基于物流系统接口模型的多式联运运输优化研究

Research on Multimodal Transport Combination Optimization Based on Logistics System Interface Model

多式联运运输过程中多种运输方式的无缝衔接仍存在很多问题,阻碍多种运输方式的优化组合。现从物流系统接口的角度,首次提出多式联运中物流系统接口模型(Logistics System Interface Model),探讨了物流系统接口在多式联运运输中的作用,结合接口处的成本和运输过程的成本,构建多式联运总运输费用和总运输时间最小的双目标优化问题,通过双目标整数规划模型得到运输方式和路线的最优组合。结果表明通过物流系统接口模型可以进一步改善多种运输方式的衔接,有利于优化多式联运的运输组合。

In the multimodal transport process,there are still many problems of the perfect connection of multimodal transport,which would hinder the optimal combination of multimodal transport.From the perspective of the logistics system interface,this paper proposes the logistics system interface model in multimodal transport for the first time,discusses the functions of logistics system interface in multimodal transport,establishes a bi-level programming problem of the combination of the lowest cost and minimized total transport time,and obtains the optimal combination of modes of transport and transit routes through the double objective integer programming model.The result demonstrates that through the logistics system interface model,the connection of multimodal transport can be further optimized which can optimize the combination of multimodal transport.
