摘要
利用可靠性框图法详细推导不同结构下平均失效概率的计算方法,给出安全相关系统安全功能的平均失效概率的计算过程,并通过实例对安全控制系统进行定量分析。
Evaluating techniques for average probability of failure in different architecture were derived by reliability block diagram, calculating procedure of average failure probability of safety function in safety-related system was given. Calculation method and evaluation procedure were demonstrated by instances.
