I am building a multi depot multi vehicle transportation model. The model is running but gives 0 as optimal.
I am just about to introduce the vehicles set and this is where i am having trouble now.
I want each depot to have two type of vehicles. This is the best way I can get to right now.
I want a set of vehicle type and a set of depot. I want to tell the model that each depot in this example:
depot 1 has 2 scooters, and 1 truck, and depot 2 has 3 scooters and 1 truck.
Is there a better way to do this, and how to resolve the error.
Attached is my model.
