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 ...
Synthetic control charts with two-stage sampling for monitoring bivariate processes
(2007-01-01)
In this article, we consider the synthetic control chart with two-stage sampling (SyTS chart) to control bivariate processes. During the first stage, one item of the sample is inspected and two correlated quality characteristics ...
Control charts for monitoring the mean vector and the covariance matrix of bivariate processes
(Springer London Ltd, 2009-12-01)
In this article, we propose new control charts for monitoring the mean vector and the covariance matrix of bivariate processes. The traditional tools used for this purpose are the T (2) and the |S| charts. However, these ...
Monitoring bivariate processes
(2009-09-01)
The T2 chart and the generalized variance |S| chart are the usual tools for monitoring the mean vector and the covariance matrix of multivariate processes. The main drawback of these charts is the difficulty to obtain and ...

A Single Statistic for Monitoring the Covariance Matrix of Bivariate Processes
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
In this article, we present a new control chart for monitoring the covariance matrix in a bivariate process. In this method, n observations of the two variables were considered as if they came from a single variable (as a ...

Synthetic charts to control bivariate processes with autocorrelated data
(2016-07-01)
In this study, we propose the use of simultaneous Xcharts to control bivariate processes with autocorrelated data. The first set of Xcharts is side-sensitive with regard to the same variable (SV Xcharts) and the second one ...
