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 ...

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 ...

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 ...

Waste clean-up after a disaster is one of the most critical tasks in response stage management. We develop model to minimise cost and duration waste considering using Temporary Disaster Management Sites (TDWMSs), which can store process before it sent final disposal sites. The problem that arises be seen as Multi-Period Two-echelon Location Routing Problem (MP-2ELRP) main decisions are location...
