基于GIS和粒子群算法的两级物流配送中心选址优化方法及应用

Optimal Location of Bi-level Logistics and Distribution Centers Based on GIS and PSO

根据总运费最小化原则,以用户空间数据库为背景建立了针对两级配送中心的选址优化模型。为了对选址优化模型求解,提出了一种变异粒子群算法。以地理信息系统(GIS)为平台,对山东省区域物流配送中心的选址优化进行了实证研究,所得结果符合山东省实际情况,表明本文提出的选址优化方法具有较大的应用价值。

According to the minimum freightage principle, the paper establishes an optimal location model for bi-level distribution cen- ters against the background of user space database and proposes a varied PSO method to solve the model. Then on the GIS platform, it carries out an empirical study on the optimal locations of regional logistics and distribution centers in Shandong and yields results that fit the actual situation of the province, proving that the method proposed in this paper is of rather high applied value.
