失效率的综合E-Bayes估计

Synthetic Expected Bayesian Estimation of the Failure Rate

该文提出了可靠性参数的一种新估计方法——综合E-Bayes估计法.在无失效数据情形下给出了失效率的E-Bayes估计的定义,并给出了失效率的E-Bayes估计.在引进失效信息后,给出了失效率的E-Bayes估计,并在此基础上给出了失效率和其它参数的综合E-Bayes估计.最后,结合实际问题进行计算,结果表明该文提出的方法可行且便于应用.

The paper gives a new estimation method of reliability parameters, which is named as “synthetic expected Bayesian estimation method”. In the case of zero-failure data, the definition of expected Bayesian estimation and the expected Bayesian estimation of failure rate are given. After introducing failure information, the expected Bayesian estimation of failure rate is given, the synthetic expected Bayesian estimation for failure rate and Other reliability parameters are given also on the base. Finally, calculations are performed regarding to a practical problem, which show that the synthetic expected Bayesian method is feasible and easy to operate.
