Mixed exponentially weighted moving average-cumulative sum charts for process monitoring
TL;DR: A mixed EWMA–CUSUM control chart for detecting a shift in the process mean is proposed and it is revealed that mixing the two charts makes the proposed scheme even more sensitive to the small shifts inThe process mean than the other schemes designed for detecting small shifts.
Journal ArticleDOI
An EWMA-Type Control Chart for Monitoring the Process Mean Using Auxiliary Information
TL;DR: In this article, the authors proposed an EWMA-type control chart which utilizes a single auxiliary variable to detect small and moderate shifts in the process mean, and used regression estimation technique for the mean to define the control structure of the proposed chart.
Journal ArticleDOI
Mixed CUSUM-EWMA chart for monitoring process dispersion
TL;DR: A new control chart named as mixed CUSUM-EWMA (called MCE) control chart is proposed for the efficient monitoring of process dispersion and is compared with other existing control charts and some of their modifications.
Journal ArticleDOI
Enhancing the performance of EWMA charts
TL;DR: In this paper, two runs rules schemes are proposed to be applied on EWMA control charts and evaluated their performance in terms of the Average Run Length (ARL) for small and moderate shifts.
Journal ArticleDOI
Improving the performance of CUSUM charts
TL;DR: This study proposes two runs rules schemes for the CUSUM charts and reveals that the proposed schemes perform better for small and moderate shifts, whereas they reasonably maintain their efficiency for large shifts as well.
