Abstract :
This article studies a new feature of the ACUSUM chart related to the exponential w of the sample mean shift in (xt - ¿0)w. The testing cases reveal that the chart outperforms the earlier ACUSUM chart, works as well as the combined schemes consisting CUSUM and/or X¿ charts, but is easier to design and implement. In addition, a general-purpose optimization algorithm is proposed. It can significantly improve the performance of many CUSUM charts over the entire process shift range.
