多周期多目标再制造物流网络设施动态选址研究

Multi-Period and Multi-Objective Dynamic Location Model for Remanufacturing Logistics Network

考虑市场主体对再制造品需求量的不确定性及库存对选址策略的影响,以构建物流网络总成本最小和对居民负效用最小为目标,建立多周期多目标再制造物流网络的动态选址模型。通过该模型,可以确定各周期内网络设施的位置分布、数量及设施间的运输量等。通过比较静态选址和动态选址结果,可证明动态选址能够充分利用网络设施资源,兼顾各周期不同情况,具有很强的应用性。

In this paper, considering the uncertainty of consumers＇ demand and inventory, we build a multi-period and multi-objective site location model with the goal of minimizing the total cost and the disutility for residents. By solving this model, the location, the number of each kind of facili- ties and the logistics flow allocation among facilities are determined. Finally, the results are compared with a static site location model to highlight the advantages of the dynamic site location model and it has strong applied value.
