Power functions of the Shewhart control chart

open access: yesJournal of Physics: Conference Series, 2013
The Shewhart control chart is used to check for a lack of control (a shift in the process). However it is insensitive to small shifts. To increase the sensitivity of the Shewhart control chart, some actions can be taken. These include reducing the width of the control limits, increasing the subgroup size to reduce the variance of the sample mean and ...
