Abstract

Engineering Engineering, Industrial Engineering, Multidisciplinary Operations Research & Management Science Science & Technology Technology
Khan et al. presented the results using the approximation for the control chart using a modified exponentially weighted moving average (EWMA) statistic. In this paper, we will correct the results using Monte Carlosimulation. We will show that modified EWMA is more efficient than traditional EWMA in terms of average run length.
