摘　　要：逆向物流网络设计是企业获得经济利益和提高竞争力的战略决策之一。本文针对售后服务逆向物流网络设计问题,考虑了同时优化物流网络运营成本和服务水平,提出了一个多目标整数规划模型来确定服务中心的个数、位置、容量等级以及客户区指派到服务中心的策略,并得到成本和服务之间的权衡关系。设计了一种混合多目标进化算法求解模型。通过实例分析,找出了影响物流网络设计的关键因素。通过算例测试,对混合多目标进化算法和ε约束法进行了比较,结果表明混合多目标进化算法对求解中大规模的问题是一种良好的方法。Reverse logistics network design is a strategic decision for company. This paper addresses the analysis of reverse logistic networks for post-sale service. A multi-objective integer programming which optimizes the cost and service level simultaneously is developed to determine the numbers and locations and capacity levels of service centers and the assignment of customer areas to service centers. A hybrid multiobjective evolutionary algorithm is proposed to solve the model. Through analysis of the example, some conclusions about the network design are obtained. Finally, we compared the hybrid multi-objective evolutionary algorithm with the e -constraints, The results show our algorithm is very efficient for median-larger scale problem.
