摘要
针对多部件的串联系统应力-强度模型可靠度的估计问题,利用多元Farlie-Gumbel-Morgenstern copula(FGM)函数或多元Clayton copula函数来度量变量之间的相关性,给出了在变量非删失或右删失情形下模型可靠度的非参数估计,并证明了估计量的渐近性质.数值模拟的结果表明该方法在有限样本下表现良好.
To estimate the reliability of a series system the stress-strength model with multiple components,we utilize the multivariate Farlie-Gumbel-Morgenstern(FGM)copula function or multivariate Clayton copula function to measure the correlations of variables.We obtained the nonparametric estimation for the reliability under no censored or right censored cases and verified the asymptotic properties of the resultant estimators.Simulation results show that the proposed method performs well in finite samples.
