In this paper we consider a centralized logistics system in which a single company owns the production facility and the set of retailers and establishes warehouses that will replenish the retailers' inventories. We analyze the potential savings that

In this article, we introduce the capacitated warehouse location model with risk pooling (CLMRP), which captures the interdependence between capacity issues and the inventory management at the warehouses. The CLMRP models a logistics system in which

An important aspect of designing a distribution system is determining the locations of the facilities. For systems in which deliveries are made along multiple stop routes, the routing problem and location problem must be considered simultaneously. In

We consider a joint location-inventory problem involving a single supplier and multiple retailers. Associated with each retailer is some variable demand. Due to this variability, some amount of safety stock must be maintained to achieve suitable serv

We introduce a distribution center (DC) location model that incorporates working inventory and safety stock inventory costs at the distribution centers. In addition, the model incorporates transport costs from the suppliers to the DCs that explicitly

We consider several different matching problems that are motivated by applications to selective assembly operations. In the case of maximum cardinality problems, we provide linear time greedy algorithms which we prove optimal via a min-max theorem. W

This paper presents a polynomial-time algorithm for the minimum-weight-cycle problem on graphs that decompose via 3-separations into well-structured graphs. The problem is NP-hard in general. Graphs that decompose via 3-separations into well-structur

A Leontief directed hypergraph is a generalization of a directed graph, where arcs have multiple (or no) tails and at most one head. We define a class of Leontief directed hypergraphs via a forbidden structure called an odd pseudocycle. We show that
