摘　　要：利用广义推断方法研究了工作时间服从对数正态分布且参数皆未知,维修时间服从逆高斯分布情形下,可修系统稳态可用度的广义置信区间估计问题.模拟结果表明,用该法构造的广义置信下限在样本量较小时有较好的表现,且随着样本量增大置信下限越来越精确,在模拟的各种样本数量情形下,经验覆盖率都非常接近于名义水平.Generalized confidence interval of steady state availability of a repairable system was studied through Weerahandi＇s generalized inference method.The repairable system was under lognormal operating time with unknown parameters and inverse Gaussian repair time.The simulation results demonstrate that the generalized confidence intervals based on generalized p-value method have satisfactory performance in terms of empirical coverage probability.
