The non-central chi-square chart with two-stage samplings
(Elsevier B.V., 2006-05-16)
In this paper, we consider the non-central chi-square chart with two stage samplings. During the first stage, one item of the sample is inspected and, depending on the result, the sampling is either interrupted, or it goes ...

Monitoring process mean and variability with one non-central chi-square chart
(Carfax Publishing, 2004-12-01)
Traditionally, an (X) over bar -chart is used to control the process mean and an R-chart to control the process variance. However, these charts are not sensitive to small changes in process parameters. A good alternative ...

An adaptive chart for monitoring the process mean and variance
(Wiley-Blackwell, 2007-11-01)
Traditionally, an (X) over bar chart is used to control the process mean and an R chart is used to control the process variance. However, these charts are not sensitive to small changes in the process parameters. The ...

Monitoring the process mean and variance using a synthetic control chart with two-stage testing
(Taylor & Francis Ltd, 2009-01-01)
In this paper, we propose a synthetic control chart with two-stage testing (SyTS chart) to control the process mean and variance. As in the case of Shewhart control charts, samples are taken from the process at regular ...
A synthetic control chart for monitoring the process mean and variance
(2006-04-10)
Purpose - The aim of this paper is to present a synthetic chart based on the non-central chi-square statistic that is operationally simpler and more effective than the joint X̄ and R chart in detecting assignable cause(s). ...
