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 pprocess mean and variance
(2006-12-01)
In this article, we consider the synthetic control chart with two-stage sampling (SyTS chart) to control the process mean and variance. During the first stage, one item of the sample is inspected; if its value Xl is close ...
Performance of balanced two-stage empirical predictors of realized cluster latent values from finite populations: A simulation study
(ELSEVIER SCIENCE BV, 2008)
Predictors of random effects are usually based on the popular mixed effects (ME) model developed under the assumption that the sample is obtained from a conceptual infinite population; such predictors are employed even ...
Economic design of two-stage (X)over-bar charts: the Markov chain approach
(Elsevier B.V., 2005-01-28)
When the (X) over bar chart is in use, samples are regularly taken from the process, and their means are plotted on the chart. In some cases, it is too expensive to obtain the X values, but not the values of a correlated ...

Bivariate control charts with double sampling
(Routledge Journals, Taylor & Francis Ltd, 2008-01-01)
In this article, we consider the T(2) chart with double sampling to control bivariate processes (BDS chart). During the first stage of the sampling, n(1) items of the sample are inspected and two quality characteristics ...

Monitoring the process mean with an ATTRIVAR chart
(2020-01-01)
In this article, we propose an ATTRIVAR chart to control the process mean. With the ATTRIVAR chart, the sampling is performed in two stages, collecting attribute and variable sample data from the same sample (attribute ...
