在逐步增加的Ⅱ型截尾模型下,研究部件寿命服从双参数指数分布的冷贮备串联系统可靠性指标的Bayes估计。在超参数未知的情形下,分别在平方损失(SE),LINEX损失和熵(General Entropy,GE)损失函数下给出两个参数及可靠性指标的Bayes估计;对于超参数的确定,给出一种新的方法;最后利用随机模拟方法进行比较,并对结果进行了讨论。
The Bayes estimator of the reliability performance for cold standby series system are derived under the progressively type-II censored samples. Bayes estimators are obtained by using squared error (SE), LINEX and the general entropy loss function. With respect to the value of the unknown hyper-parameter, a new method is given to estimate the hyper-parameter value. At last, some numerical results are presented by using Monte-Carlo simulation.
