The Shewhart-Ewma Automatic Control Chart
As the amount of critical process data increases due to automatic data acquisition systems, two problems present themselves. First, it becomes uneconomic to add sufficient staff to monitor all these processes using control charts, and second, the skill level required to observe and interpret the control charts becomes an ongoing issue of assuring accuracy and consistency via expensive training programs. An automated control procedure could conceivably provide a solution to both of these issues.
