Design strategies for the multivariate exponentially weighted moving average control chart
The multivariate exponentially weighted moving average (MEWMA) control chart has received significant attention from researchers and practitioners because of its desirable properties. There are several different approaches to the design of MEWMA control charts: statistical design; economic-statistical design; and robust design. In this paper a review and comparison of these design strategies is provided. Copyright © 2004 John Wiley & Sons, Ltd
