An Improved Variable Sample Size And Sampling Interval S Control Chart

The standard deviation chart or S chart is used to monitor the process standard deviation. In this thesis, some of the features of the S chart are altered to increase the chart’s sensitivity towards small and moderate shifts in the process standard deviation. This new chart for monitoring the proces...
