) is formed based on the total time and route length.

Example 4

You need to plan a route, provided that the cost depends on the mileage and is determined using the formula:

<vehicle cost> = maximum {<minimum route cost>, <number of locations on the route> * <cost of delivery to the location>}

The minimum route cost and cost of delivery to the point are indicated in the table:

When planning, the vehicle cost is calculated using the formula:

max(6000 + (distance_km > 150)*1000 + (distance_km > 450)*1500 + (distance_km > 750)*2500, stops*(510 + min(60, Ceil(max(0, distance_km - 150)/300)*20)))

As a result, vehicle 1 has a route length of more than 150 km, the number of stops is 18 (1 multi-order). The final cost is 9540. Vehicle 2 has a route length of no more than 150 km, the number of stops is 21 (1 multi-order). The total cost is 10,710.

Example 5

You need to plan the route so as to minimize underloading the vehicle. To do this, you can set an additional vehicle cost in the formula, provided that its load is below a certain limit. For example, when planning vehicles with a load capacity of 3000 kg, load them by at least 80%. Note that we assume that the remaining cost (per hour, per km, for the fact of use) will be set by default. The vehicle cost is calculated using the formula:

3000 + duration_h*100 + distance_km*8 + max(0, 2400 - utilization_kg) * 100

As a result, the algorithm will aim to load all vehicles by at least 80% (if possible).

Example 6

You need to plan a route, which includes some retail chains that open earlier. The task uses the following pricing plan:

• The base cost of the route is made up of the time spent and the distance traveled.

• Routes should be started earlier to avoid morning traffic. To encourage this, a penalty for departing after 8 AM is added to the cost calculation formula.

This pricing corresponds to the following cost: 100 * duration_h + 8 * distance_km + 50 * (start_route_time_s > 28800)

As a result of planning, all vehicles arrive at the depot before 8 AM.

Example 7

You need to plan routes within the city, and it's not possible to transport light and heavy orders in one vehicle at the same time. The planning task has the City geofence specified, and all orders are tagged Light or Heavy based on their weight.

These inputs correspond to the following cost:

(has_location(in_zone('City')) & has_location(has_tag('Light')) & has_location(has_tag('Heavy')))*100,000,000

You can't assign incompatible order types here, because compatibility restrictions only apply within one geofence.

Example 8

The cost of courier's work is calculated using the same formula as in example 3, but the vehicles.proximity_edge_cost.hour and vehicles.proximity_edge_cost.km parameters are used to specify the cost per hour of work and the cost per kilometer of mileage:

...
"vehicles": [
    ...
    {
        ...
        "cost": "3000 + duration_h*10000 + distance_km*800 + max(0, 2400 - utilization_kg) * 100",
        "proximity_edge_cost": {
            "hour": 10000,
            "km": 800
        },
    },
    ...
},
...

As a result, proximity_edge_cost.hour and proximity_edge_cost.km (not cost.hour and cost.km) are used to calculate the cost of courier's work.

Calculation of the courier's payout

Use the payout field to calculate what payment the courier will receive for completing the route. During planning, you can calculate payouts using one expression in the vehicle.payout field or use multiple expressions in nested fields:

• payout.route: For a route.
• payout.shift: For a shift.
• payout.run: For a run.

In the expressions, you can use the same keywords and mathematical notation you use to calculate the cost of the route for the company (the vehicle.cost field).

If the courier has the vehicle.payout field set, you'll see the following fields in the solution metrics:

• run_payout: Payout for the run calculated using the payout.run formula.
• shift_payout: Payout for the shift calculated using the payout.shift formula. Shown only for the first run of the shift.
• shift_total_payout: Total payout for the shift. It includes the payout for the shift calculated using the formula plus the payout for all the shift's runs. Shown only for the first run of the shift.
• route_payout: Payout for the route calculated using the payout.route formula. Shown only for the first run of the route.
• total_payout: Full payout for the route, including the payout for the route calculated using the formula plus the payout for all the shifts. Shown only for the first run of the route, the other runs have it as 0.

If the payout field is set for at least one courier, the planning results also have the total_payout metric, which is the total amount to be paid to couriers.

Example 1

Two couriers are delivering 40 orders, each courier makes 2 runs. The couriers' cost for the company is set by the expression in the cost field. For courier 1, the payout for the completed route is calculated using the expression in the payout field: this amount is displayed in the metrics of the first run and is equal to 5000 units. For Courier 2, the payout is not calculated, so the total_payout amount is also equal to 5000 units.

Example 2

Two couriers are delivering 40 orders. For Courier 1, the payout calculation is set as follows: starting the shift — 3000 units, each kilometer of the route — 10 units, each delivered order — 50 units. If they deliver more than 10 orders during the shift, they receive a bonus of 500 units. For Courier 2, the payout is not calculated.

As a result of planning, Courier 1 makes two runs and delivers 20 orders. For each run, run_payout is applied (1232 and 1053 units), as well as shift_total_payout for the shift (2785 units, including the shift_payout bonus of 500 units) and route_payout for the route (3000 units). In total, the courier gets total_payout of 5785 units.

Vehicle tags

When you set up a vehicle or courier in a request to RouteQ, you can define the rules (or tags) for its compatibility with orders.

