Google Cloud Optimization V1 Client - Class FleetRoutingClient (0.1.9)

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

Service Description: A service for optimizing vehicle tours.

Validity of certain types of fields:

google.protobuf.Timestamp
Times are in Unix time: seconds since 1970-01-01T00:00:00+00:00.
seconds must be in [0, 253402300799], i.e. in [1970-01-01T00:00:00+00:00, 9999-12-31T23:59:59+00:00].
nanos must be unset or set to 0.
google.protobuf.Duration
seconds must be in [0, 253402300799], i.e. in [1970-01-01T00:00:00+00:00, 9999-12-31T23:59:59+00:00].
nanos must be unset or set to 0.
google.type.LatLng
latitude must be in [-90.0, 90.0].
longitude must be in [-180.0, 180.0].
at least one of latitude and longitude must be non-zero.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$fleetRoutingClient = new FleetRoutingClient();
try {
    $parent = 'parent';
    $modelConfigs = [];
    $operationResponse = $fleetRoutingClient->batchOptimizeTours($parent, $modelConfigs);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $fleetRoutingClient->batchOptimizeTours($parent, $modelConfigs);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $fleetRoutingClient->resumeOperation($operationName, 'batchOptimizeTours');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $fleetRoutingClient->close();
}

Methods

getOperationsClient

Return an OperationsClient object with the same endpoint as $this.

Returns
Type	Description
`Google\ApiCore\LongRunning\OperationsClient`

resumeOperation

Resume an existing long running operation that was previously started by a long running API method. If $methodName is not provided, or does not match a long running API method, then the operation can still be resumed, but the OperationResponse object will not deserialize the final response.

Parameters
Name	Description
`operationName`	`string` The name of the long running operation
`methodName`	`string` The name of the method used to start the operation

Returns
Type	Description
`Google\ApiCore\OperationResponse`

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

batchOptimizeTours

Optimizes vehicle tours for one or more OptimizeToursRequest messages as a batch.

This method is a Long Running Operation (LRO). The inputs for optimization (OptimizeToursRequest messages) and outputs (OptimizeToursResponse messages) are read/written from/to Cloud Storage in user-specified format. Like the OptimizeTours method, each OptimizeToursRequest contains a ShipmentModel and returns an OptimizeToursResponse containing ShipmentRoutes, which are a set of routes to be performed by vehicles minimizing the overall cost.

Parameters
Name	Description
`parent`	`string` Required. Target project and location to make a call. Format: `projects/{project-id}/locations/{location-id}`. If no location is specified, a region will be chosen automatically.
`modelConfigs`	`array<Google\Cloud\Optimization\V1\BatchOptimizeToursRequest\AsyncModelConfig>` Required. Input/Output information each purchase model, such as file paths and data formats.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns

optimizeTours

Sends an OptimizeToursRequest containing a ShipmentModel and returns an OptimizeToursResponse containing ShipmentRoutes, which are a set of routes to be performed by vehicles minimizing the overall cost.

A ShipmentModel model consists mainly of Shipments that need to be carried out and Vehicles that can be used to transport the Shipments. The ShipmentRoutes assign Shipments to Vehicles. More specifically, they assign a series of Visits to each vehicle, where a Visit corresponds to a VisitRequest, which is a pickup or delivery for a Shipment.

The goal is to provide an assignment of ShipmentRoutes to Vehicles that minimizes the total cost where cost has many components defined in the ShipmentModel.

