Process Capability Indices

A solid, rigorous, yet comprehensible analysis of process capability indices, this work bridges the gap between theoretical statisticians and quality control practitioners, showing how an understanding of these indices can lead to process improvement. Content: Front Matter....Pages i-x Introduction....Pages 1-36 The basic process capability indices: Cp, Cpk and their modifications....Pages 37-85 The Cpm index and related indices....Pages 87-134 Process capability indices under non-normality: robustness properties....Pages 135-177 Multivariate process capability indices....Pages 179-201 Back Matter....Pages 203-212 This book clarifies the statistical meaning of process capability indices by presenting the theory to investigate the properties of various indices available in the literature and to convince practitioners of the advisability of representing estimates of process capability by a pair of numbers. A comprehensive analysis of the process capability indexes, a new tool for judging potentials of a manufacturing process under statistical control. The book attempts to bridge a gap between theoreticians who developed the theory and the quality control practitioners who apply the techniques
