基于城市共同配送网络体的配送中心选址研究

Location of Distribution Center Based on the System Structure of Urban Joint Distribution

随着现代社会经济的迅猛发展,城市规模日益扩大,对物流活动的要求越来越高。由于多品种、少批量、多频率的货物配送增加了城市交通的负荷,共同配送变得异常重要。针对B2C和C2C类货物的城市共同配送,本文建立了城市共同配送网络体系,基于此,解决了二级配送中心的选址问题,同时,本文根据中心地理论和六边形法则确定了城市配送中心数量;根据K-means聚类的方法,确定了城市配送中心的位置;最后,根据Voronoi图理论,确定了城市配送中心的服务范围。并以上海市内环区域为研究案例,验证了本文提出的方法的可行性。

With the rapid development of modem economy, people have already put forward higher requirements for the urban distribution, which requires many varieties, little batch and multi-frequency distribution, and this increases the load of traffic in the city as well. In this circumstance, joint distribution becomes more and more important. For the urban joint distribution of B2C and C2C goods, system structure of urban joint distribution was established, meanwhile, this paper applied the central place theory to identify the number of distribution center, used the K-means clustering analysis algorithm to determine the distribution center location and selected Voronoi diagram to divide the service area of distribution center, so as to address the key issues during the construction of joint distribution. Finally, Shanghai inner ring area was set as an example to verify the feasibility of the proposed approach.
