摘要

本文研究基于城市地铁网络的快递路线选择和配送成本问题，简称地铁快递(MeD)。考虑到快递运输的特点和城市地铁网络的复杂性，提出了三种不同时段的配送模式，并建立了以配送总成本最小为目标的严格集成整数线性规划模型。为了有效求解最优问题，改进并设计了一种标准遗传算法。最后，以宁波地铁网络为例，验证了模型和算法的实用性和有效性。结果表明:当快件配送数量为1980件时，三种不同的MeD模式可分别降低40.5%、62.0%和59.0%的运输成本;案例分析的结果将有助于指导快递公司与城市地铁网络合作，并根据所需的快递数量选择相应的配送方式。

Route Selection and Distribution Cost of Express Delivery: An Urban Metro Network Based Study

Route selection and distribution costs of express delivery based on the urban metro network, referred to as metro express delivery (MeD), is addressed in this study. Considering the characteristics of express delivery transportation and the complexity of the urban metro network, three distribution modes of different time periods are proposed and a strict integrated integer linear programming model is developed to minimize total distribution costs. To effectively solve the optimal problem, a standard genetic algorithm was improved and designed. Finally, the Ningbo subway network is used as an example to confirm the practicability and effectiveness of the model and algorithm. The results show that when the distribution number of express delivery packages is 1980, the three different MeD modes can reduce transportation costs by 40.5%, 62.0%, and 59.0%, respectively. The results of the case analysis will help guide express companies to collaborate with the urban metro network and choose the corresponding delivery mode according to the number of express deliveries required.
