Abstract

In today’s intensive competition conditions, it is an inevitable necessity for the companies operating in the e-commerce sector to manage their physical distribution processes efficiently and effectively. The most important step in e-commerce logistics processes is the last step delivery operations in the city. In order for these operations to be carried out quickly and efficiently, delivery vehicles and personnel must be optimally led. These problems, referred to as vehicle routing problem (VRP) in the literature, include determining the least cost routes that vehicles will cover to meet customer needs. In this study, the urban delivery problems of the enterprises operating in the online retail sector are examined. In line with these problems, VRP for urban e-commerce deliveries has been modified; open, multi-depot, distribution aggregation, time-window VRP is discussed. A mathematical model for the modified VRP has been developed and a new heuristic algorithm consisting of two stages has been developed for large-scale problems. The developed algorithm was tested on three different cases. The results are compared with the solution of the nearest neighbor method and the performance of the proposed algorithm is presented.
城市电子商务配送的两阶段启发式算法建议
在当今激烈的竞争条件下,对电子商务领域的公司进行高效有效的物流管理是必然的需要。电子商务物流过程中最重要的一步是在城市的最后一步交付操作。为了使这些行动迅速有效地进行,必须对运送车辆和人员进行最佳的领导。这些问题在文献中被称为车辆路线问题(VRP),包括确定车辆将覆盖的最低成本路线以满足客户需求。本研究考察了网络零售企业的城市配送问题。针对这些问题,对城市电商配送VRP进行了修改;讨论了开放式、多仓库、分布聚合、时间窗VRP。建立了改进VRP的数学模型,并提出了一种针对大规模问题的两阶段启发式算法。开发的算法在三种不同的情况下进行了测试。将结果与最近邻法的解进行了比较,并给出了该算法的性能。