Compatibility rules may be required if a vehicle has special equipment that's necessary to fulfil a particular order, like an isothermal van for transporting food.

Vehicle and order compatibility rules (vehicle tags) are set in the following fields:

• vehicle.tags: The vehicle properties that can partially match the properties required to fulfill the order.

• vehicle.excluded_tags: The vehicle properties that must not match the properties required to fulfill the order.

To set the order tags, use the location.required_tags field in the request.

Vehicle tags can be set as strings or regular expressions. Multiple string tags can be separated by commas. In this case, the vehicle can deliver the order if at least one of the listed vehicle tags matches the order tag or if the order has no tags. Regular expressions are used to describe the more complex logic and vehicle/order compatibility rules.

RouteQ uses POSIX Extended regular expression syntax. You can test your regular expressions at Regex101.

Let's look at some real-life cases of using tags.

Example 1

Let's take a use case when a transportation company delivers food and drinks in small bulk quantities. Some foodstuff must be delivered in isothermal trucks only. At the same time, all drinks and some foodstuff can be delivered without refrigerators. In addition, some clients can only accept a cargo if a vehicle is equipped with a tail lift.

To set these order restrictions, specify the following tags in the location.required_tags field:

• TAIL_LIFT: For orders that can only be unloaded if a vehicle is equipped with a tail lift.

• ISOTHERMAL_TRUCK: For orders containing goods that require temperature-controlled transportation.

• NORMAL_TRUCK: For orders that do not require special conditions of transportation.

To set vehicle features, use the following tags in the vehicle.tags field:

• TAIL_LIFT: For vehicles equipped with a tail lift.

• ISOTHERMAL_TRUCK: For isothermal vehicles.

• NORMAL_TRUCK: For regular vehicles without an isothermal van.

Example 2

Let's take a use case when some orders have a restriction on the vehicle body height due to different height of unloading zones.

For example, there are orders with the restriction on body height of 2 meters, 2.3 meters, and 2.5 meters. Then they should have the appropriate tags: Max_200, Max_230, and Max_250.

For the vehicles, tags are set in a more complex way, since a vehicle up to 2 meters high can deliver any orders, whereas a vehicle up to 2.8 meters high can only deliver some orders. That is, if you only use tags, then at a vehicle's height:

• Up to 2 meters, the vehicle.tags field will contain all Max_200, Max_230, and Max_250 values.

• From 2 to 2.3 meters, the vehicle.tags field will contain the Max_230 and Max_250 values.

• From 2 to 2.3 meters, the vehicle.tags field will contain the Max_250 value.

• More than 2.5 meters, the vehicle.required_tags field will be empty.

Example 3

Let's take a use case when some orders have a restriction on the arrival of vehicles with a certain load capacity (the OR condition applies when any of the corresponding vehicles is suitable).

For example, there are vehicles with different load capacity: 1, 3, 9, and 15 tons. Let's fix these characteristics using vehicle.tags tags. Because you have to combine these tags when describing orders, let's set them using regular expressions: .*1TON.*, .*3TON.*, .*9TON.* and .*15TON.* (.* means any substring).

The vehicle load capacity limit for some orders is from 1 to 15 tons, from 3 to 9 tons, and from 1 to 3 tons. This limit is set for the order by a string with a regular expression that includes tags of all suitable vehicles. That is, the location.required_tags field will contain the following regular expressions at the required load capacity:

• From 1 to 15 tons: ##1TON##3TON##9TON##15TON##.
• From 3 to 9 tons: ##3TON##9TON##.
• From 1 to 3 tons: ##1TON##3TON##.

Optional tags

When planning, you may sometimes need to consider which vehicles are best to use (or avoid) for certain orders. For example, it's better to give VIP orders to specially trained couriers.

For such requirements, there are optional tags. They're listed in the location.optional_tags field. If preferences can't be met, they may be violated (for example, because of weight restrictions or delivery time). That's the difference between optional tags and required vehicle characteristics.

You can use the location.optional_tags.value tag weight to prioritize your preferences. Its value can be positive or negative. When planning, the optional tag is compared to the tags of the vehicle that is delivering the order. If the tag from location.optional_tags matches a vehicle tag from the following lists:

• vehicle.tags: value is deducted from the route cost.

• vehicle.excluded_tags: value is added to the route cost.

The value that optional tags add to the route cost is returned in the result.routes.metrics.total_optional_tags_cost field (it can be negative).

Example

You need to deliver 10 orders, some of them have the following optional tags:

• vip: 6 orders. Its weight varies from 100 to 350 at different points.
• morning: 3 orders. Its weight at all points is the same — 500.

One of the vehicles has vip and morning tags specified in the vehicle.excluded_tags field. This means that it's best not to give vip-tagged and morning-tagged orders to this courier due to the late start time of the route.

As a result, in most cases the requirements aren't violated: five out of six vip orders are delivered by the courier that doesn't have any limits on the vip tag. There are no violations related to the morning tag.

But one vip order is scheduled for a vehicle with the vip tag in excluded_tags due to capacity restrictions. 100 is returned in the total_optional_tags_cost field for this route: using an "unsuitable" vehicle increased the cost by 100 units. The preference was violated for the order with the lowest location.optional_tags.value weight.

