This paper presents a solution method based on column generation for the Inventory Location Routing Problem. It chooses simultaneously the location of a set of depots to decide upon the inventory management and the set of routes to satisfy customers’ demands, in order to minimize the total system cost. The original problem is decomposed into a Master Problem (Location Problem) and an Auxiliary ...

one of methods of improvement of the material flow is cross docking that in is considered as a good method to reduce inventory and improve customer satisfaction. too, the vehicle routing problem is one of the important problems in distribution management and its goal is to find paths for delivering various cargos. therefore, this study was conducted in order to vehicle routing problem with cros...

This paper considers the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Our routing scheme is a combination of two protocols called Terminode Local Routing (TLR) and Terminode Remote Routing (TRR). TRR is activated when the destination is remote and uses location of the destination obtained either via location management or by location tracking. TLR acts when ...

Transportation in economic systems such as services, production and distribution enjoys a special and important position and provides a significant portion of the country's gross domestic product. Improvements in transportation system mean improvements in the traveling routes and the elimination of unnecessary distances in any system. The Vehicle Routing Problem (VRP) is one of the practical co...

We present an information theoretic analysis of the minimum routing overhead incurred for reliable routing of packets using location-based routing. We formulate the minimum routing overhead problem as a rate-distortion problem and derive a lower bound on the minimum routing overhead incurred. We also characterize the deficit in transport capacity caused by the routing overheads. It is observed ...

A smooth operation of the fourth party logistics supply chain network requires cooperation multiple distribution centers and third logistics. Any unexpected disruption caused by a certain center may lead to serious consequences whole chain. Therefore, we study reliable location-routing problem in design considering risk centers. In addition, minimize total cost proposed problem, scenario-based ...
