A synthetic exponentially weighted moving average control chart to monitor process median based on ranked set sampling [PDF]
ITM Web of Conferences, 2021 Exponentially Weighted Moving Average (EWMA) control charts yield insights into data in a way more comprehensible to the practitioners and researchers because of its capability in discovering small to moderate process mean shifts.

Symmetry of gamma distribution data about the mean after processing with EWMA function
Scientific Reports, 2023 Statistical Process Control (SPC) plays a vital role in maintaining quality and reducing variability in manufacturing processes. Among SPC techniques, the Exponentially Weighted Moving Average (EWMA) stands out for its ability to detect small process ...

Exponentially weighted moving average-Moving average charts for monitoring the process mean.
PLoS ONE, 2020 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.

A STUDY OF THE MEDIAN RUN LENGTH (MRL) PERFORMANCE OF THE EWMA t CHART FOR THE MEAN
South African Journal of Industrial Engineering, 2012 The exponentially weighted moving average (EWMA) chart is effective in detecting small shifts. However, the EWMA chart is not robust enough to prevent errors in estimating the process standard deviation or a changing standard deviation.

An Enhanced Auxiliary Information‐Based EWMA‐t Chart for Monitoring the Process Mean
Applied Sciences, 2020 The exponentially weighted moving average t chart using auxiliary information (AIB-EWMA-t chart) is an effective approach for monitoring small process mean shifts when the process standard deviation is unstable or poorly estimated. To further enhance the