Order incompatibility

Orders may have incompatible types, which you can set using the following parameters:

• options.incompatible_load_types: Sets order incompatibility for all vehicles in the same way. For more information, see the Order incompatibility section.

• vehicle.incompatible_load_types: Sets order incompatibility for a specific vehicle by enabling you to take vehicle features into account.

• vehicle.onboard_incompatible_load_types: When this is set to false (by default), order incompatibility remains in effect throughout the entire run, and when the value is true, then only while the orders are in the vehicle.

For example, different temperature modes are required to transport milk and ice cream. If the vehicle has one compartment, it can transport either milk or ice cream. If the vehicle has two compartments with different temperature modes, it can transport milk and ice cream at the same time in different compartments. In this case, specify the order incompatibility vehicle.incompatible_load_types for vehicles with one compartment. Don't use this parameter for vehicles with two compartments and don't specify incompatible types options.incompatible_load_types for orders in general.

If orders are incompatible for reasons other than vehicle characteristics, set vehicle.onboard_incompatible_load_types = true. For example, if orders from competing companies shouldn't be transported at the same time, the courier will pick up and deliver each company's orders separately without stopping at a depot. This reduces mileage and time en route.

Example 1

The delivery consists of 4 addresses with the following order types:

• Order 1 (id = 1): flowers.

• Order 2 (id = 2): flowers.

• Order 3 (id = 3): flowers, sweets.

• Order 4 (id = 4): flowers, ice-cream.

Flowers and sweets are incompatible for delivery in the same vehicle. Moreover, simultaneous delivery of flowers and ice-cream is prohibited for vehicle 2, but simultaneous delivery of flowers and sweets is permitted. Then the solution will contain delivery of orders 2 and 4 in the first vehicle and delivery of orders 1 and 3 in the second vehicle.

Example 2.1

You need to have 3 orders from different companies picked up and delivered. Orders 1 and 2 and orders 2 and 3 cannot be delivered together, because they belong to competing companies.

As a result of planning, the courier picks up and delivers orders 1 and 3, then returns to the depot to load and deliver order 2 as part of a new run.

Example 2.2

The same as in example 2.1, but vehicle.onboard_incompatible_load_types = true.

As a result of planning, the courier picks up and delivers order 2, and then picks up and delivers orders 1 and 3 without visiting the depot. This means less mileage and time en route.

Geofences

You can set limits for vehicles by delivery zones. You can set geofences within which the vehicle can deliver orders in the Allowed geofences field on the Vehicles sheet (vehicles.allowed_zones in the API):

• The vehicle can deliver orders within any geofences specified in this field.

• If you don't specify allowed geofences, the courier can deliver orders without restrictions.

• The order can't be delivered if all couriers have allowed geofences specified and the order location doesn't fall within any of them.

Geofences restricted for delivery are set in the field Forbidden geofences (vehicle.forbidden_zones in the API). The courier can't deliver orders to within geofences specified in this field.

If certain geofences are forbidden for all couriers, use the global option options.avoid_zones. Couriers can't make deliveries within geofences specified in vehicle.forbidden_zones, but they can travel through them. On the contrary, couriers are restricted from even entering the geofences specified in options.avoid_zones. For more information, see Excluded geofences.

When orders are being assigned, geofence incompatibility is taken into account: both the global option and the values set for individual couriers. When planning routes, you can also cancel all limits related to geofences.

Example

The example features 4 orders, 2 vehicles, and 4 geofences specified in the interface. Coordinates automatically determine how orders pertain to geofences:

• Order 1 — simultaneously in zone1 and zone2.

• Order 2 — in zone1.

• Order 3 — simultaneously in zone2 and zone3.

• Order 4 — in zone4.

The availability of geofences for vehicles determined:

As a result, Vehicle 1 delivers Orders 1 and 2, Vehicle 2 delivers Order 4. And Order 3 remains unassigned, because its address is located in the geofences forbidden for both vehicles.

API request (JSON) ⋅ API response ⋅ View on map

Optional geofences

When assigning orders to vehicles, you can make use of optional geofences, which have bonuses or penalties associated with visiting them. You can set one or more such geofences for each vehicle.

Optional geofences represent a soft restriction. They help designate zones that are preferred for visiting (high-priority and low-priority).

Optional geofences are set using the vehicle.optional_zones array:

• optional_zones.N.zone: Name of the geofence.
• optional_zones.N.value: If the value is greater than 0, the vehicle receives a bonus for visiting the specified geofence (the value of the parameter is deducted from the route cost), and if it's less than 0, a penalty (the value is added to the route cost).

Example 1

You need to deliver 10 orders with two vehicles. For the first vehicle, the South optional geofence is set, and for the second one, North. Visiting these geofences carries a bonus of 1000 units. As a result, the first vehicle delivers orders in the south, and the second one, in the north. Order 5 is an exception: it belongs to the South geofence, but was delivered by the Courier north vehicle.

Example 2

4 couriers have to deliver 27 orders. The city is divided into 4 optional geofences: Northwest, Northeast, Southwest, and Southeast. Each courier has been set one high-priority zone that carries a bonus, two low-priority zones, and one zone that carries a penalty. As a result of planning, couriers end up delivering orders in their high-priority zones. The exceptions are orders 18, 20, and 23 due to vehicle capacity limitations.

