A new process capability index for non‐normal distributions

Chen, Jann‐Pygn; Ding, Cherng G. - In: International Journal of Quality & Reliability Management 18 (2001) 7, pp. 762-770

Many process capability indices have been proposed to measure process performance. In this paper, we first review C p , C pk , C pm and C pmk , and their generalizations, C Np , C Npk , C Npm and C Npmk , and then propose a new index S pmk for any underlying distribution, which takes into...

Managing service quality: applying utility theory in the prioritization of service attributes

Li, Y.N.; Tan, K.C.; Xie, M. - In: International Journal of Quality & Reliability Management 20 (2003) 4, pp. 417-435

The ability of a company to achieve excellence in service quality depends on the determination of service attributes and their desired levels. It depends also on the prioritization of service attributes, using appropriate quality improvement indices, in a consistent manner within the constraints...
