    摘要:

    为了应对城市日益增长的物流需求、提高运输效率、并有效缓解现有的物流模式导致的环境污染及道路交通拥堵等问题,提出了基于地铁的城市物流配送模式。将地铁运输与城市道路运输联合起来,研究基于地铁站点的城市物流配送系统的中转节点选址。考虑运输费用、中转费用、固定运营费用、管理费用及投资费用等,构建以总成本最小为目标的城市物流配送系统中转节点选址模型;同时,设计改进的免疫遗传算法,对模型进行求解。最后,以上海市的地铁网络为例,进行仿真实验,得出了较为合理的中转节点选址方案。结果证明了模型与算法的合理性与有效性。

    Abstract:

    In order to respond to the city"s growing logistics demand, improve transportation efficiency, and effectively alleviate the environmental pollution and road traffic congestion caused by the existing logistics model, a subway-based urban logistics distribution model is proposed. The subway transportation and urban road transportation are combined to study the location of the transit node of the urban logistics distribution system based on subway stations. Considering transportation costs, transit costs, fixed operating costs, management costs and investment costs, etc., a model for the location of transit nodes in the urban logistics distribution system with the goal of minimizing the total cost is constructed; at the same time, an improved immune genetic algorithm is designed to solve the model. Finally, taking the subway network of Shanghai as an example, a simulation experiment was carried out, and a more reasonable transfer node location scheme was obtained. The results prove the rationality and effectiveness of the model and algorithm.
