Evaluation of control charts under linear trend

Laura A. Aerne, Charles W. Champ, Steven E. Rigdon

Abstract

The performance of several control charting schemes is studied when the process mean changes as a linear trend. The control charts considered include the Shewhart chart, the Shewhart chart supplemented with runs rules, the cumulative sum (CUSUM) chart, the exponentially weighted moving average (EWMA) chart, and a generalized control chart.
