9 Abstract In rapidly growing urban areas, it is deemed vital to expand (or contract) 10 an existing network of public facilities to meet anticipated changes in the level of 11 demand. We present a multi-period capacitated median model for school network 12 facility location planning that minimizes transportation costs, while functional costs 13 are subject to a budget constraint. The proposed ...

different decisions, including location decisions of companies which are operating in international dynamic environment are subject to significant uncertainty.so in this research an international facility location problem under uncertainty is considered and an integrated model for strategic and operational planning is presented. in strategic level countries are assessed according to internation...

location-allocation is a combinatorial optimization problem, and is defined as non deterministic polynomial hard (np) hard optimization. therefore, solution of such a problem should be shifted from exact to heuristic or meta heuristic due to the complexity of the problem. locating medical centers and allocating injuries of an earthquake to them has high importance in earthquake disaster managem...

Solving the Inventory Location-Routing Problem can been seen as an approach to optimize both a supply chain design and its operations costs. Assumptions consider that vehicles might visit more than one retailer per route and that inventory management decisions are included for a multi-depot, multi-retailer system with storage capacity over a discrete time planning horizon. The problem is to det...

This paper studies a location–routing–inventory problem in a multi-period closed-loop supply chain with multiple suppliers, producers, distribution centers, customers, collection centers, recovery, and recycling centers. In this supply chain, centers are multiple levels, a price increase factor is considered for operational costs at centers, inventory and shortage (including lost sales and back...
