A combined npx X control chart to monitor the process mean in a two-stage sampling
(Quality and Reliability Engineering International, 2023)
A side-sensitive synthetic chart combined with an X chart
(Taylor & Francis Ltd, 2014-06-03)
The synthetic chart combined with an chart (Synthetic- chart) signals when a sample point falls beyond the control limits or when a second point, not far from the first one, falls beyond the warning limits, no matter whether ...
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 ...

An adaptive chart for monitoring the process mean and variance

A side-sensitive synthetic chart combined with a VSS X¯ chart
(2016-01-01)
In independent investigations, the variable sample size (VSS) scheme and the side-sensitive synthetic (SS) rule proved to reduce the delay with which the X¯ chart signals. Based on these findings we investigate the X¯ ...

The Shewhart attribute chart with alternated charting statistics to monitor bivariate and trivariate mean vectors
(2018-08-01)
In this article, we combined the Alternated Charting Statistic (ACS) scheme with the traditional attribute np chart to control mean vectors of bivariate and trivariate normal processes. With the bivariate ACS scheme in use ...
Simultaneous Univariate X-bar Charts to Control Bivariate Processes with Autocorrelated Data
(2015-12-01)
In this article, we consider the simultaneous univariate X-bar charts (SU X-bar charts) for samples of n bivariate observation vectors that are not only cross-correlated but also autocorrelated. The cross-covariance matrix ...
