Exponentially weighted moving average—Moving average charts for monitoring the process mean
Exponentially weighted moving average—Moving average charts for monitoring the process mean
This research aimed to propose a newly-mixed control chart called the Exponentially Weighted Moving Average—Moving Average Chart (EWMA-MA) to detect the mean change in a process underlying symmetric and asymmetric distributions. The performance of the proposed control chart are compared with Shewhart, MA, EWMA, MA-EWMA and EWMA-MA control charts by …
