We analyze the characteristics of the logistics systems including both direct and reverse flows, their activities and structure. We address the strategic planning problem of such systems and propose a facility location model as an extension of the simple plant location problem while taking into account the specific constraints related to reverse flows of directly reusable items. For solving this model,...
This article develops simple and easy-to-use approximation formulae for the length of a Chinese Postman Problem (CPP) optimal tour on directed and undirected strongly connected planar graphs as a function of the number of nodes and the number of arcs for graphs whose nodes are randomly distributed on a unit square area. These approximations, obtained from a multi-linear regression analysis, allow...
After a brief introduction to the basic concepts of reverse logistics, we present a two-level location problem with three types of facility to be located in a specific reverse logistics system, named a Remanufacturing Network (RMN). For this problem, we propose a 0–1 mixed integer programming model, in which we simultaneously consider “forward” and “reverse” flows and their mutual interactions. An...
