在含有屏蔽数据的情况下,研究串联系统中BurrⅫ部件可靠性指标的估计问题.利用极大似然法给出了部件参数的极大似然估计,并分别在平方损失、LINEX损失和熵损失函数下,给出部件参数及可靠性指标的Bayes估计.最后利用Monte-Carlo随机模拟方法对各种估计结果进行了比较分析.
We derive the estimations of the reliability performances in the series system,which are based on masked system life test data and assumed to be BurrⅫdistributed.The MLE of the parameters are derived by using maximum likelihood method,and Bayes estimations are obtained under Squared Error, LINEX and General Entropy loss function.At last,some numerical results are discussed and compared by using Monte-Carlo simulation.
