Probability-Based Process Capability Indices
Communications in Statistics - Simulation and Computation, 2009This article deals with alternative process capability indices (PCIs) to traditional basic PCIs C p , C pk , and C pm based on different fraction conforming type of probabilities. In view of various problems of constructing capability indices for univariate as well as multivariate set up, these alternative PCIs are very useful as compared to C p , C pk

Process capability indices and product reliability
Microelectronics Reliability, 2001Abstract This paper discusses process capability indices— C p and C p k , their underlying assumptions, and the relationships between process capability indices and product reliability. An actual case is presented to demonstrate this relationship.

Robust process capability indices
Omega, 1998Many organizations are mandating the use of process capability indices to measure and reduce variability. Managers may find the use of such indices as unreliable when the interaction of the dependency structure and outliers mask potential assignable causes of variation.

On Generalizing Process Capability Indices
Quality Technology & Quantitative Management, 2010AbstractA generalized process capability index, defined as the ratio of proportion of specification conformance (or, process yield) to proportion of desired (or, natural) conformance, has been developed. Almost all the process capabilities defined in the literature are directly or indirectly associated with this generalized index. Normal as well as non-

Process Capability Indices in Theory and Practice
Technometrics, 2000What is it all about? the avalanche the two basic, time-honoured process capability indices - Cp and Cpk first generation modification - Cpm and its clone relatives the benefit (or the curse) of normality and symmetry and how to get rid of it when necessary a superstructure and unified approach to process capability indices the dangerous but ...

An application of non-normal process capability indices
Quality and Reliability Engineering International, 1997Numerous process capability indices, including Cp, Cpk, Cpm, and Cpmk, have been proposed to provide measures of process potential and performance. In this paper, we consider some generalizations of these four basic indices to cover non-normal distributions. The proposed generalizations are compared with the four basic indices.

Generalized confidence intervals for process capability indices
Quality and Reliability Engineering International, 2006AbstractThe concept of generalized confidence intervals is used to derive lower confidence limits for some of the commonly used process capability indices. For the cases where approximate lower confidence limits are already available, numerical comparisons are made among the available approximations and the generalized lower confidence limit.
