摘　　要：雪深监测系统作为高速铁路防灾监控系统的重要组成部分,其可靠性直接影响监测系统对高速铁路雪情的监测。首先引入模糊理论和VIKOR法对传统的FMECA分析法进行改进,然后用改进后的FMECA法对雪深监测系统进行可靠性分析,最后根据雪深监测系统各故障模式危害性的VIKOR值,找出系统的薄弱环节,为提高雪深监测系统可靠性和日常维修提供技术支持。The reliability of snow depth monitoring system is used as an important part of the disaster prevention and safety monito-ring system of high-speed rail. Its reliability has a direct effect on the snow condition monitor of the high-speed train. This paper uses the the fuzzy theory and VIKOR method to improve the traditional FMECA method and uses the improved FMECA to do its reliability analysis and then finds out its weak links by improved FMECA, thus improving the reliability of snow depth monitoring system and providing technical support for the routine maintenance.
