| Abstract: | Standard Shewhart control charts employ fixed sample sizes at equal sampling intervals. By varying the sample size depending on the current location of the process mean, the mean time to detect an off-target condition can be reduced. The adaptive sample size control chart is compared with the fixed sample size control chart in terms of average run length (ARL) under shifts in the process mean of variable magnitude. |
