A re-evaluation of repetitive sampling techniques in statistical process monitoring

Abstract

ABSTRACT In this article, we review the literature on the use of the repetitive sampling technique with quality control charts. We raise some important concerns and questions regarding its application and underlying assumptions. We show that a fixed sample size method that requires on average the same amount of sampling can be designed to have as good or better statistical properties when monitoring with data that are normally distributed. Repetitive sampling methods can be useful, however, when monitoring with count data.
