摘    要:
文章讨论了当过程不满足正态性假设的情形下过程能力指数的近似置信限,并以Weibull分布为例给出了指数C′_(pm)的近似置信区间的具体形式和假设检验的检验统计量。最后给出了模拟验证。

关 键 词:过程能力指数  极大似然估计  置信限

Abstract:
This paper discusses the approximate confidence limits of process capability indices for non-normal process distributions,and obtains the approximate confidence limits of C′_(pm) as well as the test statictics of hypothesis for Weibull process distributions.Finally a simulation is conducted.
Keywords:process capability indices  maximum likelihood estimate  confidence limits
