BreakRule

Rules to generate time breaks for a vehicle (e.g. lunch breaks). A break is a contiguous period of time during which the vehicle remains idle at its current position and cannot perform any visit. A break may occur:

  • during the travel between two visits (which includes the time right before or right after a visit, but not in the middle of a visit), in which case it extends the corresponding transit time between the visits,
  • or before the vehicle start (the vehicle may not start in the middle of a break), in which case it does not affect the vehicle start time.
  • or after the vehicle end (ditto, with the vehicle end time).

Protobuf type google.cloud.optimization.v1.BreakRule

BreakRule.BreakRequest

The sequence of breaks (i.e. their number and order) that apply to each vehicle must be known beforehand. The repeated BreakRequests define that sequence, in the order in which they must occur. Their time windows (earliest_start_time / latest_start_time) may overlap, but they must be compatible with the order (this is checked).

Protobuf type google.cloud.optimization.v1.BreakRule

BreakRule.FrequencyConstraint

One may further constrain the frequency and duration of the breaks specified above, by enforcing a minimum break frequency, such as "There must be a break of at least 1 hour every 12 hours". Assuming that this can be interpreted as "Within any sliding time window of 12h, there must be at least one break of at least one hour", that example would translate to the following FrequencyConstraint: <code><code> { min_break_duration { seconds: 3600 } # 1 hour. max_inter_break_duration { seconds: 39600 } # 11 hours (12 - 1 = 11). } </code></code><code> The timing and duration of the breaks in the solution will respect all such constraints, in addition to the time windows and minimum durations already specified in the </code>BreakRequest<code>. A </code>FrequencyConstraint<code> may in practice apply to non-consecutive breaks. For example, the following schedule honors the "1h every 12h" example: </code><code><code> 04:00 vehicle start .. performing travel and visits .. 09:00 1 hour break 10:00 end of the break .. performing travel and visits .. 12:00 20-min lunch break 12:20 end of the break .. performing travel and visits .. 21:00 1 hour break 22:00 end of the break .. performing travel and visits .. 23:59 vehicle end </code></code>

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:


 try (FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create()) {
   OptimizeToursRequest request =
       OptimizeToursRequest.newBuilder()
           .setParent("parent-995424086")
           .setTimeout(Duration.newBuilder().build())
           .setModel(ShipmentModel.newBuilder().build())
           .setMaxValidationErrors(-1367418922)
           .addAllInjectedFirstSolutionRoutes(new ArrayList<ShipmentRoute>())
           .setInjectedSolutionConstraint(InjectedSolutionConstraint.newBuilder().build())
           .addAllRefreshDetailsRoutes(new ArrayList<ShipmentRoute>())
           .setInterpretInjectedSolutionsUsingLabels(true)
           .setConsiderRoadTraffic(true)
           .setPopulatePolylines(true)
           .setPopulateTransitionPolylines(true)
           .setAllowLargeDeadlineDespiteInterruptionRisk(true)
           .setUseGeodesicDistances(true)
           .setGeodesicMetersPerSecond(-2129658905)
           .setLabel("label102727412")
           .setPopulateTravelStepPolylines(true)
           .build();
   OptimizeToursResponse response = fleetRoutingClient.optimizeTours(request);
 }

Note: close() needs to be called on the FleetRoutingClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

  1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
  2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
  3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of FleetRoutingSettings to create(). For example:

To customize credentials:


 FleetRoutingSettings fleetRoutingSettings =
     FleetRoutingSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create(fleetRoutingSettings);

To customize the endpoint:


 FleetRoutingSettings fleetRoutingSettings =
     FleetRoutingSettings.newBuilder().setEndpoint(myEndpoint).build();
 FleetRoutingClient fleetRoutingClient = FleetRoutingClient.create(fleetRoutingSettings);

Please refer to the GitHub repository's samples for more quickstart code snippets.

FleetRoutingProto

FleetRoutingSettings

Settings class to configure an instance of FleetRoutingClient.

The default instance has everything set to sensible defaults:

  • The default service address (cloudoptimization.googleapis.com) and default port (443) are used.
  • Credentials are acquired automatically through Application Default Credentials.
  • Retries are configured for idempotent methods but not for non-idempotent methods.

The builder of this class is recursive, so contained classes are themselves builders. When build() is called, the tree of builders is called to create the complete settings object.

For example, to set the total timeout of optimizeTours to 30 seconds:


 FleetRoutingSettings.Builder fleetRoutingSettingsBuilder = FleetRoutingSettings.newBuilder();
 fleetRoutingSettingsBuilder
     .optimizeToursSettings()
     .setRetrySettings(
         fleetRoutingSettingsBuilder
             .optimizeToursSettings()
             .getRetrySettings()
             .toBuilder()
             .setTotalTimeout(Duration.ofSeconds(30))
             .build());
 FleetRoutingSettings fleetRoutingSettings = fleetRoutingSettingsBuilder.build();

Protobuf type google.cloud.optimization.v1.InjectedSolutionConstraint

InjectedSolutionConstraint.ConstraintRelaxation

For a group of vehicles, specifies at what threshold(s) constraints on visits will be relaxed and to which level. Shipments listed in the skipped_shipment field are constrained to be skipped; i.e., they cannot be performed.

