表决系统可靠性指标的近似置信限比较

The Approximate Confidence Limit of the K/N(G) System's Reliability Performance

利用E-Bayes和多层Bayes方法对定时截尾试验数据下表决系统的可靠性指标进行估计,得到了部件失效率、系统可靠性和系统平均寿命的E-Bayes近似置信限和多层Bayes近似置信限,并利用蒙特卡罗方法进行模拟比较,结果表明,多层Bayes方法比E-Bayes方法更具优势.

An estimation is made of the K/N（G） system＇s reliability performances based on E-Bayes and multiple Bayes method, achieving the approximate confidence limits of the failure rate, reliability function and average life. Then, the results are compared with Monte-Carlo simulation. The multiple Bayes method shows a distinct advantage over E-Bayes method.
