On the performance of coefficient of variation charts in the presence of measurement errors [PDF]
Quality and Reliability Engineering International, 2018 AbstractIn the literature, coefficient of variation control charts have been introduced under the assumption of no measurement errors. However, measurement errors always exist in practice, and they do affect the performance of control charts in the detection of an out‐of‐control situation.
