基于AHP及混合整数规划法的配送中心选址

Location of Distribution Center According to Methods of AHP and Mixed-integer Programming

本文针对配送中心选址的因素进行分析，采用AHP法以及混合整数规划法对配送中心选址进行定性与定量结合的方法进行建模分析。首先由AHP法分析各因素得出最重要的三个因素：运输费用、物流服务需求量、交通条件；然后依照配送中心选址所产生费用最小化的原则来建立采用0～1整数变量的混合整数规划模型。此模型考虑了配送中心固定成本的分摊问题、0—1整数变量及五年规划期的最优，保证选址模型的可行性。提出一个较有效的配送中心选址的方法。

This article is analysed the factor that location of distribution center, adopted AHP and the mixture integral programming to be established a model model by analysis method of assurancing property and fixed amount. Firstly it＇s analyzed by AHP of the most important three factors： transport expenses, logistics service demand and transportation condition; then on decreasing and minimuming expenses from from location of distribution center, it＇s build up the mixed - Integer Programming model by 0 - 1 integral changes. This article is considered to sharied problem about ixed expenses of distribution center, 0 - 1 integrals change in this model and superior in programming period of five year, put forward a more effective method about location of distribution center.
