| Abstract: | This paper discusses the confidence intervals of process capability indices.The Bootstrap method of constructing the confidence intervals of quantile-based process capability indices is proposed,and a study based on simulation is taken to evaluate the performance of four kinds of Bootstrap confidence intervals of C′pm for Weibull process distribution.The results show that the Bootstrap method is feasible and effective. |
