X̄ chart with variable sample size and sampling intervals
(1997-04-01)
Recent theoretical studies have shown that the X̄ chart with variable sampling intervals (VSI) and the X̄ chart with variable sample size (VSS) are quicker than the traditional X̄ chart in detecting shifts in the process. ...

(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 ...

Joint X̄ and R Charts with Variable Sample Sizes and Sampling Intervals
(1999-10-01)
Recent studies have shown that the X̄ chart with variable sampling intervals (VSI) and/or with variable sample sizes (VSS) detects process shifts faster than the traditional X̄ chart. This article extends these studies for ...

VSSI X̄ charts with sampling at fixed times
(1998-12-01)
A standard X̄ chart for controlling the process mean takes samples of size n0 at specified, equally-spaced, fixed-time points. This article proposes a modification of the standard X chart that allows one to take additional ...

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 ...
