Variable sample size based EWMA control chart with an exponential scaling mechanism for production process monitoring

Variable sample size based EWMA control chart with an exponential scaling mechanism for production process monitoring

Abstract Statistical Process Control is essential for ensuring process stability and detecting variations in a production environment. This study introduces a control chart based on the Exponentially Weighted Moving Average (EWMA) that uses an adaptive sample size. The proposed approach enhances shi...
