Class Vehicle (1.2.0)

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

NameDescription
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 MutableSequence[str]
Specifies tags attached to the start of the vehicle's route. Empty or duplicate strings are not allowed.
end_tags MutableSequence[str]
Specifies tags attached to the end of the vehicle's route. Empty or duplicate strings are not allowed.
start_time_windows MutableSequence[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 MutableSequence[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 MutableMapping[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 MutableMapping[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 MutableSequence[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 MutableSequence[google.cloud.optimization_v1.types.CapacityQuantity]
Deprecated: Use [Vehicle.load_limits][] instead.
start_load_intervals MutableSequence[google.cloud.optimization_v1.types.CapacityQuantityInterval]
Deprecated: Use [Vehicle.LoadLimit.start_load_interval][] instead.
end_load_intervals MutableSequence[google.cloud.optimization_v1.types.CapacityQuantityInterval]
Deprecated: Use [Vehicle.LoadLimit.end_load_interval][] instead.

Classes

DurationLimit

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

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

The abstract base class for a message.

Parameters
NameDescription
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)
