【摘要】：本文研究了O2O转型背景下大型零售企业城市配送网络优化面临的中转中心选址及末端需求点分配问题,构建了考虑配送中心到末端需求点近似配送距离的中转中心选址及末端需求点分配联合优化模型,设计了集成遗传算法和禁忌搜索算法的混合算法求解模型,通过混合算法与CPLEX的对比证明了本文算法的有效性。以苏宁重庆主城核心区域的城市配送网络优化为实例进行测算,给出了苏宁重庆主城核心区域中转中心的选址及需求点分配的联合优化方案。联合优化方案表明城市物流"最后一公里"末端配送成本占城市物流总成本的比例超过60%;车型是影响城市物流总成本的关键因素,选择与中转中心容量接近的车型能够显著降低城市物流总成本,减少运输距离;合理的中转中心选择能提高短距离配送比例和减少配送总距离。
[Abstract]:In this paper, we study the location of transit center and the distribution of terminal demand points in the context of O2O transformation for large retail enterprises in urban distribution network optimization. A joint optimization model of transit center location and terminal demand point allocation considering the approximate distribution distance from distribution center to terminal demand point is constructed, and a hybrid algorithm model integrating genetic algorithm and Tabu search algorithm is designed. The comparison between the hybrid algorithm and CPLEX proves the effectiveness of this algorithm. Take the urban distribution network optimization of the core area of SUNING Chongqing as an example to calculate. This paper gives the joint optimization scheme of location and demand point allocation of the transit center in the core area of SUNING Chongqing main city. The joint optimization scheme shows that the city logistics is "the last kilometer". The proportion of terminal distribution cost to the total cost of urban logistics is more than 60. The type of vehicle is the key factor to affect the total cost of urban logistics. The choice of the model which is close to the capacity of transit center can significantly reduce the total cost of urban logistics and reduce the transportation distance. Reasonable transit center selection can increase the proportion of short distance distribution and reduce the total distance of distribution.

【正文快照】： 1引言布局O2O模式是国内大型零售企业应对电商对冲击的重要途径。2014年国内连锁百强有75家开展网络零售,其中23%的门店提供自提服务。门店是实施O2O的关键环节,目前国内大型零售企业的O2O转型模式分为三种。第一种是门店仅提供商品展示及消费体验服务,不涉及任何线上订单的物
