Mixed EWMA-CUSUM and mixed CUSUM-EWMA modified control charts for monitoring first order autoregressive processes
(
Taylor and Francis Ltd.
, 2017 , Article)
In practice most processes are known to produce autocorrelated observations. Autocorrelation degrades the performance of control charts by producing frequent false alarms when the process is stable or makes the charts ...
Optimization design of the CUSUM and EWMA charts for autocorrelated processes
(
John Wiley and Sons Ltd
, 2017 , Article)
The traditional control charts produce frequent false alarm signals in the presence of autocorrelation. The implementation of the modified chart scheme is a way of handling the problem of autocorrelation in control charts. ...
On Model Selection for Autocorrelated Processes in Statistical Process Control
(
John Wiley and Sons Ltd
, 2017 , Article)
Using traditional control charts to monitor autocorrelated processes is not beneficial, because it will lead us to misleading detections in the processes. One of the methods used to deal with the control charts for ...
