A New Bivariate Control Chart to Monitor the Multivariate Process Mean and Variance Simultaneously

Pages 109-118 | Published online: 15 Feb 2007
 

Abstract

In this article a new control chart which enables a simultaneous monitoring of both the process mean and process variance of a multivariate data will be proposed. A thorough discussion in identifying whether the process mean or variability shifts is also given. Simulation studies will be performed to study the performance of the new chart by means of its average run length (ARL) profiles. Numerous examples are also given to show how the new chart is put to work in real situations.
