基于现值法的制造/再制造集成物流网络设计

为了合理构建制造／再制造集成物流网络，采用现值法，考虑计划期内运营成本的时间价值，基于混合整数线性规划方法，建立了一种制造／再制造集成物流网络优化设计模型．据此确定网络中分销中心和回收中心的数量和位置，并在由此构成的各条物流路径上合理分配物流量，以使投资成本和计划期内运营成本的现值之和最小．最后，通过算例验证了该模型的有效性，并对模型参数进行了灵敏度分析．

Integrated Logistics Network Design for Hybrid Manufacturing/ Remanufacturing Systems Based on Present Worth Method

To set up an appropriate integrated logistics network for hybrid manufacturing/ remanufacturing systems, an optimization model for designing such a network was established based on mixed integer linear programming approach. In this model, the present worth method was used to consider the time value of operational costs over a planning horizon. According to the model, the numbers and locations of distribution centers and collection centers, and the allocation of the corresponding goods flows in the network can be decided upon to minimize the sum of the investment costs and the present equivalent of the future operational costs over the planning horizon. Finally, the validity of the modal was demonstrated by a numerical example and a sensitivity analysis of the model was performed.