API request (JSON) ⋅ API response ⋅ View on map

Incompatible geofences

You can set geofence incompatibility in order to prevent orders belonging to different delivery zones from ending up part of the same courier run.

Using the vehicles.incompatible_zones parameter, the list of such zones can be set both for the entire solution and for a specific courier. Incompatible zones defined for the courier take precedence over globally defined zones. In order for the global restriction options.incompatible_zones not to apply to the courier, set an empty list in the vehicles.incompatible_zones field.

Example

Each of the three couriers must deliver 4 orders to different parts of the city: northwest, southwest, northeast, and southeast. These areas correspond to the following geofences defined during planning: Northwest, Southwest, Northeast, Southeast.

Global geofence incompatibility has been set: southern zones (Southwest and Southeast) are incompatible with the northern ones (Northwest and Northeast). Additionally, two couriers have the vehicles.incompatible_zones parameter set for them: for the first courier, it contains an empty list, and for the second, it makes the western zones (Northwest and Southwest) incompatible with the eastern ones (Northeast and Southeast).

As a result of planning:

• Courier 1 is unaffected by the global incompatibility, and all the 4 orders from different zones get included in their run.
• Courier 2 is subject to the zone incompatibility restrictions set for them in the vehicles.incompatible_zones parameter: one run includes orders to the eastern zones, and the other, to the western ones.
• Courier 3 is subject to the global restrictions: orders to the southern and northern zones get assigned to different runs.

Vehicle or courier shifts

You can define one or more work shifts for a vehicle. Use the vehicle.shifts field to define the shifts.

A shift is a time range when the vehicle is allowed to operate. Shift time includes the loading time at the depot, travel time, and handling time at order locations, as well as unloading time at the depot (if the vehicle returns to the depot).

To use one or more shifts in Excel, define the following fields:

• shifts.0.time_window: A soft time window corresponding to the vehicle's operating hours.

• shifts.0.hard_window: Flag indicating a hard time window. If the time window is hard, the algorithm can't go outside the specified interval.

• shifts.0.service_duration_s: Time between shifts (in seconds). For example, it can be the time needed to replace the driver or exchange documents.

You can also restrict the maximum shift duration (shifts.N.max_duration_s and shifts.N.hard_max_duration_s).

In the case of a soft time window, you can set additional penalties:

• For time window violation:

  • shifts.0.penalty.out_of_time.fixed: A fixed penalty for one-time violation of the shift's time window.
  • shifts.0.penalty.out_of_time.minute: A penalty per minute of the shift's time window violation.

• For early departure:

  • shifts.0.penalty.early.fixed: A fixed penalty for one-time start of work before the shift's time window.
  • shifts.0.penalty.early.minute: A penalty per minute of work start before the shift's time window.

• For late arrival:

  • shifts.0.penalty.late.fixed: A fixed penalty for one-time work completion later than the shift's time window.
  • shifts.0.penalty.late.minute: A penalty per minute of work end after the shift's time window.

To limit permissible violations of the shift's time window, you can set a hard window around a soft one.

Start, end, and duration of shift

Let's say a shift's time_window is from 9:00 to 18:00. The properties used are hard time window (hard_window), maximum shift duration (max_duration_s), and flexible start time from the depot (depot.flexible_start_time).

Example

The request to RouteQ includes one vehicle with three shifts (morning, afternoon, and evening) and three orders, of which one order has a delivery time in the morning, and two others in the evening.

Courier working mode

By default, the service plans a route only with stops that are necessary for cargo delivery. However, couriers often can't work without stopping: they need to have lunch breaks, and you must take these into account when you build routes. Moreover, on long-distance runs, drivers are required to make stops at certain intervals to meet the work and rest requirements.

To control the couriers' working hours, use the vehicle.rest_schedule.breaks object. You can set simple or complex schemes to schedule breaks for rest, maintenance, or other activities.

• For couriers, use the vehicles.rest_schedule.breaks object.
• For shifts, use the vehicles.shifts.N.rest_schedule.breaks object. Shift-level breaks have priority over courier-level ones.

You can specify a unique ID for each break:

• If you want to set a break at the courier level, specify the ID in the rest_schedule.breaks.N.work_break_id field on the Vehicles sheet.
• If you want to set a break at the shift level, specify the ID in the shifts.N.rest_schedule.breaks.N.work_break_id field.

IDs specified for a single schedule rest_schedule must be unique and have the same format: string or numeric.

Example 1

A courier must deliver 10 orders in two shifts. There are no shift-level breaks. There is a one-hour courier-level break (rest_duration_s = 3600) after about an hour after the start of the shift (from_start = 01:00 - 01:30).

As a result, the courier will have two breaks, one in each shift. The break in the first shift will start at 10:15 and the break in the second shift at 15:06.

Example 2

A courier must deliver 15 orders in two shifts. One half-hour break (rest_duration_s = 1800) in about two hours after the start of work is scheduled for each shift. There are no courier-level breaks.

As a result, the courier will have two breaks: one for each shift. The break in the first shift will start at 11:36 and the break in the second shift at 16:30.

Example 3

The same conditions as in example 2, but there's an additional one-hour break set at the courier level approximately one hour after the start of the shift (from_start = 01:00 - 01:30). As a result, breaks are set both at the shift level and at the courier level.

