Properties

transport

Returns the transport used by the client instance.

Returns
TypeDescription
FleetRoutingTransportThe transport used by the client instance.

Methods

FleetRoutingClient

FleetRoutingClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.optimization_v1.services.fleet_routing.transports.base.FleetRoutingTransport]] = None, client_options: Optional[Union[google.api_core.client_options.ClientOptions, dict]] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the fleet routing client.

Parameters
NameDescription
credentials Optional[google.auth.credentials.Credentials]

The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.

transport Union[str, FleetRoutingTransport]

The transport to use. If set to None, a transport is chosen automatically.

client_options Optional[Union[google.api_core.client_options.ClientOptions, dict]]

Custom options for the client. It won't take effect if a transport instance is provided. (1) The api_endpoint property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the api_endpoint property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the client_cert_source property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.

client_info google.api_core.gapic_v1.client_info.ClientInfo

The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions
TypeDescription
google.auth.exceptions.MutualTLSChannelErrorIf mutual TLS transport creation failed for any reason.

__exit__

__exit__(type, value, traceback)

Releases underlying transport's resources.

batch_optimize_tours

batch_optimize_tours(request: Optional[Union[google.cloud.optimization_v1.types.fleet_routing.BatchOptimizeToursRequest, dict]] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Union[float, object] = <_MethodDefault._DEFAULT_VALUE: <object object>>, metadata: Sequence[Tuple[str, str]] = ())

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 ShipmentRoute\ s, which are a set of routes to be performed by vehicles minimizing the overall cost.

Parameters
NameDescription
request Union[google.cloud.optimization_v1.types.BatchOptimizeToursRequest, dict]

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

A ShipmentModel model consists mainly of Shipment\ s that need to be carried out and Vehicle\ s that can be used to transport the Shipment\ s. The ShipmentRoute\ s assign Shipment\ s to Vehicle\ s. More specifically, they assign a series of Visit\ s 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 ShipmentRoute\ s to Vehicle\ s that minimizes the total cost where cost has many components defined in the ShipmentModel.
