A variable sampling plan using generalized multiple dependent state based on a one-sided process capability index

Communications in statistics. Simulation and computation, 2019
In this manuscript, a sampling plan based on one-sided process capability index is designed using the generalized multiple dependent state (GMDS) sampling.

Sampling Plans Using Process Capability Index (PCI)

2019
The Process Capability Index (PCI) has been widely used in the industry to manage the quality of product. It has become an important tool of Statistical Process Control (SPC) for the continuous improvement of the quality. The PCIs are used to make a relationship between process quality and specifications limits and take into consideration both ...

Asymptotic and Bootstrap Confidence Intervals for the Process Capability Index cpy Based on Lindley Distributed Quality Characteristic

American Journal of Mathematical and Management Sciences, 2019
SYNOPTIC ABSTRACT Process capability indices (PCIs) have been widely applied in measuring product potential and performance. It is of great significance to quality control engineers, as it quantifies the relation between the actual performance of the ...

A process capability index sensitive to skewness

Journal of Statistical Computation and Simulation, 1995
A new process capability indexCs , is proposed which extends the most useful index to date, the Pearn-Kotz-Johnson Cpmk , by not only taking into account that the process mean may not lie midway between the specification limits and incorporating a penalty when the mean deviates from its target, but also incorporating a penalty for skewness.

A practical implementation of the process capability index

Journal of Statistics and Management Systems, 2007
Summary: The generalization \(C_{pm}^{\prime\prime}\), a modification of the process capability index \(C_{pm}\), not only takes the proximity of the target value into consideration but also takes into account the asymmetry of the specification limits.

Determination of multiple dependent state repetitive group sampling plan based on the process capability index

Sequential Analysis, 2019
In this article, we propose a sampling plan called a multiple dependent state repetitive group sampling plan for variable inspection based on the process capability index Cpk.

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.
