Measuring the performance improvement of a double generally weighted moving average control chart

作者：

Highlights：

• A new control chart SS-DGWMA is proposed to detect the shifts of a process.

• Simulations are performed to evaluate the average run length and standard deviation of run length of these three charts.

• The ARL1s and SDRL1s of the new chart are smaller than those of the other two chart.

• The performance of the new chart is superior to that of the other two charts in all studied scenarios.
