Multi Depot VRP with Intermediate Facilities
Hi @Marcel Hunting , thanks for your response The model works well when using small instance, but the infeasible rise up when using large instance. I’m guessing that the vehicle’s capacity aren’t sufficient to fulfill each demand, could you assist me how to make the vehicle can be multiple visit for each node or the demand can be fulfilled by different vehicles..?
Hi @mohansx Thanks for your reply, actually I’m trying to develop Multi-depot Green VRP with inter facilities. So the main idea is products could be transfered directly from “Kilang” (depot) to “Depot” (customer), and also to “Terminal” (Inter Facilities) to buffer some products. Since it is multiobjective, least cost and emission, I create Fuel consumption variable to calculate either least cost and emission based on distance matrix, but the model that I already attached still focusing least cost problem. Here i attached paper about ACO Algorithm
