摘要
利用多层Bayes方法研究了并联系统可靠性指标的近似置信限,给出了部件失效率,系统可靠度和平均寿命近似置信限的计算公式.最后,用随机模拟的方法对所得到的结果进行了分析,说明了该方法的合理性.
In this paper,the approximate confidence limits of the reliability for collateral system are studied by using the multiple-baye method.The paper sets up a formula to calculate approximate confidence limits of the failure rate,and the reliability function and average life.In the end,the results are compared and analysed by means of Monte-Carlo simulation.
