| 摘 要： | 为提高快递配送效率,基于城市快递双层配送网络的构成和优势,建立该网络二级节点选址模型,包括末端配送站点和便民寄存点选址,其中便民寄存点选址需考虑服务半径约束和容量限制。提出分解算法进行模型求解,其中针对便民寄存点选址采用改进的最少点覆盖启发式算法,针对末端配送站点选址采用k-均值聚类算法。利用算例进行模型和算法验证,结果表明,该模型和算法能有效解决城市快递双层配送网络的节点选址优化问题。

| Abstract: | In order to improve the efficiency of express delivery, based on the structure and advantages of the double layer distribution network of urban express delivery, a two level node location model of the network is established, where the nodes include the terminal distribution stations and temporary storage stations, and the service radius constraint and capacity constraint are considered in the location of temporary storage stations. A decomposition algorithm is used to solve the model, where an improved least point coverage heuristic algorithm is applied to the node location of temporary storage stations, and the k means clustering algorithm is applied to the node location of terminal distribution stations. An example is used to verify the model and the algorithm. The result shows that the model and the algorithm can effectively solve the node location optimization problem of the urban express double layer distribution network. |
