客运专线相关旅客列车开行方案研究

Research on Passenger Train Plans for Dedicated Passenger Traffic Lines

通过分析铁路客运专线的相关收益及费用,从铁路运输企业和旅客两方面的利益出发建立了客运专线相关旅客列车开行方案的多目标优化模型,提出了优化旅客列车开行方案的求解方法。所提出的换乘多种类别列车的疲劳恢复时间计算公式、不同消费层次选择不同类别列车的思想、列车开行数量的计算式、列车的吸流原则、确定列车类别的动态规划方法等都贴切反映了铁路客运组织和客运市场的相关规律。该方法在客运专线预可行性研究中得到了成功的应用,求解路网规模为60个车站的旅客列车开行方案仅需100s左右时间,并获得了满意的结果。

In this paper, a multi-object optimum model of passenger train plans for dedicated passenger traffic lines is established by balancing benefits of both railway transportation corporations and passengers, and a method to solve optimization of passenger train plans is given. The included restoring time function where a passenger transfers among several kinds of passenger trains, the ideas that differeat consume-level passengers choose different kinds of passenger trains, the formula to calculate the number of running trains , the principle of a train absorbing passengers and the dynamic programming to determine the train classification, all reflect the laws of the railway passenger traffic organization and market. The method has been applied in prefeasibility study of dedicated passenger lines successfully. It needs just about 100 seconds to calculatea passenger train plan with 60 stations and the result is satisfactory.
