We developed an efficient heuristic to solve a joint location-distribution-inventory model for a three layered supply chain. A firm must locate distribution centers to supply a commodity to spatially distributed retailers with stochastic demand. The solution approach is based on Lagrangian...

In this paper, we propose a simultaneous approach to incorporate inventory control decisions--such as economic order quantity and safety stock decisions--into typical facility location models, which are used to solve the distribution network design problem. A simultaneous model is developed...

This paper addresses the problem of designing a household waste collection system for rural insular areas using a barge for transportation, based on a novel mixed integer programming model that simultaneously integrates decisions of waste collection sites selection within the islands to be...

This article presents a model to assist decision makers in the logistics of a flood emergency. The model attempts to optimize inventory levels for emergency supplies as well as vehicles’ availability, in order to deliver enough supplies to satisfy demands with a given probability. A...
