基于粗糙集和遗传算法的驼峰超速连挂事故分析

驼峰超速连挂事故受多种因素影响，运用粗集相关理论分析线路、调速设备和车流等事故因素，引入遗传算法进行属性约简，得到包括驼峰设计和运营线路纵断面变化、调速设备合理配置和新型重载车辆等几个关键影响因素。通过对影响因素分析能够在决策时给出科学依据，以此降低或避免事故发生的可能性。

Analysis on Over-Speed Coupling Accidents on Hump Based on Rough Set and Algorithm

Over‐speed coupling accidents were caused by many integrated factors on the hump .The paper was to make use rough set to analyze the affects of tracks ,speed control equipment and rolling stock . T hen it deleted redundant causes of accidents by genetic algorithm ,obtained the key influence factors of the design and the operation of the hump :the unreasonable vertical section of the hump , the braking capacity of the hump equipment ,and the newly‐built heavy‐haul cars . Through the analysis of these factors can give a more scientific basis in decision‐making ,in order to reduce or avoid the possibility of accident happen again .
