基于AHP和目标规划的物流配送中心选址模型

Location Model of Distribution Center Besed on Analytic Hierarchy Process and Goal Programming

论述了物流系统配送中心选址所涉及的众多影响因素,这些因素中既有定性因素,又有定量因素。首先用层次分析法对这些影响因素进行处理,得到了各备选点的权值。针对层次分析法无法解决条件约束问题,提出了用层次分析法和目标规划方法相结合用于物流配送中心选址的模型,建立了6个约束方程,1个系统约束方程,以确保只有在配送中心建立的情况下,才能在该配送中心配送物品,而且配送量不能超过它的建设容量。最后通过示例表明该模型能有效地处理物流配送中心选址问题。

Location of distribution center in logistic system involves many factors, some of which are quantitative, and others are qualitative. The weight of each distribution center by using AHP on the basis of analyzing the factors is discussed and selected. For AHP can not solve the problem with constraint, a location model is proposed by use of AHP and goal programming. The model includes six constraint equations and one system constraint equations in order to assure that goods can be distributed in the constructed distribution centers and the amount of distribution can not surpass the center＇s capacity. The model for location of distribution center in logistic system is proved to be effective by examples.
