中文摘要：

在需求充满不确定性,成本结构复杂的现实情况下,已知工厂和顾客的地理位置,如何从初步拟定的候选点中选择配送中心的建设位置,同时规划配送中心与顾客的配送关系,是公司决策中经常碰到的一个问题。为解决这一问题,建立了在模糊需求环境下,整体考虑与选址相关的各项成本,如库存、运输、仓库固定成本与内部搬运成本等的三级物流网络选址模型,并进而利用模糊数学领域的可信性理论,对模型进行了优化整理,得到了同解模型。指出了同解模型是整数规划问题的解法。

英文摘要：

How to select the location of distribution centers from the candidates, and decide the distribution relationship, especially when the demand is uncertain and the cost structure is complex is given the location of the plant and customers. It is a common network location problem for the companies. To solving the problem, a model is established through credibility theory, under fuzzy demand environment, with the aim of minimizing the total cost of inventory, transportation, fixed cost ＆ material handling cost in a 3-level logistics network. After simplification ,which is find that the model is an integer programming problem, and gives the method.
