Class Vehicle (1.0.1)

Vehicle(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Models a vehicle in a shipment problem. Solving a shipment problem will build a route starting from start_location and ending at end_location for this vehicle. A route is a sequence of visits (see ShipmentRoute).

Attributes
Name	Description
`travel_mode`	`google.cloud.optimization_v1.types.Vehicle.TravelMode` The travel mode which affects the roads usable by the vehicle and its speed. See also `travel_duration_multiple`.
`start_location`	`google.type.latlng_pb2.LatLng` Geographic location where the vehicle starts before picking up any shipments. If not specified, the vehicle starts at its first pickup. If the shipment model has duration and distance matrices, `start_location` must not be specified.
`start_waypoint`	`google.cloud.optimization_v1.types.Waypoint` Waypoint representing a geographic location where the vehicle starts before picking up any shipments. If neither `start_waypoint` nor `start_location` is specified, the vehicle starts at its first pickup. If the shipment model has duration and distance matrices, `start_waypoint` must not be specified.
`end_location`	`google.type.latlng_pb2.LatLng` Geographic location where the vehicle ends after it has completed its last `VisitRequest`. If not specified the vehicle's `ShipmentRoute` ends immediately when it completes its last `VisitRequest`. If the shipment model has duration and distance matrices, `end_location` must not be specified.
`end_waypoint`	`google.cloud.optimization_v1.types.Waypoint` Waypoint representing a geographic location where the vehicle ends after it has completed its last `VisitRequest`. If neither `end_waypoint` nor `end_location` is specified, the vehicle's `ShipmentRoute` ends immediately when it completes its last `VisitRequest`. If the shipment model has duration and distance matrices, `end_waypoint` must not be specified.
`start_tags`	`Sequence[str]` Specifies tags attached to the start of the vehicle's route. Empty or duplicate strings are not allowed.
`end_tags`	`Sequence[str]` Specifies tags attached to the end of the vehicle's route. Empty or duplicate strings are not allowed.
`start_time_windows`	`Sequence[google.cloud.optimization_v1.types.TimeWindow]` Time windows during which the vehicle may depart its start location. They must be within the global time limits (see [ShipmentModel.global_*][google.cloud.optimization.v1.ShipmentModel.global_start_time] fields). If unspecified, there is no limitation besides those global time limits. Time windows belonging to the same repeated field must be disjoint, i.e. no time window can overlap with or be adjacent to another, and they must be in chronological order. `cost_per_hour_after_soft_end_time` and `soft_end_time` can only be set if there is a single time window.
`end_time_windows`	`Sequence[google.cloud.optimization_v1.types.TimeWindow]` Time windows during which the vehicle may arrive at its end location. They must be within the global time limits (see [ShipmentModel.global_*][google.cloud.optimization.v1.ShipmentModel.global_start_time] fields). If unspecified, there is no limitation besides those global time limits. Time windows belonging to the same repeated field must be disjoint, i.e. no time window can overlap with or be adjacent to another, and they must be in chronological order. `cost_per_hour_after_soft_end_time` and `soft_end_time` can only be set if there is a single time window.
`travel_duration_multiple`	`float` Specifies a multiplicative factor that can be used to increase or decrease travel times of this vehicle. For example, setting this to 2.0 means that this vehicle is slower and has travel times that are twice what they are for standard vehicles. This multiple does not affect visit durations. It does affect cost if `cost_per_hour` or `cost_per_traveled_hour` are specified. This must be in the range [0.001, 1000.0]. If unset, the vehicle is standard, and this multiple is considered 1.0. WARNING: Travel times will be rounded to the nearest second after this multiple is applied but before performing any numerical operations, thus, a small multiple may result in a loss of precision. See also `extra_visit_duration_for_visit_type` below. This field is a member of `oneof`_ `_travel_duration_multiple`.
`unloading_policy`	`google.cloud.optimization_v1.types.Vehicle.UnloadingPolicy` Unloading policy enforced on the vehicle.
`load_limits`	`Mapping[str, google.cloud.optimization_v1.types.Vehicle.LoadLimit]` Capacities of the vehicle (weight, volume, # of pallets for example). The keys in the map are the identifiers of the type of load, consistent with the keys of the Shipment.load_demands field. If a given key is absent from this map, the corresponding capacity is considered to be limitless.
`cost_per_hour`	`float` Vehicle costs: all costs add up and must be in the same unit as Shipment.penalty_cost. Cost per hour of the vehicle route. This cost is applied to the total time taken by the route, and includes travel time, waiting time, and visit time. Using `cost_per_hour` instead of just `cost_per_traveled_hour` may result in additional latency.
`cost_per_traveled_hour`	`float` Cost per traveled hour of the vehicle route. This cost is applied only to travel time taken by the route (i.e., that reported in ShipmentRoute.transitions), and excludes waiting time and visit time.
`cost_per_kilometer`	`float` Cost per kilometer of the vehicle route. This cost is applied to the distance reported in the ShipmentRoute.transitions and does not apply to any distance implicitly traveled from the `arrival_location` to the `departure_location` of a single `VisitRequest`.
`fixed_cost`	`float` Fixed cost applied if this vehicle is used to handle a shipment.
`used_if_route_is_empty`	`bool` This field only applies to vehicles when their route does not serve any shipments. It indicates if the vehicle should be considered as used or not in this case. If true, the vehicle goes from its start to its end location even if it doesn't serve any shipments, and time and distance costs resulting from its start --> end travel are taken into account. Otherwise, it doesn't travel from its start to its end location, and no `break_rule` or delay (from `TransitionAttributes`) are scheduled for this vehicle. In this case, the vehicle's `ShipmentRoute` doesn't contain any information except for the vehicle index and label.
`route_duration_limit`	`google.cloud.optimization_v1.types.Vehicle.DurationLimit` Limit applied to the total duration of the vehicle's route. In a given `OptimizeToursResponse`, the route duration of a vehicle is the difference between its `vehicle_end_time` and `vehicle_start_time`.
`travel_duration_limit`	`google.cloud.optimization_v1.types.Vehicle.DurationLimit` Limit applied to the travel duration of the vehicle's route. In a given `OptimizeToursResponse`, the route travel duration is the sum of all its transitions.travel_duration.
`route_distance_limit`	`google.cloud.optimization_v1.types.DistanceLimit` Limit applied to the total distance of the vehicle's route. In a given `OptimizeToursResponse`, the route distance is the sum of all its transitions.travel_distance_meters.
`extra_visit_duration_for_visit_type`	`Mapping[str, google.protobuf.duration_pb2.Duration]` Specifies a map from visit_types strings to durations. The duration is time in addition to VisitRequest.duration to be taken at visits with the specified `visit_types`. This extra visit duration adds cost if `cost_per_hour` is specified. Keys (i.e. `visit_types`) cannot be empty strings. If a visit request has multiple types, a duration will be added for each type in the map.
`break_rule`	`google.cloud.optimization_v1.types.BreakRule` Describes the break schedule to be enforced on this vehicle. If empty, no breaks will be scheduled for this vehicle.
`label`	`str` Specifies a label for this vehicle. This label is reported in the response as the `vehicle_label` of the corresponding ShipmentRoute.
`ignore`	`bool` If true, `used_if_route_is_empty` must be false, and this vehicle will remain unused. If a shipment is performed by an ignored vehicle in `injected_first_solution_routes`, it is skipped in the first solution but is free to be performed in the response. If a shipment is performed by an ignored vehicle in `injected_solution_constraint` and any related pickup/delivery is constrained to remain on the vehicle (i.e., not relaxed to level `RELAX_ALL_AFTER_THRESHOLD`), it is skipped in the response. If a shipment has a non-empty `allowed_vehicle_indices` field and all of the allowed vehicles are ignored, it is skipped in the response.
`break_rule_indices`	`Sequence[int]` Deprecated: No longer used. Indices in the `break_rule` field in the source [ShipmentModel][]. They correspond to break rules enforced on the vehicle. As of 2018/03, at most one rule index per vehicle can be specified.
`capacities`	`Sequence[google.cloud.optimization_v1.types.CapacityQuantity]` Deprecated: Use [Vehicle.load_limits][] instead.
`start_load_intervals`	`Sequence[google.cloud.optimization_v1.types.CapacityQuantityInterval]` Deprecated: Use [Vehicle.LoadLimit.start_load_interval][] instead.
`end_load_intervals`	`Sequence[google.cloud.optimization_v1.types.CapacityQuantityInterval]` Deprecated: Use [Vehicle.LoadLimit.end_load_interval][] instead.

