基于椭球体规格的多元过程能力指数的研究

Multivariate statistical process capability index based on ellipsoid volume

文中提出一种基于椭球体规格的过程能力指数,给出了其理论模型和计算方法,分析了其特点,并利用一组经典数据进行了实证分析,表明该过程能力指数的可行性。

A new kind of PCIs based on the volume of ellipsoid was put up.The theoretical models and computing methods were expounded,and its characters were analyzed.A set of classic data was used to test and prorse.The result showed the feasibility of this new kind of PCI.