Parameters
Name	Description
`parent`	`string` Required. Target project and location to make a call. Format: `projects/{project-id}/locations/{location-id}`. If no location is specified, a region will be chosen automatically.
`optionalArgs`	`array` Optional.
`↳ timeout`	`Duration` If this timeout is set, the server returns a response before the timeout period has elapsed or the server deadline for synchronous requests is reached, whichever is sooner. For asynchronous requests, the server will generate a solution (if possible) before the timeout has elapsed.
`↳ model`	`ShipmentModel` Shipment model to solve.
`↳ solvingMode`	`int` By default, the solving mode is `DEFAULT_SOLVE` (0). For allowed values, use constants defined on Google\Cloud\Optimization\V1\OptimizeToursRequest\SolvingMode
`↳ maxValidationErrors`	`int` Truncates the number of validation errors returned. These errors are typically attached to an INVALID_ARGUMENT error payload as a BadRequest error detail (https://cloud.google.com/apis/design/errors#error_details), unless solving_mode=VALIDATE_ONLY: see the OptimizeToursResponse.validation_errors field. This defaults to 100 and is capped at 10,000.
`↳ searchMode`	`int` Search mode used to solve the request. For allowed values, use constants defined on Google\Cloud\Optimization\V1\OptimizeToursRequest\SearchMode
`↳ injectedFirstSolutionRoutes`	`ShipmentRoute[]` Guide the optimization algorithm in finding a first solution that is similar to a previous solution. The model is constrained when the first solution is built. Any shipments not performed on a route are implicitly skipped in the first solution, but they may be performed in successive solutions. The solution must satisfy some basic validity assumptions: * for all routes, `vehicle_index` must be in range and not be duplicated. * for all visits, `shipment_index` and `visit_request_index` must be in range. * a shipment may only be referenced on one route. * the pickup of a pickup-delivery shipment must be performed before the delivery. * no more than one pickup alternative or delivery alternative of a shipment may be performed. * for all routes, times are increasing (i.e., `vehicle_start_time <= visits[0].start_time <= visits[1].start_time ... <= vehicle_end_time`). * a shipment may only be performed on a vehicle that is allowed. A vehicle is allowed if Shipment.allowed_vehicle_indices is empty or its `vehicle_index` is included in Shipment.allowed_vehicle_indices. If the injected solution is not feasible, a validation error is not necessarily returned and an error indicating infeasibility may be returned instead.
`↳ injectedSolutionConstraint`	`InjectedSolutionConstraint` Constrain the optimization algorithm to find a final solution that is similar to a previous solution. For example, this may be used to freeze portions of routes which have already been completed or which are to be completed but must not be modified. If the injected solution is not feasible, a validation error is not necessarily returned and an error indicating infeasibility may be returned instead.
`↳ refreshDetailsRoutes`	`ShipmentRoute[]` If non-empty, the given routes will be refreshed, without modifying their underlying sequence of visits or travel times: only other details will be updated. This does not solve the model. As of 2020/11, this only populates the polylines of non-empty routes and requires that `populate_polylines` is true. The `route_polyline` fields of the passed-in routes may be inconsistent with route `transitions`. This field must not be used together with `injected_first_solution_routes` or `injected_solution_constraint`. `Shipment.ignore` and `Vehicle.ignore` have no effect on the behavior. Polylines are still populated between all visits in all non-empty routes regardless of whether the related shipments or vehicles are ignored.
`↳ interpretInjectedSolutionsUsingLabels`	`bool` If true: * uses ShipmentRoute.vehicle_label instead of `vehicle_index` to match routes in an injected solution with vehicles in the request; reuses the mapping of original ShipmentRoute.vehicle_index to new ShipmentRoute.vehicle_index to update ConstraintRelaxation.vehicle_indices if non-empty, but the mapping must be unambiguous (i.e., multiple `ShipmentRoute`s must not share the same original `vehicle_index`). * uses ShipmentRoute.Visit.shipment_label instead of `shipment_index` to match visits in an injected solution with shipments in the request; * uses SkippedShipment.label instead of SkippedShipment.index to match skipped shipments in the injected solution with request shipments. This interpretation applies to the `injected_first_solution_routes`, `injected_solution_constraint`, and `refresh_details_routes` fields. It can be used when shipment or vehicle indices in the request have changed since the solution was created, perhaps because shipments or vehicles have been removed from or added to the request. If true, labels in the following categories must appear at most once in their category: * Vehicle.label in the request; * Shipment.label in the request; * ShipmentRoute.vehicle_label in the injected solution; * SkippedShipment.label and ShipmentRoute.Visit.shipment_label in the injected solution (except pickup/delivery visit pairs, whose `shipment_label` must appear twice). If a `vehicle_label` in the injected solution does not correspond to a request vehicle, the corresponding route is removed from the solution along with its visits. If a `shipment_label` in the injected solution does not correspond to a request shipment, the corresponding visit is removed from the solution. If a SkippedShipment.label in the injected solution does not correspond to a request shipment, the `SkippedShipment` is removed from the solution. Removing route visits or entire routes from an injected solution may have an effect on the implied constraints, which may lead to change in solution, validation errors, or infeasibility. NOTE: The caller must ensure that each Vehicle.label (resp. Shipment.label) uniquely identifies a vehicle (resp. shipment) entity used across the two relevant requests: the past request that produced the `OptimizeToursResponse` used in the injected solution and the current request that includes the injected solution. The uniqueness checks described above are not enough to guarantee this requirement.
`↳ considerRoadTraffic`	`bool` Consider traffic estimation in calculating `ShipmentRoute` fields Transition.travel_duration, Visit.start_time, and `vehicle_end_time`; in setting the ShipmentRoute.has_traffic_infeasibilities field, and in calculating the OptimizeToursResponse.total_cost field.
`↳ populatePolylines`	`bool` If true, polylines will be populated in response `ShipmentRoute`s.
`↳ populateTransitionPolylines`	`bool` If true, polylines will be populated in response ShipmentRoute.transitions. Note that in this case, the polylines will also be populated in the deprecated `travel_steps`.
`↳ allowLargeDeadlineDespiteInterruptionRisk`	`bool` If this is set, then the request can have a deadline (see https://grpc.io/blog/deadlines) of up to 60 minutes. Otherwise, the maximum deadline is only 30 minutes. Note that long-lived requests have a significantly larger (but still small) risk of interruption.
`↳ useGeodesicDistances`	`bool` If true, travel distances will be computed using geodesic distances instead of Google Maps distances, and travel times will be computed using geodesic distances with a speed defined by `geodesic_meters_per_second`.
`↳ geodesicMetersPerSecond`	`float` When `use_geodesic_distances` is true, this field must be set and defines the speed applied to compute travel times. Its value must be at least 1.0 meters/seconds.
`↳ label`	`string` Label that may be used to identify this request, reported back in the OptimizeToursResponse.request_label.
`↳ populateTravelStepPolylines`	`bool` Deprecated: Use OptimizeToursRequest.populate_transition_polylines instead. If true, polylines will be populated in response ShipmentRoute.transitions. Note that in this case, the polylines will also be populated in the deprecated `travel_steps`.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.
