Enhancing The Performance Of A Short Run Multivariate Control Chart For The Process Mean

Abstract

Short run production is becoming more important in manufacturing industries as a result of increased emphasis on just-in-time (JIT) techniques, job shop settings and synchronous manufacturing. Short run production or more commonly short run is characterized by an environment where the run of a process is short. To meet these new challenges and requirements, numerous univariate and multivariate control charts for short run have been proposed. In this article, an approach of improving the performance of a short run multivariate chart for individual measurements will be proposed. The new chart is based on a robust estimator of process dispersion.