Protobuf type google.cloud.optimization.v1.InjectedSolutionConstraint.ConstraintRelaxation

InjectedSolutionConstraint.ConstraintRelaxation.Builder

For a group of vehicles, specifies at what threshold(s) constraints on visits will be relaxed and to which level. Shipments listed in the skipped_shipment field are constrained to be skipped; i.e., they cannot be performed.

Protobuf type google.cloud.optimization.v1.InjectedSolutionConstraint.ConstraintRelaxation

InjectedSolutionConstraint.ConstraintRelaxation.Relaxation

If relaxations is empty, the start time and sequence of all visits on routes are fully constrained and no new visits may be inserted or added to those routes. Also, a vehicle's start and end time in routes is fully constrained, unless the vehicle is empty (i.e., has no visits and has used_if_route_is_empty set to false in the model). relaxations(i).level specifies the constraint relaxation level applied to a visit #j that satisfies:

  • route.visits(j).start_time >= relaxations(i).threshold_time AND
  • j + 1 >= relaxations(i).threshold_visit_count Similarly, the vehicle start is relaxed to relaxations(i).level if it satisfies:
  • vehicle_start_time >= relaxations(i).threshold_time AND
  • relaxations(i).threshold_visit_count == 0 and the vehicle end is relaxed to relaxations(i).level if it satisfies:
  • vehicle_end_time >= relaxations(i).threshold_time AND
  • route.visits_size() + 1 >= relaxations(i).threshold_visit_count To apply a relaxation level if a visit meets the threshold_visit_count OR the threshold_time add two relaxations with the same level: one with only threshold_visit_count set and the other with only threshold_time set. If a visit satisfies the conditions of multiple relaxations, the most relaxed level applies. As a result, from the vehicle start through the route visits in order to the vehicle end, the relaxation level becomes more relaxed: i.e., the relaxation level is non-decreasing as the route progresses. The timing and sequence of route visits that do not satisfy the threshold conditions of any relaxations are fully constrained and no visits may be inserted into these sequences. Also, if a vehicle start or end does not satisfy the conditions of any relaxation the time is fixed, unless the vehicle is empty.

Shipment

The shipment of a single item, from one of its pickups to one of its deliveries. For the shipment to be considered as performed, a unique vehicle must visit one of its pickup locations (and decrease its spare capacities accordingly), then visit one of its delivery locations later on (and therefore re-increase its spare capacities accordingly).

ShipmentModel

A shipment model contains a set of shipments which must be performed by a set of vehicles, while minimizing the overall cost, which is the sum of:

  • the cost of routing the vehicles (sum of cost per total time, cost per travel time, and fixed cost over all vehicles).
  • the unperformed shipment penalties.

ShipmentModel.BreakRule

Deprecated: Use top level [BreakRule][] instead. Rules to generate time breaks for a vehicle (e.g. lunch breaks). A break is a contiguous period of time during which the vehicle remains idle at its current position and cannot perform any visit. A break may occur:

  • during the travel between two visits (which includes the time right before or right after a visit, but not in the middle of a visit), in which case it extends the corresponding transit time between the visits,
  • or before the vehicle start (the vehicle may not start in the middle of a break), in which case it does not affect the vehicle start time.
  • or after the vehicle end (ditto, with the vehicle end time).

ShipmentModel.BreakRule.FrequencyConstraint

One may further constrain the frequency and duration of the breaks specified above, by enforcing a minimum break frequency, such as "There must be a break of at least 1 hour every 12 hours". Assuming that this can be interpreted as "Within any sliding time window of 12h, there must be at least one break of at least one hour", that example would translate to the following FrequencyConstraint: <code><code> { min_break_duration { seconds: 3600 } # 1 hour. max_inter_break_duration { seconds: 39600 } # 11 hours (12 - 1 = 11). } </code></code><code> The timing and duration of the breaks in the solution will respect all such constraints, in addition to the time windows and minimum durations already specified in the </code>BreakRequest<code>. A </code>FrequencyConstraint<code> may in practice apply to non-consecutive breaks. For example, the following schedule honors the "1h every 12h" example: </code><code><code> 04:00 vehicle start .. performing travel and visits .. 09:00 1 hour break 10:00 end of the break .. performing travel and visits .. 12:00 20-min lunch break 12:20 end of the break .. performing travel and visits .. 21:00 1 hour break 22:00 end of the break .. performing travel and visits .. 23:59 vehicle end </code></code>

ShipmentRoute

A vehicle's route can be decomposed, along the time axis, like this (we assume there are n visits): ` | | | | | T[2], | | | | Transition | Visit #0 | | | V[2], | | | | #0 | aka | T[1] | V[1] | ... | V[n-1] | T[n] | | aka T[0] | V[0] | | | V[n-2],| | | | | | | | T[n-1] | | | ^ ^ ^ ^ ^ ^ ^ ^ vehicle V[0].start V[0].end V[1]. V[1]. V[n]. V[n]. vehicle start (arrival) (departure) start end start end end Note that we make a difference between:

