One of my Depots MUST BE the last one.

Hello,

i'm searching a solution for the following problem:

I have two depots (Depot A and Depot B) and a couple of orders.
The tour starts at Depot A. After servicing the orders, the truck should visit Depot B where the goods should be unloaded.
After all, the tour should finally end in Depot A.

The question is...

Where is the setting to assign Depot B as the last stop in the tour, before returning to Depot A.

Thank you very much for your answers.

Have you tried including Depot B in the Orders feature with the AssignmentRule set to (1) Preserve route and relative sequence? This will allow you to always make Depot B the last stop before returning to Depot A.

Hi,

When you know the sequence numbers for all orders, you can use "AssignmentRule set to (1) Preserve route and relative sequence" to lock Depot B as the second last visit in the route. However, if you don't know the sequence numbers, VRP solver cannot solve your problem directly. There is a workaround for it.

You can use Depot B as the end depot for the route. This solution will not include the part traveling from Depot B to the end Depot A. If you want to include this part in the solution, after solving the VRP layer, you may load Orders and Depot Visits into a route layer as Stops in the sequence created in VRP layer, and add a copy of Depot A as the last stop in the route layer. Solving this one will return you the complete route.

Thanks.
