| Abstract: | In order to improve the monitoring speed of EWMA standard deviation control chart, an EW- MA control chart with variable sampling sizes and sampling intervals is proposed, in addition, mskes comparison with the traditional and variable sampling interval＇s control chart. It turns out that the moni- toring speed of VSSI EWMA standard deviation control chart is much faster in detecting small shifts through simulation. |
