摘　　要：针对提高人机系统设计的可靠性,将事故树分析方法应用到人机系统设计可靠性分析中去,从人的角度对人机系统设计的可靠性进行了事故树分析,首先找出了事故树的最小径集,然后又分别从结构重要度、概率重要度、关键重要度等方面对影响人机系统可靠性的基本事件进行了分析研究,找出了影响人机系统可靠性的主要因素,为人机系统产品的设计生产提供了更多的参考。研究结果表明,在影响人机系统设计可靠性的因素中,由设计缺陷导致的人因失误是影响系统可靠性的关键因素。In order to solve the problem of improving the reliability of man-machine system design,the fault tree analysis method was applied to the human reliability analysis of system design,the reliability of man-machine system design by fault tree was analyzed from the human point.Firstly the minimal path sets of the fault tree were identified.The basic events which are impact on the reliability of man-machine system were analyzed,from the importance of structure,the probability importance,critical importance.The main factors that affect the man-machine system reliability were identified,more information was provided to product design for the production of man-machine system.The results show that human errors caused by the design are the key factors affecting system reliability,among the factors that affect the reliability of man-machine system design.
