摘要 利用逐步II型截尾样本,研究一种表决系统可靠性指标的估计问题。将经典统计方法和Bayes方法相结合,在平方损失下,推导出部件失效率、系统可靠度和平均寿命的经验Bayes估计。最后给出随机模拟例子,说明了该方法的正确性。 Based on progressively type-Ⅱ censored samples,the problems of estimating the reliability performances for a voting system are studied by using Bayes and MLE approaches.Under squared-error loss,the formulae to calculate empirical Bayes estimation of the failure rate,the reliability function and mean lifetime are given.Finally ,an illustrative Numerical example is examined by means of the Monte-Carlo simulation.
