可靠性工程中参数的E-Bayes估计法及其应用

摘要

随着科学和技术的进步需要有效地改进工业产品可靠性的评估方法.本文提出了可靠性工程中参数估计的一种方法--E-Bayes估计法.给出了失效概率的E-Bayes估计的定义,在此基础上给出了失效概率的E-Bayes估计和多层Bayes估计,并给出了E-Bayes估计的性质--E-Bayes估计和多层Bayes估计的关系.最后,结合实际问题进行了计算,结果表明本文提出的E-Bayes估计法可行且便于工程应用.%A evaluation method of reliability of industrial products needs to be improved effectively with the advance of science and technology.E-Bayesian estimation method of parameter estimation in reliability engineering was proposed.Based on the definition of E-Bayesian estimation of the failure probability,the formulas of E-Bayesian estimation and hierarchical Bayesian estimation of the failure probability were provided,and the characteristic of the E-Bayesian estimation,i.e.the relation between E-Bayesian estimation and hierarchical Bayesian estimation,was discussed.The calculated results by the practical problem show that the proposed E-Bayesian estimation method is feasible,and convenient in engineering application.
