    摘要:

    在高附加值、高时效性要求的货物日益激增的需求驱动下,航空货运和高铁货运联运常态化趋势逐渐显现。在运输方式转换中,衔接环节一定程度上影响着联运货物的运输成本和运输效率,为进一步优化空铁联运方案,本文提出了基于“全货机+高铁货运专列”联运外部转运衔接模式,构建货运空铁联运衔接模型,设计货运空铁时刻表衔接方案及摆渡车调度方案,并设计遗传算法对模型进行求解,并进一步分析衔接成本及衔接时间。以某日虹桥机场T2航站楼和上海虹桥高铁站的部分实际时刻表数据为例,得到一个货运空铁联运衔接方案。对该方案进行仿真,结果表明:需设置3辆摆渡车在空铁之间完成货物的衔接作业,此时各摆渡车的工作量得到合理分配,且每批货物的衔接成本最小;在货运空铁联运总成本中,衔接成本占20%左右,且货运空铁联运在长途运输中成本优势更为明显;装卸货效率是影响货运空铁联运衔接时间的关键因素。从而为未来长途货运空铁联运运营提供参考。

    Abstract:

    Air-rail intermodal freight transportation offers a promising solution to address the increasing demand for high-value and time-sensitive goods. In the transformation of transport mode, the connecting link was affected by the transport cost and transport efficiency of combined transport goods to a certain extent. Based on the external transfer connection mode of "all-cargo aircraft + high-speed rail freight train", a model was constructed for optimizing the connection timetable and ferry scheduling scheme in air-rail intermodal freight transportation to further optimize the air-rail intermodality scheme,. To solve this model, an approach based on genetic algorithms was developed. Connection cost and connection time were further analyzed. The model and approach were tested in a real-world case of air-rail freight transportation using the timetable data of Hongqiao Airport T2 Terminal and Shanghai Hongqiao High-speed Railway Station on a specific day. The simulation results show that three ferry cars are needed to transport the goods in the air-rail connection. In this scheme, the workload of each ferry car is reasonably distributed, and the cost of each batch of goods is the smallest. The connection cost accounts for about 20% of the total cost, and the cost advantage of air-rail intermodality in long-distance transportation is more obvious. The efficiency of loading and unloading is the key factor affecting the connection time of air-rail intermodality. It can provide a guidance for the future operation of long-distance air-rail intermodality.
