Title
Run sum chart for monitoring multivariate coefficient of variation.
Abstract
•The downward and upward run sum (RS) charts for monitoring the multivariate coefficient of variation (CV) are proposed.•The downward and upward RS charts monitor decreasing and increasing shifts in the multivariate CV, respectively.•Markov chain procedures to evaluate the proposed chart, in terms of ARL, SDRL and EARL, are presented.•Results show that the proposed chart outperforms the existing multivariate chart for monitoring the CV.•An illustrative example is provided to explain the application of the proposed chart.
