چکیده مقاله:
The cumulative sum (CUSUM) control chart is known to be sensitive to slight changes in the process quality characteristics. The design of this control chart is based on a series of cumulative sums of the statistic derived from the data. To monitor both changes of the mean and variance
simultaneously and comprehensively, we propose a combined CUSUM-Shewhart ??? control chart based on a single statistic for normally distributed characteristics. It has been demonstrated that the proposed combined chart detects the out-of-control state with smaller average run length (ARL) as compared to other charts like CUSUM ??? , omnibus EWMA, and the standard ??? control chart
