论文摘要
为了减少碳排放，相关政府部门鼓励铁路运输将道路货运更多。在中国货运系统中，道路运输通常负责短距离的货运或高价值的货运。为了将更多高价值的货运从高速公路转移到铁路，除了铁路的运输费用在道路上具有优势，运输时间也具有某些竞争力。因此，对于铁路，提供具有竞争力的货运火车产品至关重要。在这种情况下，根据将道路和铁路运输模式同时考虑的基础，在此工作中设计了一种优化铁路快车网络的多目标编程模型。优化的目的是最大程度地减少铁路火车的运营成本，并最大程度地利用铁路运输收入。在具有给定的快速火车服务集的网络中，可以在分配高增值货物时使用全有或无需（AON）方法或logit模型。在这项工作中研究了这两种流程分配模式。
In order to reduce the carbon emission, the related government departments encourage road freights to be transferred more by railway transportation. In China freight transport system, the road transportation is usually responsible for the freights that are in a short distance or the ones with high value-added. To transfer more high value-added freights from highway to railway, except the transportation expenses of railway have an advantage over the road, the transportation time is of certain competitive force as well. Therefore, it is very essential for railway to provide freight train products that are of competitive power. Under such circumstance, a multi-objective programming model of optimizing the rail express train network is devised in this work on the basis of taking both road and railway transportation modes into account. The aims of optimization are to minimize the operation costs of rail trains, and to maximize the railway transport revenue. In a network with a given set of express train services, either the all-or-nothing (AON) method or the logit model can be employed when assigning high value-added freights. These two flow assignment patterns are investigated in this work.
