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 ...

X̄ Charts with Variable Parameters
(1999-10-01)
Varying the parameters of the X̄ chart has been explored extensively in recent years. In this paper, we extend the study of the X̄ chart with variable parameters to include variable action limits. The action limits establish ...