  • "punctual events", such as the vehicle start and end and each visit's start and end (aka arrival and departure). They happen at a given second.
  • "time intervals", such as the visits themselves, and the transition between visits. Though time intervals can sometimes have zero duration, i.e. start and end at the same second, they often have a positive duration. Invariants:
  • If there are n visits, there are n+1 transitions.
  • A visit is always surrounded by a transition before it (same index) and a transition after it (index + 1).
  • The vehicle start is always followed by transition #0.
  • The vehicle end is always preceded by transition #n. Zooming in, here is what happens during a
Transition and a Visit: ---+-------------------------------------+-----------------------------+--> | TRANSITION[i] | VISIT[i] | | | | | * TRAVEL: the vehicle moves from | PERFORM the visit: | | VISIT[i-1].departure_location to | | | VISIT[i].arrival_location, which | * Spend some time: | | takes a given travel duration | the "visit duration". | | and distance | | | | * Load or unload | | * BREAKS: the driver may have | some quantities from the | | breaks (e.g. lunch break). | vehicle: the "demand". | | | | | * WAIT: the driver/vehicle does | | | nothing. This can happen for | | | many reasons, for example when | | | the vehicle reaches the next | | | event's destination before the | | | start of its time window | | | | | | * DELAY: right before the next | | | arrival. E.g. the vehicle and/or | | | driver spends time unloading. | | | | | ---+-------------------------------------+-----------------------------+--> ^ ^ ^ V[i-1].end V[i].start V[i].end Lastly, here is how the TRAVEL, BREAKS, DELAY and WAIT can be arranged during a transition.
  • They don't overlap.
  • The DELAY is unique and must be a contiguous period of time right before the next visit (or vehicle end). Thus, it suffice to know the delay duration to know its start and end time.
  • The BREAKS are contiguous, non-overlapping periods of time. The response specifies the start time and duration of each break.
  • TRAVEL and WAIT are "preemptable": they can be interrupted several times during this transition. Clients can assume that travel happens "as soon as possible" and that "wait" fills the remaining time. A (complex) example:
    • TRANSITION[i] --++-----+-----------------------------------------------------------++--> || | | | | | | || || T | B | T | | B | | D || || r | r | r | W | r | W | e || || a | e | a | a | e | a | l || || v | a | v | i | a | i | a || || e | k | e | t | k | t | y || || l | | l | | | | || || | | | | | | || --++-----------------------------------------------------------------++--> `

    Enums

    AsyncModelMetadata.State

    Possible states of the operation.

    Protobuf enum google.cloud.optimization.v1.AsyncModelMetadata.State

    DataFormat

    Data formats for input and output files.

    Protobuf enum google.cloud.optimization.v1.DataFormat

    InjectedSolutionConstraint.ConstraintRelaxation.Relaxation.Level

    Expresses the different constraint relaxation levels, which are applied for a visit and those that follow when it satifies the threshold conditions. The enumeration below is in order of increasing relaxation.

    Protobuf enum google.cloud.optimization.v1.InjectedSolutionConstraint.ConstraintRelaxation.Relaxation.Level

    InputConfig.SourceCase

    OptimizeToursRequest.SearchMode

    Mode defining the behavior of the search, trading off latency versus solution quality. In all modes, the global request deadline is enforced.

    Protobuf enum google.cloud.optimization.v1.OptimizeToursRequest.SearchMode

    OptimizeToursRequest.SolvingMode

    Defines how the solver should handle the request. In all modes but VALIDATE_ONLY, if the request is invalid, you will receive an INVALID_REQUEST error. See max_validation_errors to cap the number of errors returned.

    Protobuf enum google.cloud.optimization.v1.OptimizeToursRequest.SolvingMode

    OptimizeToursValidationError.FieldReference.IndexOrKeyCase

    OutputConfig.DestinationCase

    ShipmentTypeIncompatibility.IncompatibilityMode

    Modes defining how the appearance of incompatible shipments are restricted on the same route.

    Protobuf enum google.cloud.optimization.v1.ShipmentTypeIncompatibility.IncompatibilityMode

    ShipmentTypeRequirement.RequirementMode

    Modes defining the appearance of dependent shipments on a route.

    Protobuf enum google.cloud.optimization.v1.ShipmentTypeRequirement.RequirementMode

    SkippedShipment.Reason.Code

    Code identifying the reason type. The order here is meaningless. In particular, it gives no indication of whether a given reason will appear before another in the solution, if both apply.

    Protobuf enum google.cloud.optimization.v1.SkippedShipment.Reason.Code

    Vehicle.TravelMode

    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.

    Protobuf enum google.cloud.optimization.v1.Vehicle.TravelMode

    Vehicle.UnloadingPolicy

    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.

    Protobuf enum google.cloud.optimization.v1.Vehicle.UnloadingPolicy

    Waypoint.LocationTypeCase
