Γ部件冷贮备系统的可靠性分析

The reliability analysis of the Gamma component for cold standby system

文中运用极大似然法、Bayes方法、经验Bayes方法,给出了Γ部件冷贮备系统失效率、可靠度函数与平均寿命的点估计,并利用Monte-Carlo方法,对3种估计结果进行了模拟比较,结果表明经验Bayes估计整体上优于Bayes估计和极大似然估计。

Moment estimation of the failure rate,the reliability function and average life of the Gamma component for cold standby system are obtained by using the maximum likelihood estimation,the Bayesian estimation and the empirical Bayes estimation.The three estimation results are simulated and compared through the method of Monte-Carlo.The result suggests that empirical Bayes estimation is generally better than Bayesian estimation and Maximum likelihood estimation.
