| 摘 要： | 非正态过程能力指数的估计问题是目前过程能力研究中的一个热点。在简要总结该领域现有研究成果的基础上，针对目前研究中存在的不足，利用样本百分位数法和Shapiro-wilk统计检验原理，提出基于Johnson转换体系的非正态过程能力指数估算方法与实现步骤。最后结合具体实例对上述理论和方法进行应用分析，研究表明该方法比其他方法计算简便，结果更精确可靠。

| Abstract: | The estimation of non-normal process capability index is popular in the field of process capability analysis. After briefly reviewing the results in this field, a complete procedure and a method of estimating non-normal process capability index based on Johnson system of transformations was presented, using the method of sample percentile and Shapiro-Wilk test. Then a case study was given, which proved that this method is much better than others in calculation complexity and exactness. |
