Cloud Fleet Routing service is under specific service terms. See Service specific terms.

OptimizeToursResponse

Response after solving a tour optimization problem containing the routes followed by each vehicle, the shipments which have been skipped and the overall cost of the solution.

Fields
routes[]

object (ShipmentRoute)

Routes computed for each vehicle; the i-th route corresponds to the i-th vehicle in the model.

requestLabel

string

Copy of the OptimizeToursRequest.label, if a label was specified in the request.

skippedShipments[]

object (SkippedShipment)

The list of all shipments skipped.

validationErrors[]

object (OptimizeToursValidationError)

List of all the validation errors that we were able to detect independently. See the "MULTIPLE ERRORS" explanation for the OptimizeToursValidationError message.

metrics

object (Metrics)

Duration, distance and usage metrics for this solution.

totalCost
(deprecated)

number

Deprecated: Use Metrics.total_cost instead. Total cost of the solution. This takes into account all costs: costs per per hour and travel hour, fixed vehicle costs, unperformed shipment penalty costs, global duration cost, etc.

OptimizeToursValidationError

Describes an error encountered when validating an OptimizeToursRequest.

Fields
code

integer

A validation error is defined by the pair (code, displayName) which are always present.

Other fields (below) provide more context about the error.

MULTIPLE ERRORS: When there are multiple errors, the validation process tries to output several of them. Much like a compiler, this is an imperfect process. Some validation errors will be "fatal", meaning that they stop the entire validation process. This is the case for displayName="UNSPECIFIED" errors, among others. Some may cause the validation process to skip other errors.

STABILITY: code and displayName should be very stable. But new codes and display names may appear over time, which may cause a given (invalid) request to yield a different (code, displayName) pair because the new error hid the old one (see "MULTIPLE ERRORS").

displayName

string

The error display name.

fields[]

object (FieldReference)

An error context may involve 0, 1 (most of the time) or more fields. For example, referring to vehicle #4 and shipment #2's first pickup can be done as follows:

fields { name: "vehicles" index: 4}
fields { name: "shipments" index: 2 subField {name: "pickups" index: 0} }

Note, however, that the cardinality of fields should not change for a given error code.

errorMessage

string

Human-readable string describing the error. There is a 1:1 mapping between code and errorMessage (when code != "UNSPECIFIED").

STABILITY: Not stable: the error message associated to a given code may change (hopefully to clarify it) over time. Please rely on the displayName and code instead.

offendingValues

string

May contain the value(s) of the field(s). This is not always available. You should absolutely not rely on it and use it only for manual model debugging.

FieldReference

Specifies a context for the validation error. A FieldReference always refers to a given field in this file and follows the same hierarchical structure. For example, we may specify element #2 of startTimeWindows of vehicle #5 using:

name: "vehicles" index: 5 subField { name: "endTimeWindows" index: 2 }

We however omit top-level entities such as OptimizeToursRequest or ShipmentModel to avoid crowding the message.

JSON representation

  // Union field index_or_key can be only one of the following:
  "index": integer,
  "key": string
  // End of list of possible types for union field index_or_key.
}
Fields
name

string

Name of the field, e.g., "vehicles".

subField

object (FieldReference)

Recursively nested sub-field, if needed.

Union field index_or_key.

index_or_key can be only one of the following:

index

integer

Index of the field if repeated.

key

string

Key if the field is a map.

Metrics

Overall metrics, aggregated over all routes.

JSON representation

  "aggregatedRouteMetrics": {
    object (AggregatedMetrics)
  },
  "skippedMandatoryShipmentCount": integer,
  "usedVehicleCount": integer,
  "earliestVehicleStartTime": string,
  "latestVehicleEndTime": string,
  "costs": {
    string: number,
    ...
  },
  "totalCost": number
}
Fields
aggregatedRouteMetrics

object (AggregatedMetrics)

Aggregated over the routes. Each metric is the sum (or max, for loads) over all ShipmentRoute.metrics fields of the same name.

skippedMandatoryShipmentCount

integer

Number of mandatory shipments skipped.

usedVehicleCount

integer

Number of vehicles used. Note: if a vehicle route is empty and Vehicle.used_if_route_is_empty is true, the vehicle is considered used.

earliestVehicleStartTime

string (Timestamp format)

The earliest start time for a used vehicle, computed as the minimum over all used vehicles of ShipmentRoute.vehicle_start_time.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

latestVehicleEndTime

string (Timestamp format)

The latest end time for a used vehicle, computed as the maximum over all used vehicles of ShipmentRoute.vehicle_end_time.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

costs

map (key: string, value: number)

Cost of the solution, broken down by cost-related request fields. The keys are proto paths, relative to the input OptimizeToursRequest, e.g. "model.shipments.pickups.cost", and the values are the total cost generated by the corresponding cost field, aggregated over the whole solution. In other words, costs["model.shipments.pickups.cost"] is the sum of all pickup costs over the solution. All costs defined in the model are reported in detail here with the exception of costs related to TransitionAttributes that are only reported in an aggregated way as of 2022/01.

totalCost

number

Total cost of the solution. The sum of all values in the costs map.
