基于层次分析法的列车折返能力影响因素分析

Analysis on influence factors of train reentrant ability based on analytic hierarchy process

为了对城市轨道交通折返能力影响因素中的定性问题进行综合定量评价与分析,确定折返过程中各影响因素的权重,运用层析分析法原理构建城市轨道交通折返能力影响因素AHP模型,为前期折返站的设计以及后期折返能力的优化设计提供参考依据。结果显示:从道岔类型、站停时间以及折返站型对折返站进行前期设计和后期优化,能较大幅度地提高折返能力。

In order to comprehensively evaluate and analyze the qualitative problems in the infuence factors of train reentrant ability of urban rail transit and determine the weight of the infuencing factors in the process of reentrant, the paper used analytic hierarchy process （AHP） to establish the AHP model of infuence factors on the reentrant ability of urban rail transit, provided a reference for the design of the prophase reentrant station and the optimal design of the later reentrant ability. The results show that the pre-design and post-optimization of the reentrant station from turnout type, stop time, and reentrant station can greatly improve the reentrant ability.
