I’m trying to optimize the best routes VRP with OR-Tools. I couldn’t find the right function in the documentation.
CASE: Some customers only accept pickup trucks, some accept only trucks, some accept both trucks, pickup, and vans. There’s a single depot location and vehicles should carry orders to the right customers with accepted vehicles.
Those vehicles I have
Customers accept those vehicle types
These vehicles should be directed to the appropriate customers.
Do you have any thoughts or are there any or-tools function regarding this?
You can use the
Pseudo code in Python (using customer_id as node_id)
# Vehicles list trucks = [1, 3, 6, 7, 9, 10] vans = [4, 5] pickups = [2, 8] # location list with a tuple (location, truck, van pickup) locations = [ (1, True, True, True), # C-01 (2, True, True, False), # C-02 (3, True, False, False), # C-03 (4, True, True, True), # C-04 ... ] for location, truck_allowed, van_allowed, pickup_allowed in locations: index = manager.NodeToIndex(location) allowed_vehicles =  # you can add -1 iff the location can be dropped if truck_allowed: allowed_vehicles.extend(trucks) if van_allowed: allowed_vehicles.extend(vans) if pickup_allowed: allowed_vehicles.extend(pickups) routing.VehicleVar(index).SetValues(allowed_vehicles)
side note: solver vehicle ID start at 0 but here I followed you vehicle_id convention starting at 1…
