基于网络分析方法的物流配送中心选址的研究

A Study on the Location Selection of Logistics Distribution Center based on the Network Analysis

经济全球化,信息技术和电子商务的发展对物流产生了深刻的影响,使之呈现出新的特点。这些特点对配送中心选址的研究提出了更高,更新的要求。本文在对GIS网络分析方法的阐述和P中心选址模型的分析的基础上,建立了配送中心选址优化模型。该模型通过引入商品保管费用、处理费用、配送中心建造费用对P中心选址模型进行了拓展,并通过总费用最小化确定配送中心的数量、位置以及资源点与配送中心、配送中心与用户之间的供需关系。

Economic globalization, the development of information technology and electronic commerce have a profound impact on logistics, and give rise to the emergence of new characteristics of logistics. These characteristics, in turn, pose a higher and newer demand on the study of location selection of distribution center. In this paper, the optimized location model is built on the base of the illustration about GIS network analysis and the analysis of P-median location model. Through bringing in the costs of maintaining commodity, handling commodity and building distribution center ,this model can expand the P-median location model. Meanwhile, by means of minimizing total cost, it can also determine the quantity and location of distribution center, as well as relationship between supplying spots and distribution center, and relationship between users and distribution center.
