Design and Optimization Aids for Composite Control Charts

ABSTRACT

A free beta computer program is demonstrated for simulation and design of composite control charts that have overall performance specifications. Composite control charts that can be designed by the software include those based on moving average, exponentially weighted moving average, and cumulative sum control charts. the software package, algorithms contained within the software, and an example of using the software to design a four-component composite cumulative sum control chart are described.

KEYWORDS:

• average difference relative to the average
• composite cumulative sum control charts
