(X)OVER-BAR CHARTS WITH VARIABLE SAMPLE-SIZE
(Amer Soc Quality Control-asqc, 1994-07-01)
The usual practice in using a control chart to monitor a process is to take samples of size n from the process every h hours This article considers the properties of the XBAR chart when the size of each sample depends on ...

VSSI (X)over-bar charts with sampling at fixed times
(Marcel Dekker Inc, 1998-01-01)
A standard (X) over bar chart for controlling the process mean takes samples of size no at specified, equally-spaced, fixed-time points. This article proposes a modification of the standard (X) over bar chart that allows ...

The Variable Sample Size (X)over-bar Chart with Estimated Parameters
(Wiley-Blackwell, 2012-11-01)
The VSS X chart, dedicated to the detection of small to moderate mean shifts in the process, has been investigated by several researchers under the assumption of known process parameters. In practice, the process parameters ...
Joint (X)over-bar and R charts with two-stage samplings
(Wiley-Blackwell, 2004-11-01)
When joint (X) over bar and R charts are in use, samples of fixed size are regularly taken from the process, and their means and ranges are plotted on the (X) over bar and R charts, respectively. In this article, joint (X) ...

Joint (X)over-bar and R charts with variable sample sizes and sampling intervals
(Amer Soc Quality Control-asqc, 1999-10-01)
Recent studies have shown that the (X) over bar chart with variable sampling intervals (VSI) and/or with variable sample sizes (VSS) detects process shifts faster than the traditional (X) over bar chart. This article extends ...
