A CAPABILITY INDEX FOR MULTIPLE PROCESS STREAMS

Quality Engineering, 1999
The capability for each separate stream of a process having multiple process streams can be calculated by applying conventional capability metrics such as Cp or Cpk. Because the streams typically have dissimilar averages and standard deviations, the Cpk..

A process capability index for simple linear profile

The International Journal of Advanced Manufacturing Technology, 2012
In some cases, the quality of a process or a product is characterized by a linear regression model which is also called a linear profile. Process capability index is an important concept in statistical quality control and measures the ability of a process to manufacture products that meet certain specifications.

Capability index of a complex-product machining process

International Journal of Production Research, 2011
A complex product often requires a high machining precision. This is often achieved by a close-loop machining process to be carried out in several stages, and the measurements, fixture adjustments, and feedback or feed-forward control are inserted after each of these stages.

A new t-chart using process capability index

Communications in Statistics - Simulation and Computation, 2017
Control charts play a vital role to enhance the efficiency of the manufacturing process. In many situations, the quality characteristic of interest to be monitored follows a non-normal distribution...

Viability and capability indexes for multiresponse processes

Journal of Applied Statistics, 1998
The viability index Vr is introduced as an intuitively appealing measure of the capability potential of a process. It is related to the well-known index Cp but has some advantages over it. The statistical properties of Vr are readily obtainable and, unlike Cp, it extends naturally to multi-response processes.

New generalization of process capability index Cpk

Journal of Applied Statistics, 1998
Summary The process capability index Cpk has been widely used in manufacturing industry to provide numerical measures of process potential and performance. As noted by many quality control researchers and practitioners, Cpk is yield-based and is independent of the target T.

A mixed control chart using process capability index

Sequential Analysis, 2017
ABSTRACTControl charts are considered as a compulsory tool for the monitoring and improvement of the quality of products. The commonly used attribute and the variable control charts are unsatisfactory for process monitoring. To overcome this difficulty, we proposed a monitoring scheme that is an improved technique based on the joint merits of the ...

Fitting Generalized Gaussian Distributions for Process Capability Index

2018
The design process of integrated circuits (IC) aims at a high yield as well as a good IC-performance. The distribution of measured output variables will not be standard Gaussian anymore. In fact, the corresponding probability density function has a more flat shape than in case of standard Gaussian. In order to optimize the yield one needs a statistical
