废弃物回收的多层逆向物流网络优化设计问题研究

废弃物逆向物流网络设计问题是一个关系到经济效益和社会效益的问题.本文研究了废弃物逆向物流网络设计问题,包括选择中转站和处理站的地址,确定将产生点的废弃物分配给中转站以及从中转站运送到处理站的最佳策略,确定处理站的容量.考虑了在满足公众的意愿的情况下,建立了一个多目标的纯整数规划模型,最小化总的建设费用和设施对公众产生的负效用.设计了基于启发式的两阶段分解算法求解,从而构建一个废弃物回收的多层逆向物流网络.最后的算例仿真表明了算法的有效性和可行性.

Optimal Design of the Multi-Echelon Reverse Logistics Network for Solid Wastes

The design of reverse logistics network for solid waste is concerned with economy and society.This paper addresses the design of reverse logistics network for solid wastes that involves locating transfer facility and dispose facility,and determining the best strategy for allocating the wastes sources to transfer plants and transporting the wastes from transfer facilities to dispose facilities.The goal is to select the optimum numbers,locations and capacities of transfer facilities and dispose facilities to open so that all wastes sources are satisfied at minimum total costs of the reverse logistics network and at minimum disutility to people.We develop a multi-bjective integer programming model and provide an efficient heuristic solution procedure for the reverse logistics network design.Computational tests demonstrate the efficiency and feasibility of our heuristics.
