基于分位数过程能力指数的Bootstrap置信区间

Bootstrap Confidence Intervals of Quantile-based Process Capability Indices

讨论了基于分位数过程能力指数的Bootstrap置信区间,并以Taguchi指数C′p m为例,在过程服从Weibull分布情况下给出了指数C′p m的Bootstrap置信区间的求法,通过模拟研究验证了该方法的可行性.

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.
