The New Nino Capability Index for Dynamic Process Capability Analysis

open access: yesQuality and Reliability Engineering International, 2013
The process capability analysis is a crucial activity to evaluate if the process outcome meets the design specifications. Classically, such analysis is performed by verifying the in‐control condition of the process and evaluating suitable capability indices, by assuming the process in‐control steady‐state condition.

A Bayesian estimator of process capability index

Journal of Statistics and Management Systems, 2006
Abstract Process capability and process performance index studies are to assess a process relative to specification criteria. Quantification of this measurement is often reported using various indices. One such index namely Cp has been considered in this paper.

A Note on the Multivariate Process Capability Index MCpm

open access: yesQuality and Reliability Engineering International, 2013
Important features of multivariate process capability indices are comparability, interpretability and ease of implementation. When poor process capability is indicated by an index, the user should determine why the process is incapable (e.g. excessive variability or off‐target process mean).

Measuring process capability index C pmk with fuzzy data and compare it with other fuzzy process capability indices [PDF]

open access: yesExpert Systems With Applications, 2011
The index Cpmk is a well-known loss-based process capability index. It can reveal more information about the location of the process mean compared with other classic process capability indices.

Properties of Estimators of the Process Capability Index

Communications in Statistics - Simulation and Computation, 2012
The capability index is designed for an in-control process with asymmetric tolerances. In this article, the density function of the natural estimator is derived. The expression is in terms of finite sum and only involves standard normal distribution. Four ensemble estimators for are proposed. A simulation study is conducted due to the complexity of the
