基于GIS和遗传算法的物流配送中心选址研究

Study on Location Selection of Logistics Distribution Center Based on GIS and Genetic Algorithm

物流配送中心的选址是物流系统优化的一个具有战略意义的问题。在分析传统物流配送中心选址算法不足的基础上,建立了一个基于GIS和遗传算法的物流配送中心选址模型。首先确定配送中心选址的目标及影响选址的因素,接着利用GIS的空间分析技术,定量分析可在电子地图上表现的物流配送中心选址的影响因素,得出一系列候选地点,最后利用遗传算法,求解得出最佳选址地点,并通过实例研究表明该算法的可行性。

The location selection of logistics distribution center is of strategic significance to logistics system optimizing.Based on analysis of traditional location selection algorithms of logistics distribution center,an algorithm based on GIS and genetic algorithm is established.First,the location selection and its influence factors are determined;then influence factors of location selection are analyzed by means of GIS spatial analysis techniques,a serial of candidate sites are obtained;at last the best location was obtained based on genetic algorithm,and the case study shows that the algorithm is feasible.