Classes

DurationLimit

DurationLimit(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A limit defining a maximum duration of the route of a vehicle. It can be either hard or soft.

When a soft limit field is defined, both the soft max threshold and its associated cost must be defined together.

ExtraVisitDurationForVisitTypeEntry

ExtraVisitDurationForVisitTypeEntry(
    mapping=None, *, ignore_unknown_fields=False, **kwargs
)

The abstract base class for a message.

Parameters
Name	Description
`kwargs`	`dict` Keys and values corresponding to the fields of the message.
`mapping`	`Union[dict, .Message]` A dictionary or message to be used to determine the values for this message.
`ignore_unknown_fields`	`Optional(bool)` If True, do not raise errors for unknown fields. Only applied if `mapping` is a mapping type or there are keyword parameters.

LoadLimit

LoadLimit(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Defines a load limit applying to a vehicle, e.g. "this truck may only carry up to 3500 kg". See load_limits.

LoadLimitsEntry

LoadLimitsEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The abstract base class for a message.

Parameters
Name	Description
`kwargs`	`dict` Keys and values corresponding to the fields of the message.
`mapping`	`Union[dict, .Message]` A dictionary or message to be used to determine the values for this message.

TravelMode

TravelMode(value)

Travel modes which can be used by vehicles.

These should be a subset of the Google Maps Platform Routes Preferred API travel modes, see: https://developers.google.com/maps/documentation/routes_preferred/reference/rest/Shared.Types/RouteTravelMode.

UnloadingPolicy

UnloadingPolicy(value)

Policy on how a vehicle can be unloaded. Applies only to shipments having both a pickup and a delivery.

Other shipments are free to occur anywhere on the route independent of unloading_policy.
