Google Maps Route Optimization V1 Client - Class ShipmentModel (0.2.0)

Reference documentation and code samples for the Google Maps Route Optimization V1 Client class ShipmentModel.

A shipment model contains a set of shipments which must be performed by a set of vehicles, while minimizing the overall cost, which is the sum of:

• the cost of routing the vehicles (sum of cost per total time, cost per travel time, and fixed cost over all vehicles).

• the unperformed shipment penalties.

• the cost of the global duration of the shipments

Constructor.

Set of shipments which must be performed in the model.

Set of shipments which must be performed in the model.

Set of vehicles which can be used to perform visits.

Set of vehicles which can be used to perform visits.

Constrains the maximum number of active vehicles. A vehicle is active if its route performs at least one shipment. This can be used to limit the number of routes in the case where there are fewer drivers than vehicles and that the fleet of vehicles is heterogeneous. The optimization will then select the best subset of vehicles to use.

Must be strictly positive.

Global start and end time of the model: no times outside of this range can be considered valid.

The model's time span must be less than a year, i.e. the global_end_time and the global_start_time must be within 31536000 seconds of each other. When using cost_per_*hour fields, you might want to set this window to a smaller interval to increase performance (eg. if you model a single day, you should set the global time limits to that day). If unset, 00:00:00 UTC, January 1, 1970 (i.e. seconds: 0, nanos: 0) is used as default.

The "global duration" of the overall plan is the difference between the earliest effective start time and the latest effective end time of all vehicles. Users can assign a cost per hour to that quantity to try and optimize for earliest job completion, for example. This cost must be in the same unit as Shipment.penalty_cost.

Specifies duration and distance matrices used in the model. If this field is empty, Google Maps or geodesic distances will be used instead, depending on the value of the use_geodesic_distances field. If it is not empty, use_geodesic_distances cannot be true and neither duration_distance_matrix_src_tags nor duration_distance_matrix_dst_tags can be empty.

Usage examples:

• There are two locations: locA and locB.
• 1 vehicle starting its route at locA and ending it at locA.
• 1 pickup visit request at locB. php model { vehicles { start_tags: "locA" end_tags: "locA" } shipments { pickups { tags: "locB" } } duration_distance_matrix_src_tags: "locA" duration_distance_matrix_src_tags: "locB" duration_distance_matrix_dst_tags: "locA" duration_distance_matrix_dst_tags: "locB" duration_distance_matrices { rows { # from: locA durations { seconds: 0 } meters: 0 # to: locA durations { seconds: 100 } meters: 1000 # to: locB } rows { # from: locB durations { seconds: 102 } meters: 990 # to: locA durations { seconds: 0 } meters: 0 # to: locB } } }
• There are three locations: locA, locB and locC.
• 1 vehicle starting its route at locA and ending it at locB, using matrix "fast".
• 1 vehicle starting its route at locB and ending it at locB, using matrix "slow".
