The location-routing problem is one of the most important location problems for designing integrated logistics systems. In the last three decades, various types of objective function and constraints have been considered for this problem. However, time window constraints have received little attention, despite their numerous real-life applications. In this article, a new 4-index mathematical mod...

To solve the location-routing problem of maritime emergency materials distribution (MEMD-LRP) multi-agent joint decision, a bi-level programming model MEMD-LRP is constructed. The established on premise considering rescue time window and priority, aiming at strong regional characteristics accidents, timeliness rescue, great difficulty high cost so on. From point view management department, uppe...

The cash deployment strategy for a network of ATMs should take into account the analysis of inventory policies, logistics costs as well as the routing of replenishment vehicles. The optimal strategy has to focus on the reduction of cash-related expenses while safeguarding that ATMs do not run out of cash. Shorter routes with high time window constraints violations are not always the best soluti...

In the vehicle routing problem with time window (VRPTW), the objective is to minimize the number of vehicles and then minimize the total time travelled. Each route starts at the depot and ends at a customer, visiting a number of customers, each once, en route, without returning to the depot. The demand of each customer must be completely fulfilled by a single vehicle. The total demand serviced ...