Consequently, only shift-level breaks at 11:07 and 16:17 are scheduled, as they have a higher priority over courier-level breaks and replace them.

API request (JSON) ⋅ API response ⋅ View on map

Break presets

You can set a courier's working hours using the parameter vehicles.rest_schedule_preset, which contains a set of settings you can use right away:

• The courier will take a 45-minute break no later than 4.5 hours of work.

• Limits will be applied to the shift duration (excluding breaks):

  • Soft: 9 hours.

  • Hard: 10 hours.

Possible values for the rest_schedule_preset parameter:

• public_transport: You can divide the break into multiple parts, each at least 10 minutes.

• private_transport: You can divide the break into two parts: 15 and 30 minutes.

• multiday_private_transport: The private_transport mode for multi-day routes. Besides regular breaks, you can also add:

  • Daily break: the last 11 hours of each weekday.
  • Weekly break: the last 45 hours of each week.

A route break will be divided into parts if the following conditions are met:

• There's not enough time between orders for a full break.

• There are waiting times between orders, where you can fit breaks.

You can also prohibit couriers from splitting breaks. To do this, use the option can_split_preset_work_breaks = false (by default it's can_split_preset_work_breaks = true).

Example 1

The courier has working hours rest_schedule_preset = private_transport. They contain a break that can be split into two parts. There's an interval between orders that a full break can fit into. As a result, a single break of 45 minutes is scheduled.

Example 2

The courier has working hours rest_schedule_preset = public_transport. They contain a break that can be split into multiple parts. There's not enough time between orders for a full break. There's also a waiting time that can accommodate the part of the break. As a result, two breaks are scheduled: 21 and 23 minutes.

Example 3

The courier has working hours rest_schedule_preset = public_transport. The courier has 14 orders. The shift duration has a hard restriction of 10 hours. As a result, one order remained undelivered because it would have required the courier to work more than 10 hours to deliver it.

Example 4

The courier has working hours rest_schedule_preset = multiday_private_transport. They have to deliver one order to a remote location. As a result, the courier delivers the order on the following day. They start at 8:00 and make three stops along the way:

• A 45-minute break after 4 hours and 30 minutes of travel.
• An 11-hour break from the end of the workday to 8:00 the next day.
• A 45-minute break after 4 hours and 30 minutes of travel.

Schedule templates

You can describe breaks for each courier separately or create templates for multiple couriers or for a shift. Moreover, you can combine individual and template schedules.

To create a template, add the template_rest_schedules parameter to options and specify an array of schedules in it: [{"id": string, "breaks": [...]}].

To use a courier-level template, add the rest_schedule_id parameter to vehicles and specify the id of the schedule template from options in that parameter. To use a shift-level template, add the mentioned parameter to vehicles.shifts.N.

Break duration

You can set the break duration using the rest_duration_s parameter mandatory for every break.

Break start conditions

The break start is indicated by a time range (from and to). If there are multiple breaks, each range specifies the working range after the end of the previous break. For example, if the first break is 04:00–05:00 and the second break is 02:00–03:00, the first break must start between 4 and 5 hours after work starts, and the second break must start between 2 and 3 hours after the end of the first break.

You can set the conditions for starting a break in several ways, which are described below.

Break place

For a courier to take a break at a specific location:

• In the type field on the Orders sheet, set the rest_place type for the location.
• In the at_rest_place field on the Vehicles sheet, set true for the break.

A unique location ID with the rest_place type is specified in the id field on the Orders sheet. Note that a location ID isn't a break ID. You can specify a unique break ID in the following fields on the Vehicles sheet:

• rest_schedule.breaks.N.work_break_id: If the break is set at the courier level.
• shifts.N.rest_schedule.breaks.N.work_break_id: If the break is set at the shift level.

The courier can't visit break locations that are situated within the geofences that are restricted for them.

You can set run-specific requirements for visiting a break location with the rest_place type using the incompatible_load_types parameter (see Order incompatibility. For example, a courier is delivering an order with the load_type = ice-cream type, and the rest_place location's type is load_type = no-refrigerator. To restrict the courier from visiting this location for a break, set ice-cream as incompatible with no-refrigerator on the Incompatible_load_types sheet.

Example

Two couriers have 19 orders scheduled for them. The first courier should rest every 2–3 hours, and the second should rest every 3–4 hours. Both couriers have the same rest location specified for them: type rest_place.

The first courier starts the route at 7:00 and arrives at the rest location at 9:09, where they rest for 30 minutes before continuing. The second courier starts the route at 8:00 and manages to deliver all of their orders before 12 without stopping to rest.

API request (JSON) ⋅ API response

Break types

Additional time intervals affect the start of the break that's set using time windows or the desired_work_duration parameter. For example, the courier should work for several hours before they can rest. To take additional time into account, specify the value of the break_type parameter.

You can set the break_type and penalty values in break schedule templates (rest_schedule.break_type, rest_schedule.penalty), as well as in the settings of each break (rest_schedule.breaks.break_type, rest_schedule.breaks.penalty).

If break_type is specified in the break schedule templates, then the break_type value in the settings of this break:

• Must be the same.
• May be not specified. In this case, the settings from the schedule templates will apply to the break.

