基于随机需求的两级多期供应链网络规划模型

本文以三级供应链网络为例,研究了具有随机因素的,两级多期决策的供应链网络优化问题.优化的具体内容包括两个方面:供应链节点的选址和相应配送系统的设计.文章首先在现有研究成果的基础上,将模型设计拓展到多期决策领域.接下来,针对因素的随机性问题,应用了蒙特卡罗方法对随机因素进行了模拟和采样.最后,模型的目标函数不仅考虑了最小成本,同时还考虑了顾客满意度.对多目标模型的处理采用了e条件限制法.用这种方法的得到的供应链网络优化结果是一系列帕累托最优解,它使得决策者可以按照自己的偏好做出最后选择.

Two-layer Multi-period Supply Chain Design Under Uncertainty

This paper proposed a two location layers multi-period supply chain model under uncertainty.The design and retrofit problem consist of two aspects:the locations of the SC nodes,such as plants,warehouses,and the associated distribution systems.First,based on former presented models,this paper extends the study to the multi-period area.Then,in order to take into account the effects of the uncertainty in the production scenario,a Mont Carlo method is used.The problem objective is assessed by considering not on...
