一种基于重心法的连锁经营企业区域物流配送中心选址模型

Location Models for Regional Logistics Distribution Centers of Chain Store Enterprises Based on Gravity

提出了配送中心吸引力指数的概念,建立了以吸引力指数最大为目标函数的选址理论模型。考虑了模型解决具体问题的实用性,引入交通区位和地价2个权重因素对不同候选地址的吸引力指数进行加权,实现连锁经营企业区域物流配送中心的选址优化。通过具体算例表明算法能够获得更切合实际的目标解,且搜索时间短、效率较高。

This paper presents a new concept of distribution center＇ s attraction index, and establishes a location model with the objective function of the attraction index. Two multiplier coefficients of traffic factors and price of grounds are introduced to improve the practicability of the model. Enterprises can optimize their regional logistics distribution center＇ s locations via the two multiplier coefficients, and the model can be used to find better results consuming less time and with higher efficiency, which is tested by an example.
