Google Cloud Optimization V1 Client - Class Shipment (1.0.1)

Reference documentation and code samples for the Google Cloud Optimization V1 Client class Shipment.

The shipment of a single item, from one of its pickups to one of its deliveries. For the shipment to be considered as performed, a unique vehicle must visit one of its pickup locations (and decrease its spare capacities accordingly), then visit one of its delivery locations later on (and therefore re-increase its spare capacities accordingly).

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ pickups array<Shipment\VisitRequest>

Set of pickup alternatives associated to the shipment. If not specified, the vehicle only needs to visit a location corresponding to the deliveries.
↳ deliveries array<Shipment\VisitRequest>

Set of delivery alternatives associated to the shipment. If not specified, the vehicle only needs to visit a location corresponding to the pickups.
↳ load_demands array|Google\Protobuf\Internal\MapField

Load demands of the shipment (for example weight, volume, number of pallets etc). The keys in the map should be identifiers describing the type of the corresponding load, ideally also including the units. For example: "weight_kg", "volume_gallons", "pallet_count", etc. If a given key does not appear in the map, the corresponding load is considered as null.
↳ penalty_cost float

If the shipment is not completed, this penalty is added to the overall cost of the routes. A shipment is considered completed if one of its pickup and delivery alternatives is visited. The cost may be expressed in the same unit used for all other cost-related fields in the model and must be positive. IMPORTANT: If this penalty is not specified, it is considered infinite, i.e. the shipment must be completed.
↳ allowed_vehicle_indices array

The set of vehicles that may perform this shipment. If empty, all vehicles may perform it. Vehicles are given by their index in the ShipmentModel's vehicles list.
↳ costs_per_vehicle array

Specifies the cost that is incurred when this shipment is delivered by each vehicle. If specified, it must have EITHER: * * the same number of elements as costs_per_vehicle_indices. costs_per_vehicle[i] corresponds to vehicle costs_per_vehicle_indices[i] of the model. * * the same number of elements as there are vehicles in the model. The i-th element corresponds to vehicle #i of the model. These costs must be in the same unit as penalty_cost and must not be negative. Leave this field empty, if there are no such costs.
↳ costs_per_vehicle_indices array

Indices of the vehicles to which costs_per_vehicle applies. If non-empty, it must have the same number of elements as costs_per_vehicle. A vehicle index may not be specified more than once. If a vehicle is excluded from costs_per_vehicle_indices, its cost is zero.
↳ pickup_to_delivery_relative_detour_limit float

Specifies the maximum relative detour time compared to the shortest path from pickup to delivery. If specified, it must be nonnegative, and the shipment must contain at least a pickup and a delivery. For example, let t be the shortest time taken to go from the selected pickup alternative directly to the selected delivery alternative. Then setting pickup_to_delivery_relative_detour_limit enforces: start_time(delivery) - start_time(pickup) <= std::ceil(t * (1.0 + pickup_to_delivery_relative_detour_limit)) If both relative and absolute limits are specified on the same shipment, the more constraining limit is used for each possible pickup/delivery pair. As of 2017/10, detours are only supported when travel durations do not depend on vehicles.
↳ pickup_to_delivery_absolute_detour_limit Google\Protobuf\Duration

Specifies the maximum absolute detour time compared to the shortest path from pickup to delivery. If specified, it must be nonnegative, and the shipment must contain at least a pickup and a delivery. For example, let t be the shortest time taken to go from the selected pickup alternative directly to the selected delivery alternative. Then setting pickup_to_delivery_absolute_detour_limit enforces: start_time(delivery) - start_time(pickup) <= t + pickup_to_delivery_absolute_detour_limit If both relative and absolute limits are specified on the same shipment, the more constraining limit is used for each possible pickup/delivery pair. As of 2017/10, detours are only supported when travel durations do not depend on vehicles.
↳ pickup_to_delivery_time_limit Google\Protobuf\Duration

Specifies the maximum duration from start of pickup to start of delivery of a shipment. If specified, it must be nonnegative, and the shipment must contain at least a pickup and a delivery. This does not depend on which alternatives are selected for pickup and delivery, nor on vehicle speed. This can be specified alongside maximum detour constraints: the solution will respect both specifications.
↳ shipment_type string

Non-empty string specifying a "type" for this shipment. This feature can be used to define incompatibilities or requirements between shipment_types (see shipment_type_incompatibilities and shipment_type_requirements in ShipmentModel). Differs from visit_types which is specified for a single visit: All pickup/deliveries belonging to the same shipment share the same shipment_type.
↳ label string

Specifies a label for this shipment. This label is reported in the response in the shipment_label of the corresponding ShipmentRoute.Visit.
↳ ignore bool

If true, skip this shipment, but don't apply a penalty_cost. Ignoring a shipment results in a validation error when there are any shipment_type_requirements in the model. Ignoring a shipment that is performed in injected_first_solution_routes or injected_solution_constraint is permitted; the solver removes the related pickup/delivery visits from the performing route. precedence_rules that reference ignored shipments will also be ignored.
↳ demands array<CapacityQuantity>

Deprecated: Use Shipment.load_demands instead.
