Abstract

Dalam kajian ini, kami mencadangkan satu cara untuk mengawal varians proses bagi data yang mengandungi cerapan terpencil. Carta yang sering digunakan dalam kawalan varians proses bagi data tercemar ialah carta RQ . Walau bagaimanapun, carta ini kurang peka terhadap pengesanan cerapan terpencil yang melibatkan varians yang kecil. Untuk mengatasi kelemahan ini, carta EWMASRQ telah dicadangkan. In this study, we suggest an approach for the monitoring of the process variance of the data which contain outliers. The chart which is usually used in the monitoring of the process variance for contaminated data is the RQ chart. However, this chart is less sensitive in the detection of outliers involving small variance. To overcome this sho11coming, the EWMASRQ chart is proposed.