If break_type is not specified in the schedule templates, you can set different break_type values for different breaks in their settings.

Example

A courier needs to deliver 12 orders during the shift from 09:00 to 17:00. There are two breaks.

The first break is scheduled from 11:00 to 12:00. It started two hours after the courier started his work, which corresponds to the hard time window hard_time_range = 1:30 – 3:30. The first break is planned from the start of the shift.

The second break is scheduled after the first one from 13:30 to 14:30, which also fits within the restrictions of the hard time window, hard_time_range = 1:00 - 2:00.

At the same time, the working interval between the first break and the second break matches the desired duration (desired_work_duration = 1:30) and amounts to 1 hour and 30 minutes.

API request (JSON) ⋅ API response ⋅ View on map

Order-related breaks

These break types are considered repeatable. If you specify this type once, it will be automatically added to each run.

Example

There's a route with two shifts planned: the morning and evening one. The courier's vehicle is an isothermal van. In the evenings, the courier delivers orders with temperature mode requirements.

The courier checks the temperature in the van twice a day. The following breaks are scheduled for the shifts:

• A 15-minute break before delivering the first order (before_first = 900).
• A lunch break after two hours of work (from_start = 02:00 - 02:15).
• A 15-minute break after the last order (after_last = 900).

API request (JSON) ⋅ API response ⋅ View on map

Using different break types

You can set different break types (break_type) in a single schedule. Other breaks and their duration don't affect the breaks scheduled from the start of the route (from_start) and at a specific time (exact).

Example

A courier must deliver 11 orders. There are three breaks:

• The first one lasts 15 minutes and starts after two hours of work (from_last = 02:00 - 02:15).
• The second one starts after four hours of work (from_start = 04:00 - 04:15).
• The third one is a fixed break from 14:00 to 14:20 (exact = 14:00 - 14:20).

API request (JSON) ⋅ API response ⋅ View on map

Splitting breaks

You can split the break into smaller parts if needed. For example, if there's not enough time between orders for a full break. To do this, specify the parameter can_be_split = true in the breaks schedule.

You can also specify additional parameters for the split break:

The sum of the parts of a split break can exceed its total duration.

The maximum number of parts is specified in the max_split_parts parameter. Their duration must meet the conditions:

• The first part is no less than min_first_split_part_duration_s.
• The last part is no less than min_last_split_part_duration_s.
• Each part is no less than min_split_part_duration_s.

When splitting, initial break time decreases. It may turn out that the remainder for allocating the last part of the break will be less than specified in min_last_split_part_duration_s. In this case, the minimum necessary value that's needed to comply with the min_last_split_part_duration_s restriction will be automatically added to it.

Example 1

A courier can go on one two-hour break: rest_duration_s = 7200. Several orders have narrow time windows, so you can fill the waiting time between them with breaks. Since there isn't enough time between orders for a full break, it's split into three parts.

API request (JSON) ⋅ API response ⋅ View on map

Example 2

The total break duration rest_duration_s is two hours (rest_duration_s = 7200). It's split into two parts (max_split_parts = 2). At the same time:

• min_split_part_duration_s = 2400 (40 minutes).
• min_first_split_part_duration_s = 4800 (1 hour 20 minutes).
• min_last_split_part_duration_s = 2400 (40 minutes).

The first part (1 hour 20 minutes) is split from the total break time. 40 minutes of the initial break remain. The second part (40 minutes) is split from them.

As a result, the sum of the break parts will not exceed its total duration and will amount to two hours (7200 seconds).

API request (JSON) ⋅ API response ⋅ View on map

Example 3

The same as in example 2, but the duration of the second part of the break is increased by 5 minutes (min_last_split_part_duration_s = 2700).

The first part (1 hour and 20 minutes) is split from the total break time. 40 minutes of the initial break remain. The second part must be split from the remaining 40 minutes, but min_last_split_part_duration_s = 2700 (45 minutes). The remaining time can't be negative, so the duration of the second part will be increased to 45 minutes to minimally comply with the condition min_last_split_part_duration_s = 2700.

As a result, the sum of the duration of the break parts will exceed the initially set duration by 5 minutes, amounting to 2 hours and 5 minutes (7500 seconds).

Breaks during order handling

"breaks": [
  {
    "can_rest_during_service": true,
    "rest_duration_s": 3000,
    "work_time_range_from_start": "1:30 - 2:00"
  },
  ...
]    

"locations": [
  {
    "id": 123,
    "can_have_rest_during_service": true,    
    "service_duration_s": 600,  
    ...
  }
]

By default, breaks can overlap with the handling time of an order or depot. In routes, these breaks are indicated before the order or depot. The start time arrival_time_s and end time departure_time_s of the break coincide with the arrival_time_s and departure_time_s of the order or depot. Inside this overall interval, the handling time duration is determined by the parameter service_duration_s. In the response for such an order or depot, the field is_after_service_work_break = true is added to indicate that handling starts after the break.

If can_rest_during_service = true, the break can be scheduled as the first location in the shift. For regular breaks that don't overlap with the handling time, this is impossible.

To prevent breaks from overlapping with the handling time, set can_have_rest_during_service to false for the order or depot and can_rest_during_service to false for the break.

