| Abstract | ||
| In this research , we use The statistical techniques for detecting shift in quality for production in Babel – factory 2 . By application The exponentially weighted moving average (EWMA) control charts with asymptotic limits , the EWMA control charts with time- varying limits with the fast initial response (FIR-EWMA).this showed that the FIR-EWMA charts are more efficiency for detecting shift in quality | ||
