Class RoutingModel.ResourceGroup

com.google.ortools.constraintsolver.RoutingModel.ResourceGroup

Enclosing class:

RoutingModel

public static class RoutingModel.ResourceGroup
extends java.lang.Object

A ResourceGroup defines a set of available Resources with attributes on
one or multiple dimensions.
For every ResourceGroup in the model, each (used) vehicle in the solution
which requires a resource (see NotifyVehicleRequiresResource()) from this
group must be assigned to exactly 1 resource, and each resource can in
turn be assigned to at most 1 vehicle requiring it. This
vehicle-to-resource assignment will apply the corresponding Attributes to
the dimensions affected by the resource group. NOTE: As of 2021/07, each
ResourceGroup can only affect a single RoutingDimension at a time, i.e.
all Resources in a group must apply attributes to the same single
dimension.