Example 1

A 50-minute break should be scheduled 1.5 hours after the start of the route. There are 2 orders in the route, with a handling time of 1 hour and the parameter can_have_rest_during_service = true. The break overlaps with the handling time for the first order, for which the courier arrives 1 hour and 8 minutes after the start of the route and leaves 2 hours and 20 minutes later.

Example 2

The same as in example 1, but orders have the parameter can_have_rest_during_service = false. The break is scheduled at the first order's location, but before handling the order and too early: just 1 hour and 9 minutes after the start of the route.

Break chains

The rest_schedule can contain many independent breaks break chains. Each chain can contain many breaks with special conditions. The start of a break in every chain depends only on the built route. It doesn't depend on breaks in other chains.

The order of chains doesn't matter, but you must specify breaks in one chain sequentially.

If the route is completed before the stop (for example, the route is completed in 3 hours, and the stop is scheduled after 4 hours), all the unmade stops are reset.

Example

The route is built with 30-minute rest breaks after 4–4.5 hours of work. 15 hours after the start of the route, a sleep break is planned. As a result, a sleep break is scheduled 1.5 hours after a rest break.

Penalties

In some cases, RouteQ can plan routes that violate the rest window. To apply penalties for such violations, use the fields penalty.late and penalty.early. If the penalty is higher than the savings resulting from the window violation, the route is planned without violations.

Repeat conditions

Example 1

The courier delivers orders to a neighboring city and periodic breaks. Breaks are set every 60–80 minutes of the route (travel_time_range) using the repeat condition repeatable. As a result, the algorithm scheduled two breaks.

• One-hour lunch break.

Planned route

The user can specify which courier should deliver particular orders. This is useful:

• For additional planning when you have pre-planned routes.

• When the order requires a specific courier.

To specify pre-planned orders for the courier, use the vehicle.planned_route option. This option has the following properties:

• When planning, all orders that you specify in vehicle.planned_route can't become unassigned, even if strict restrictions are violated, such as vehicle capacity or time windows for which hard_window = true.

• By default, the order sequence set in planned_route isn't fixed. When re-planning, orders can be arranged in a new sequence.

• If you need to save the route that's specified in planned_route without saving changes (sequence changes and adding new orders), use vehicle.fixed_planned_route = true.

For each order in planned_route, be sure to specify the vehicle shift (even if the vehicle only has 1 shift).

If in planned_route several shifts are specified, you can lock orders for shifts using the fix_planned_shifts = true option. By default, the value is false.

If a courier arrives too early, delivery time of the order is determined by the vehicle.wait_if_early parameter:

• true: The courier waits for the order time window to start (default value).
• false: The courier handles the order as soon as they arrive.

If the courier needs to visit depots for reloading while following the route, specify them in the middle_depot_id field. They may be the same as the depots the courier visits at the start or at the end of the route.

If the courier needs to visit depots for reloading in planned_route, set is_middle_depot = true (it's false by default). If you set is_middle_depot = true for all depots, the algorithm will plan the start and end depots based on the courier settings (see sections Start from one of several depots and Returning to a depot at the end of the route or run).

Example 1

Both couriers had pre-planned orders in planned_route. As a result, these orders were given to these two couriers.

Example 2

This example involves 1 vehicle that has orders linked to it via planned_route. The total weight of the orders exceeds the vehicle capacity, but the route is still being planned (because orders specified in this option can't be unallocated). But the ask status is UNFEASIBLE.

Example 3

Theoretically, 2 couriers could deliver all 20 orders without overload and without being late. But a fixed sequence is specified for courier 1 using the vehicle.fixed_planned_route = true parameter, so they'll only deliver orders from this sequence. Courier 2 isn't limited by a strict plan, so they'll take as many orders as they can carry. Several orders will remain in the depot, despite the fact that courier 1 has the space and time.

Example 4.1

2 couriers need to deliver 15 orders in 2 shifts. Using the planned_route option, orders 1-8 are assigned to courier 1, and orders 9-15 to courier 2. At the same time, it's indicated that orders 1-4 and 9-12 must be delivered during the first shift, and orders 5-8 and 13-15 during the second shift. Since fix_planned_shifts = false and couriers manage to deliver all orders within one shift, the distribution of orders by shifts is not taken into account.

Example 4.2

The conditions are the same as in example 4.1, but the option fix_planned_shifts = true. This means the shifts during which orders have to be delivered are taken into account.

Loaded orders

If the order is already in the vehicle, the courier can immediately start delivery. To run this scenario, specify the parameters in the planned_route field:

* Specified for depots and orders of the garage type.

Example

Several orders were loaded in the courier's vehicle last night. The courier doesn't have to pick them up at the depot. Therefore, the point of the garage type is specified in the place where the courier will go.

The loaded_orders parameter shows that orders 1 and 2 have been loaded. The courier can immediately deliver them to the destination.

The following parameters are also set in the conditions:

• planned_runs_first = true.

• delivery_in_current_run = true for depot and garage.

The courier starts from the garage and immediately delivers orders 1 and 2. They then go to the depot to pick up orders 3 and 4, which they must deliver immediately after loading. After these two deliveries, the courier returns to the depot to pick up orders 5 and 6 and follows the route further.

Fixed part of the route

The visited_locations feature is useful if:

• The beginning of route must follow a particular path.

