摘要
Process capability indices haze been widely used in the manufacturing industry, providing numerical measures on process precision, process accuracy, and process performance. Capability measures for processes with a single characteristic haze been investigated extensively. However, capability measures for processes with multiple characteristics are comparatively neglected. In this paper. inspired by the approach and model of process capability index investigated by K. S. Chen et al. (2003) and A. B. Yeh et al. (1998), a note model of multivariate process capability index based on non-conformity is presented. As for this index, the data of each single characteristic don't require satisfying normal distribution, of which its computing is simple and particioners will not fell too theoretical. At last the application analysis is made.
