基于灰色关联的城市轨道网络列车运行计划综合评价

Comprehensive evaluation of train plan on urban rail network based on grey correlated analysis

城市轨道交通网络列车运行计划的综合评价不仅需衡量各条线路列车运行质量,还应着重考虑各线间列车运行接续质量。本文首先从服务质量、线间协调、首末班车协调、高峰期站台客流饱和、抗干扰性以及技术性6个方面构建城市轨道网络列车运行计划综合评价的指标体系;其次在分别采用层次分析法与熵值法确定各评价指标主观与客观权重的基础上,通过线性组合主观与客观权重而获得各评价指标权重,进而通过计算灰色关联系数确定各评价方案的灰色关联度来实现路网列车运行计划方案选优。

While the train operation plan on urban rail transit network is evaluated, it is not only needed to measure train organization quality of each lines, but also to focus on train connecting quality among lines. Firstly, the comprehensive evaluation indexes of train operation plan were built from service quality, train running coordination among lines, the first and last train coordination, passenger saturated of platform, anti - jamming, as well as technicality. Secondly, the objective weighting was calculated by using the analytic hierarchy process while the subjective weighting was computed by using entropy method. Then the weighting of each index was acquired by the linear combination of the objective weighting and subjective weighting. Thereby the gray relational model was established to achieve a comprehensive evaluation train operation plan of the urban rail network.
