Abstract We investigate in this paper the effect of measurement errors on the performance of Run Rules control charts monitoring the coefficient of variation (CV) squared. The previous Run Rules - CV in literature is improved slightly by monitoring the CV squared instead of the CV itself. The numerical results show that this improvement gives better performance for Run Rules charts. Moreover, we will show through simulation that the precision and accuracy errors do have negative effect on the performance Run Rules charts. We aslo find out that multiple measurements per item does not high efficiency in reducing these negative effects.
