Multivariate process capability index based on coefficient of variation 基于差异系数的多元过程能力指数
This method is also used to evaluate and select the suppliers in the global and dynamical angle . this paper comes up with a new algorithm of multivariate pci based on coefficient of variation ( cv ) aiming at the flaw of the principle component analysis 其次针对基于主成份分析的思想计算多元过程能力指数的不足,本文提出了基于差异系数的多元过程能力指数的计算方法,实例证明该方法更加符合实际。
