Constrained optimization model for the design of an adaptive (X)over-bar chart
(Taylor & Francis Ltd, 2002-09-01)
An economic-statistical model is developed for variable parameters (VP) (X) over bar charts in which all design parameters vary adaptively, that is, each of the design parameters (sample size, sampling interval and ...

Double-objective economic statistical design of the VP T-2 control chart: Wald's identity approach
(Taylor & Francis Ltd, 2014-10-01)
Research has shown that applying the T-2 control chart by using a variable parameters (VP) scheme yields rapid detection of out-of-control states. In this paper, the problem of economic statistical design of the VP T-2 ...
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 ...
Gráficos de controle de regressão beta robustos
(Universidade Federal de Santa MariaBrasilEngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de ProduçãoCentro de Tecnologia, 2019-02-19)
Control charts are the main tool of the statistical control process (SPC) to monitor and extract
information about a certain process. The usual control charts are built under the normality
assumption of the data or ...
