对两部件寿命服从Marshall-Olkin指数分布的串联系统和并联系统的可靠度进行了贝叶斯(Bayesian,Bayes)统计分析.在平方误差损失下,利用混合Metropolis-吉布斯抽样法给出了系统可靠度的Bayes估计.最后,通过模拟研究表明在串联系统和并联系统的可靠度估计中,Bayes估计要优于极大似然估计.
Bayesian Analysis of the Dependent Component System Based on Bivariate Exponential Distribution
A Bayesian(Bayes)procedure is presented for estimating the reliability of series system and parallel systems with two component lifetimes under Marshall-Olkin Exponential distribution.Under square error loss,Bayes estimation of the system reliability was proposed by mixed Metropolis-Gibbs sampling methods.Finally,through simulation studies,Bayes estimation for reliability of the series system and parallel systems is better than maximum likelihood estimation.
