This paper deals with the question of optimal inventory sizes in a compétitive environment in which the demand for a product at a vendor dépends on the inventory level of the product at that vendor relative to the inventories of the same product held by other competing vendors. The total demand for the product at all vendors is assumed to be fixed. This question is examined for two different re...

Product returns are often characterized by a dual uncertainty on time and quantity. In the literature on inventory management with product returns, best forecasts have been associated with methods that use the most information regarding product return history. In practice however, data is often scarce and unreliable. In this paper we investigate the impact of (mis)information on inventory perfo...

Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, they can interchange workforce and products inventory; thus, thei...

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 ...

For nearly a decade, I have argued that the Federal Reserve should maintain a target path of total demand in the American economy. The best measure of total demand, I suggest, is what the Department of Commerce calls “final sales to domestic purchasers.” This aggregate is equal to nominal gross domestic product minus the change in private inventories minus exports plus imports. In recent years,...

This paper focuses on optimizing the long- and short-term planning of perishable product supply chain network (PPSCN). It addresses integration strategic location, tactical inventory, operational routing decisions. Additionally, it takes into consideration specific characteristics products, including their shelf life, inventory management, transportation damages. The main objective is to minimi...

Distribution network design is one of the important issues in supply chain management. Two important sub-problems of distribution network design are inventory and location decisions. Traditional approaches considered inventory and location decisions separately which might result in suboptimal solutions. This paper considers the design of a distribution network and simultaneously determines the ...
