集合覆盖模型在京东快递配送中心选址问题中的研究

Research on the Collection Coverage Model in the Location Problem of Jingdong Express Distribution Center

集合覆盖模型在设施选址决策中有着重要的地位和实际应用价值。针对区域快递配送中心的选址问题,本文以京东快递在佛山市快递配送中心选址为例,通过层次分析法定性定量分析配送中心选址的影响因素,确定主要指标评价体系,在最低费用成本和覆盖所有需求点的约束条件下,建立集合覆盖模型并运用贪婪算法进行求解,确定京东快递配送中心在佛山区域的理想布设。通过对佛山市京东快递配送中心选址研究,本文证实了在考虑建立数量最少快递配送中心的前提下货物能够按时送达需求方,同时充分利用模型的有效性和优越性,实现总成本最小化的目标,对于京东快递配送中心的选址方法具有普适性与推广性。

The aggregate coverage model has an important position and practical application value in facility location decision. In view of the location problem of regional logistics distribution center, this paper takes the location selection of JD Express in Foshan Express Center as an example to analyze the factors affecting the location of the distribution center through the analytic hierarchy analysis, and determine the main indicator evaluation system at the lowest cost and meet all the requirements. Under the constraint of demand point, the aggregate coverage model is established and the greedy algorithm is used to solve the problem, and the ideal layout of JD Express Distribution Center in Foshan area is determined. Through the research on the site selection of Foshan JD Express Distribution Center, this paper confirms that the goods can be delivered to the demand side on time under the premise of considering the establishment of the minimum number of logistics distribution centers, while making full use of the effectiveness and superiority of the model to achieve the goal of minimizing the total cost. For the location selection method of JD Express Distribution Center, it has universality and promotion.
