Hello Michel,

no, there's no priority flag at the vehicles available. And even the sequence of the Fleet's vehicle array is irrelevant as we order the array elements internally to ensure some kind of a determinism.

Once again: what exactly is the usecase or requirement you'd like to fullfill? Sometimes you could start with only your prio A vehicles and if orders remain unscheduled add some prio B vehicles in a second call. Does this approach satisfy your needs?

Best regards,
Bernd

Hello Bernd,

To priorize vehicle, for instance, how can I tell xTour to take one vehicle rather than another depending on its cost ?

Hello Michel,

imagine you have an existing tour structure and you simply want to determine which vehicle of the heterogenous fleet produces the cheapest costs we offer the VehicleScheduling scenario.

Article about Planning scenarios

While the regular optimization (StandardParams, BalancingParams...) is based on reducing abstract distances and driving times the VehicleSchedulingParams are working with the Vehicle costs set in the properties of the fleets vehicles.

The Vehicle Scheduling call requires an input plan and a set of vehicles (usually with different cost settings and properties) and will assign the solution in a way that the chosen vehicles are valid and produce lowest overall costs.
Best regards,
Bernd
