Sequential testing of process capability indices

Journal of Statistical Computation and Simulation, 2012
A Process Capability Index (PCI) is a numeric summary that compares the behaviour of a product or process characteristics with engineering specifications. We propose a sequential procedure for testing whether two processes are equally capable by using the PCI (C pm).

Basic Process Capability Indices: An Expository Review

International Statistical Review, 2008
Summary A review of the four basic process capability indices has been made. The interrelationship among these indices has been highlighted. Attention has been drawn to their drawbacks. The relation of these indices to the proportion nonconforming has been dwelt upon and the requirement of the adequate sample size has been emphasized.

Process capability indices

The thesis is introduced and studied the initially capability indices and their youngest indices which appeared for the improvement of capability indices. The majority of the work refers to one-dimensional characteristics of normal distribution, but there is an important reference in multi-dimensional of normal data. In the first chapter we will define

Estimating process capability indices of multivariate nonnormal processes

The International Journal of Advanced Manufacturing Technology, 2010
The capability analysis of production processes where there are more than one correlated quality variables is a complicated task. The problem becomes even more difficult when these variables exhibit nonnormal characteristics. In this paper, a new methodology is proposed to estimate process capability indices (PCIs) of multivariate nonnormal processes ...

Process capability indices for a regularly adjusted process

International Journal of Production Research, 2002
Process capability indices are widely used in industry to achieve and maintain a high-quality level of manufactured items. The successful application of process capability indices requires the process to be stationary. This is not the case for trended processes with regular adjustment, which are very common in manufacturing processes.

An application of non-normal process capability indices

Quality and Reliability Engineering International, 1997
Numerous 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.

Multivariate Process Capability Indices (MPCI)

2012
In this chapter the most recognized multivariate process capability indices are presented. The first section approaches the computation of these indices in R, and the next ones are dedicated to the indices based on ratios of the volume tolerance region to a process region such as Taam et al. (J Appl Stat 20:339–351, 1993), Shahriari et al. (Proceedings
