Theoretical and empirical studies on designing and reconfigurating the supply chain network

本文主要包括三个部分：1.建立了供应链网络的设计与重构的混合整数规划模型。分支定界法是解决这些问题的著名方法。然而，它是困难的大整数规划模型。提出了拉格朗日松弛法和遗传算法。通过数值算例，讨论了三种方法。2.提出了一种新的基于加权偏好流的多目标优先分析方法。在这种情况下，排名靠前的分析被广泛使用。应用一种新的方法，对一家大型家用电器公司分布在全国各地的仓库进行了各种重组方案的评估，特别是对日本东北地区仓库合并的可能性进行了评估。3供应链管理中的一个主要问题是供应链中各成员之间的协调。考虑一个简单的报童问题，利用效用理论研究了零售商的风险态度对协调的影响。

This report consists of three parts1 The design and reconfiguration of the supply chain network are formulated as mixed integer programming models. The branch and bound method is well known for solving them. It is, however, it is difficult for large integer programming models. Lagrangian relaxation method and genetic algorithm are also proposed. By numerical examples, we discussed three methods.2 We proposed a new exploitation procedure based on weighted preference flows in multicriteria outranking analysis.Imprecise data and qualitative multicriteria are inherent in evaluating complex strategic alternatives of reconfiguration. In that case, outranking analysis has been widely used. Applying a new procedure, we conducted a case study of the evaluation of various reconfiguration alternatives of the warehouses distributed all over the nation of a major household appliances company, especially, focusing on the possibility of merging the warehouse in North East region in Japan.3 One of the major concerns in supply chain management is the coordination among various members in a supply chain.Considering a simple newsvendor problem, we investigated the effect of the retailer's attitudes toward risk on the coordination with the aid of utility theory.
