Abstract: The multivariate process capability indices (MPCI) are widely applied in product quality analysis. However, there is no efficient method for solving such a problem. By combining rough set and quartile method, a novel approach is proposed to solve this problem in this paper. A case study is presented and the results demonstrate the effectiveness of the proposed approach.

Key words: multivariate process capability indices (MPCI), rough set, quartile method
