Simulation Study for Parametric EWMA and NPWEWPA-SR Control Charts Against Non-Normality Assumptions [PDF]
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.

A Comparative Study of the EWMA and Double EWMA Control Schemes
Abstract A control scheme is the most excellent and irreplaceable tool in Statistical Process Control because of its effectiveness in controlling and monitoring the process, which indirectly helps ensure that the quality of a product is controlled.
