Monitoring capability indices using run rules

Journal of Quality in Maintenance Engineering, 2009
PurposeThe purpose of this paper is propose a methodology for monitoring industrial processes that cannot be stabilized, but are nevertheless capable.Design/methodology/approachThe proposed procedure uses the CP(u,v) family of capability indices proposed by Vännman (including the indices CPK, CPM, CPMK) combined with one‐sided two‐out‐of‐three and ...

Probability-Based Process Capability Indices

Communications in Statistics - Simulation and Computation, 2009
This 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

Confidence Bounds for Capability Indices

Journal of Quality Technology, 1992
Capability indices compare the actual performance of a manufacturing process to the desired performance. In practice these indices are estimated using sample data, often with quite small sample sizes. Thus, it is of interest to obtain confidence limits ..

Process Capability Indices

Journal of Quality Technology, 1986
The capability indices Cp, CPU, CPL, k and Cpk are presented and related to process parameters. These indices are shown to form a complementary system of measures of process performance, and can be used with bilateral and unilateral tolerances, with or ..

Dynamic Process Capability Indices

Asian Journal on Quality, 2002
Process capability indices as an important kind of indices are intended to provide single‐number assessments of the inherent process capability to meet specification limits on quality characteristic(s) of interest. In this paper the condition for the application of process capability indices is analyzed.

On Generalizing Process Capability Indices

Quality Technology & Quantitative Management, 2010
AbstractA 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-

Squared Error Loss of Process Capability Indices

Economic Quality Control, 2001
In this paper, we extend Johnson's work (2) of formulating the relationship between process capability indices (PCI) and expected squared error losses. Moreover, a comparison is made between the expected squared error loss of PCI under the specified capability index value.

Fit capability indices and their applications

International Journal of Production Research, 1996
Current methods for assuring assembly accuracy are mainly based on process capabilities and specification limits of each mating part without considering the interrelationship between the distribution of fit size and those of mating sizes (typically, hole and shaft).