• You need to change the start point when doing additional planning.

The route must be fixed for each courier individually.

To do this, specify the visited_locations array in vehicles and describe the points of the fixed route using the following parameters.

* Required parameter

Example 1

There are 5 orders in this example. The sequence of orders 1, 2, 3 is fixed in visited_locations. Orders 4 and 5 can be delivered in any sequence.

Adjusting the vehicle's moving time

To calculate the speed of a vehicle when building a route, RouteQ uses Yandex Maps data about traffic and the speed factor specified in the request. Although trucks usually move slower in traffic jams, some drivers drive more aggressively and arrive earlier than the calculated timeframes.

To compensate for such deviations, RouteQ has the travel_time_multiplier option where you can specify a fractional value. If the value is 1, the calculation is made for the vehicle with the expected average speed. At smaller values (for example, 0.8), the calculation accounts for faster vehicles. At higher values (for example, 1.2), the calculation accounts for slower vehicles.

Example 1

In the example below, the routing request is sent without adjusting the transit time. As a result, the vehicle delivers the order in 4 hours and 20 minutes, with 3 hours and 40 minutes spent moving between the points.

API request (JSON) ⋅ API response ⋅ View on map

Example 2

The same as in example 1, but with the travel_time_multiplier parameter set to 0.5. In the resulting route, the courier delivers the order in 2 hours and 25 minutes, spending 1 hour and 45 minutes moving between the points. However, time spent on parking and handover remains unchanged.

Example 3

The same as in example 1, but with the travel_time_multiplier parameter set to 2. In the resulting route, the courier delivers the order in 7 hours and 58 minutes, spending 7 hours and 18 minutes moving between the points. Traveling the route takes more than twice as long as in example 1, because part of the route occurs at peak hours, and the vehicle can't drive at the maximum speed. Time spent on parking and handover remains unchanged.

Adjusting handling time

In addition to the overall handling time at a depot, the time a courier spends on order handover is also taken into account when calculating the total time spent on this order. Handover time includes parking, riding the elevator, handing over the delivery, and paperwork. This time is considered in the service_duration_s and shared_service_duration_s parameters. However, some couriers spend less time at depots at the route start and complete handovers faster than others. For example:

• In the case of parallel planning for vehicles and couriers using public transport, couriers who travel by public transport don't have to spend time parking. As a result, they need lower handling time.

• Some couriers are faster than others. Experienced couriers usually spend less time at depots and on order handovers.

To compensate for the difference in working time, RouteQ has the service_duration_multiplier and shared_service_duration_multiplier parameters that can be specified for couriers. These parameters affect the times a specific courier will spend at a depot and on handling an order. If the value is 1, the handling time matches the time specified in the service_duration or shared_service_duration field and the depot handling time equals the value specified in the service_duration_s parameter for the depot. If the value is less than 1, the handling time and the handling time at the depot are reduced. And if the value is greater than 1, these times are increased.

Example 1

In the example below, the routing request is sent without adjusting the handling time.

Example 2

In the example below, the same request is sent to RouteQ as in example 1, but with the service_duration_multiplier parameter set to 0.5. Order handling and handling time at the depot take half as much time compared to example 1.

Prompt delivery

To build an optimal route, the algorithm minimizes the wait time between route points. But there are cases when it's useful to shift delivery to an earlier time. For example:

• You have to minimize the risk of late arrival.
• It's more comfortable for the courier to travel in the daytime.

To deliver goods as early as possible, use the penalty.arrival_after_start penalty, which consists of two parameters:

• average_h: Sets the penalty amount for the average arrival time after the start of the time window. When using the option, we always recommend specifying this value.
• as_soon_as_possible: Determines whether to start the route as early as possible. The parameter takes the value true or false (by default). It is specified in addition to average_h.

If you don't use the penalty.arrival_after_start penalty, the route will be built with the minimal wait time between points and the latest possible start time from the depot.

When using the penalty, the algorithm will build routes to start them earlier, provided it doesn't reduce quality.

If the route must start as early as possible (even if it causes additional waiting), specify penalty.arrival_after_start.as_soon_as_possible = true.

Example 1

The route includes 4 orders with different time windows. The earliest start of the time window for order 5 is 08:00. The courier starts from the depot at 11:02 and arrives at the first delivery point at 11:40. Order 5 is delivered at 12:59.

Example 2

The same data is used as in example 1, but the penalty is set for the average arrival time after the start of the time window using the penalty.arrival_after_start.average_h parameter. The courier starts from the depot at 06:59, waits for 8 minutes, and then delivers the earliest order (order 5) at 08:00.

Trailers

A trailer is a truck with a trailer attached. Orders can be placed in both the truck and trailer. An order can be partially loaded in the truck and in the trailer.

To describe the trailer, use the trailer object.

Sample trailer description in a request:

{
    "trailer": {
        "capacity": {
            "weight_kg": 10000,
            "units": 200
        },
        "max_capacity_difference": {
            "units": 10,
            "weight_kg": 0
        },
        "cost": {
            "fixed": 1000,
            "km": 10
        },
        "decoupling_time_s": 300,
        "coupling_time_s": 300,
        "rolling_time": {
            "fixed_time_s": 3000
        }
    }
}
