Estimating process capability indices of multivariate nonnormal processes
The International Journal of Advanced Manufacturing Technology, 2010The 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, 2002Process 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, 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.

Multivariate Process Capability Indices (MPCI)
2012In 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

Productive Systems Process Monitoring through Process Capability Indices [PDF]
, 2006 Process capability indices are widely used in process assessments and in evaluation of decisions for a continuous improvement of quality in manufacturing or service process. This paper provides a brief survey of the main capability indices. The paper also focalizes the process capability indices in order to determine their sensitivity to time changes ...
