| One of the statistical tools which used to adjust and monitor the output quality is Control Charts. These Charts illustrate the continuation of the Production Process according to the expected Model and random change between produced units. One of these Charts that has been studied in our research is the Exponential Weighted Moving Average and is symbolized by (EWMA) Thus , the main goal of this research is the comparison between the traditional (EWMA ) and modified (EWMA) Control Charts by using data simulation method based on (ARL) indicator with reference to that is generated by Normal distribution. As real data representing the weights of the products of the Iraqi al – Sabah newspaper used. Finally, we found that the modified EWMA control chart is the best. | ||
