Google Cloud Optimization V1 Client - Class ShipmentRoute (0.3.4)

Reference documentation and code samples for the Google Cloud Optimization V1 Client class 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 | | | | || || | | | | | | || --++-----------------------------------------------------------------++-->

Parameters
Name	Description
`data`	`array` Optional. Data for populating the Message object.
`↳ vehicle_index`	`int` Vehicle performing the route, identified by its index in the source `ShipmentModel`.
`↳ vehicle_label`	`string` Label of the vehicle performing this route, equal to `ShipmentModel.vehicles(vehicle_index).label`, if specified.
`↳ vehicle_start_time`	`Google\Protobuf\Timestamp` Time at which the vehicle starts its route.
`↳ vehicle_end_time`	`Google\Protobuf\Timestamp` Time at which the vehicle finishes its route.
`↳ visits`	`array<Google\Cloud\Optimization\V1\ShipmentRoute\Visit>` Ordered sequence of visits representing a route. visits[i] is the i-th visit in the route. If this field is empty, the vehicle is considered as unused.
`↳ transitions`	`array<Google\Cloud\Optimization\V1\ShipmentRoute\Transition>` Ordered list of transitions for the route.
`↳ has_traffic_infeasibilities`	`bool` When OptimizeToursRequest.consider_road_traffic, is set to true, this field indicates that inconsistencies in route timings are predicted using traffic-based travel duration estimates. There may be insufficient time to complete traffic-adjusted travel, delays, and breaks between visits, before the first visit, or after the last visit, while still satisfying the visit and vehicle time windows. For example, `start_time(previous_visit) + duration(previous_visit) + travel_duration(previous_visit, next_visit) > start_time(next_visit)` Arrival at next_visit will likely happen later than its current time window due the increased estimate of travel time `travel_duration(previous_visit, next_visit)` due to traffic. Also, a break may be forced to overlap with a visit due to an increase in travel time estimates and visit or break time window restrictions.
`↳ route_polyline`	`Google\Cloud\Optimization\V1\ShipmentRoute\EncodedPolyline` The encoded polyline representation of the route. This field is only populated if OptimizeToursRequest.populate_polylines is set to true.
`↳ breaks`	`array<Google\Cloud\Optimization\V1\ShipmentRoute\PBBreak>` Breaks scheduled for the vehicle performing this route. The `breaks` sequence represents time intervals, each starting at the corresponding `start_time` and lasting `duration` seconds.
`↳ metrics`	`Google\Cloud\Optimization\V1\AggregatedMetrics` Duration, distance and load metrics for this route. The fields of AggregatedMetrics are summed over all ShipmentRoute.transitions or ShipmentRoute.visits, depending on the context.
`↳ route_costs`	`array\|Google\Protobuf\Internal\MapField` Cost of the route, 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 route. In other words, costs["model.shipments.pickups.cost"] is the sum of all pickup costs over the route. 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.
`↳ route_total_cost`	`float` Total cost of the route. The sum of all costs in the cost map.
`↳ end_loads`	`array<Google\Cloud\Optimization\V1\CapacityQuantity>` Deprecated: Use Transition.vehicle_loads instead. Vehicle loads upon arrival at its end location, for each type specified in Vehicle.capacities, `start_load_intervals`, `end_load_intervals` or demands. Exception: we omit loads for quantity types unconstrained by intervals and that don't have any non-zero demand on the route.
`↳ travel_steps`	`array<Google\Cloud\Optimization\V1\ShipmentRoute\TravelStep>` Deprecated: Use ShipmentRoute.transitions instead. Ordered list of travel steps for the route.
`↳ vehicle_detour`	`Google\Protobuf\Duration` Deprecated: No longer used. This field will only be populated at the ShipmentRoute.Visit level. This field is the extra detour time due to the shipments visited on the route. It is equal to `vehicle_end_time` - `vehicle_start_time` - travel duration from the vehicle's start_location to its `end_location`.
`↳ delay_before_vehicle_end`	`Google\Cloud\Optimization\V1\ShipmentRoute\Delay` Deprecated: Delay occurring before the vehicle end. See TransitionAttributes.delay.

getHasTrafficInfeasibilities

When OptimizeToursRequest.consider_road_traffic, is set to true, this field indicates that inconsistencies in route timings are predicted using traffic-based travel duration estimates.
