摘要
为了对系统可靠性进行全面分析,消除基于"人-机-环境"三方面可靠性分析结果的不兼容且不易叠加,以至于无法评判系统整体可靠性的问题,提出系统因素可靠性分析的思想.将使系统可靠性改变的"人-机-环境"原因作为因素考虑,进而得到系统可靠性的统一表示方式.提出了作为系统因素可靠性分析方法所要满足的三个条件:因素影响的兼容叠加性、定量分析性、动态适应性.对空间故障树SFT理论方法作为系统因素可靠性分析方法的可行性进行了论证.结果表明SFT完全满足作为该分析方法的三个条件.并简要介绍了目前SFT所具备的方法和数据流.
In order to analyze the reliability of the system comprehensively,eliminating the problem that can＇t judge the reliability of the overall system,because the results of reliability analysis are compatible and combination considering the three aspects of people-machine-environment,the system reliability factor analysis is proposed,and a unified representation of system reliability is obtained. The three conditions are proposed to meet the system factor reliability analysis,including the factors affecting compatibility and combination,quantitative analytical and dynamic adaptability. Feasibility to the space fault tree（ SFT） theory as a method for the system factor reliability analysis is demonstrated. The results show that the SFT satisfies the three conditions of the analysis method,and the current SFT possess methods and data streams are briefly described.
