摘要
针对再制造物流网络与传统生产分销物流网络的集成优化设计问题,综合考虑网络中正向和逆向物流的设施集成与运输整合,以及设施建设成本的规模经济效应,基于混合整数非线性规划方法,建立了一种再制造物流网络优化设计的扩展模型,用来确定网络中各种设施的数量、位置及规模,并在由此构成的各条物流路径上合理分配物流量,使运营周期内的净收益最大。最后,通过一个算例对模型进行了数值演算和验证。计算结果表明:该模型能根据物流网络的实际调查数据,得到网络的最优目标函数与决策变量值,能有效辅助再制造物流网络优化设计。
The problem on designing an appropriate integrated logistics network structure for hybrid manufacturing/remanufacturing systems was investigated, the integration of various facilities and combined transportation of forward and reverse logistics in the network was considered, the impact of scale economics on the cost of establishing those facilities was studied, an extended model for the optimal design of remanufacturing logistics network was developed based on mixed integer nonlinear programming approach. According to the model, the numbers, locations and capacities of various facilities and the allocation of corresponding goods flows in the network were ascertained, the objective was to maximize the net revenue in operation period. Finally, the model was tested and verified by a numerical example. Computation result shows that the optimal objective function and decision-making variables of the net can be gained by using the model, and logistics network and the model can be used to assist the decision-making of the network design.
