Multivariate nonnormal process capability analysis
The International Journal of Advanced Manufacturing Technology, 2009There is a great deal of interest in the manufacturing industry for quantitative measures of process performance with multiple quality characteristics. Unfortunately, multivariate process capability indices that are currently employed, except for a handful of cases, depend intrinsically on the underlying data being normally distributed.

Lithographic process optimization using process capability analysis
SPIE Proceedings, 2003A capable process fulfills many requirements on e.g. depth of focus, exposure latitude, and mask error factor. This makes a full optimization complicated. Traditionally only a few parameters are included in the optimization routine, such as the focus-dose process window, while other parameters like the (NA,σ ) illumination conditions are fixed at a ...

Process capability analysis for a multi-process product
The International Journal of Advanced Manufacturing Technology, 2005In this paper, we propose a flow path to evaluate the process capability of an entire product composed of multiple process characteristics. There are six steps in the flow path. Whether process data comply with a normal distribution or a non-normal distribution, the flow path can be applied.

Process Characterization and Capability Analysis
2016The previous chapter dealt with tools for monitoring processes and detecting physical instabilities. The goal of using these is finding the source(s) of any process upsets and removing them, creating a process that is consistent/repeatable/ predictable in its pattern of variation.

Multiple streams process capability analysis chart
Journal of Information and Optimization Sciences, 2008Process capability plots with single stream process have earlier been discussed by Deleryd and Vannman (1999); however multiple streams process often exists in practice. In the present paper, we introduce a new control chart, called the multiple streams process capability analysis (MSPCA) chart, using the multiple streamsyield index proposed by Wang et

Process Capability Analysis with R
2012Capability analysis is a very important part of the Measure phase in a Six Sigma project. It is also part of classical statistical process control. Through capability analysis we can measure how the process performance fits the customer/client requirements.

Process capability analysis—a robustness study
International Journal of Production Research, 1993Abstract The robustness of two popular process capability ratios, Cp and Cpk, when the random process being observed departs from normality is analysed. The distributions of estimated process capability ratios are derived and used as a basis for validation of large-scale simulation studies in an examination of departures from normality.
