Simulation Study for Parametric EWMA and NPWEWPA-SR Control Charts Against Non-Normality Assumptions
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2023 Common control chart types such as EWMA require assumptions to have valid information. The study compares IC robustness and OOC performance for parametric EWMA and NPEWMA-SR control charts in violation of symmetrical assumption.

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.

Design of EWMA-type control chart
IOP Conference Series: Materials Science and Engineering, 2021 Abstract A control chart is typically examined based on the overall performance. This is crucial, as it will influence the final decision on the selection of a control chart. For this reason, the application of average run length (ARL) has been identified as the standard performance metric.
