摘要:

公铁联运是公路与铁路运输的有机结合,兼具二者的优势.公铁联运发展过程 中也存在一些问题,比如枢纽延误导致货物在枢纽停留过长时间,降低了其竞争力.本文 从战略层面出发,采用托运人关注的时间和费用因素构造了货物运输广义费用,并建立 了公铁联运网络上的运输方案选择模型,用于定量分析枢纽延误对公铁联运竞争力的影 响,为管理者提供决策支持.算例结果表明:附加值低的货物随着枢纽能力增大,采用公铁 联运的货物比重增加十分明显,而附加值高的货物采用公铁联运的比重并不会随枢纽能 力增加而大幅增加,另外,枢纽能力逐渐增加的过程中,首先吸引附加值较低的货物,再 吸引附加值较高的货物.

Abstract:

Hubs delay which may result in exceeding the deadline of goods damages the competitiveness of rail- road intermodal transport, although intermodal transport inherits the advantages of rail and road transport. From the perspective of strategic level, we model the choice of transport schemes on rail- road intermodal network, considering the two factors of transport time and transport fares concerned by shippers. This model can be used to analyze the impacts of hubs delay on rail- road intermodal network quantificationally, and give managers a decision support. Numerical example analysis shows that the competitiveness of rail- road intermodal transport for lower value goods increases significantly with hubs’ capacities increasing, but not significantly for higher value goods. The higher value that the goods possess, the higher capacity is needed to improve the competitiveness of intermodal for these goods.

Key words: integrated transportation, competitiveness, stochastic user equilibrium, intermodal transport, value of time
