Abstract In order to monitor the ratio of population means of a bivariate normal distribution, Tran et al. [12] have recently suggested a procedure based on Runs Rules, called RRRZ control charts, and showed how their proposed approach efficiently detects small or moderate process shifts. The goal of this paper is to investigate the RRRZ control charts with the 4-out-of-5 Runs Rules by using a Markov chain methodology. We will also compare the performance of these rules using their Expected Average Run Length.
