Explicit analytical solutions for the average run length of modified EWMA control chart for ARX(p,r) processes [PDF]
Statistical process control (SPC) plays a necessary role in manufacturing industry processes. An essential tool for SPC used for monitoring, measuring, controlling, and improving quality in various fields is the control chart.

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.

Enhancing the performance of EWMA charts [PDF]
Control charts are extensively used in processes and are very helpful in determining the special cause variations so that a timely action may be taken to eliminate them. One of the charting procedures is the Shewhart‐type control charts, which are used mainly to detect large shifts.
