【摘要】：在高速铁路初步成网、既有线运输能力得到不同程度释放的背景下,本文研究了铁路网最大货运发送量和流量分配的综合优化问题.文中以增长后的铁路网货运需求量来描述货运发送量,构建了符合铁路运输车流组织特点的多目标优化模型.模型的目标函数包括货运发送量的最大化和不同货运发送量情形下的流量分配成本最小化.同时考虑了单股货流增长量上限、车流走行具有树形径路特点、非重复径路的数学逻辑表达等约束条件.最后,基于相同算例数据对所构建模型及既有研究文献中的模型进行求解试验,分别得到两种模型下的铁路网最大货物发送量和流量分配方案,通过对比求解结果,验证了本文模型的有效性.
[Abstract]:Under the background of the initial netting of high-speed railway and the release of the capacity of the existing railway to varying degrees, this paper studies the comprehensive optimization of the maximum freight transport volume and flow distribution in the railway network. In this paper, the freight transport volume is described by the increasing freight demand of railway network, and a multi-objective optimization model is constructed, which accords with the characteristics of railway traffic flow organization. The objective function of the model includes the maximization of the freight volume and the minimization of the flow allocation cost in the case of different freight volumes. At the same time, the upper limit of the increase of single stock freight flow is considered. The train flow has the characteristics of tree-shaped path and the mathematical logic expression of non-repeated path, and so on. Finally, based on the data of the same example, the solution tests of the models constructed and the models in the existing research literature are carried out, respectively, and the maximum cargo delivery and flow distribution schemes of the railway network under the two models are obtained, and the results are compared. The validity of the model is verified.
