Comparative studies on the effectiveness between X and synthetic control charts

Traditional X Charts used for Statistical process control is quite ineffective in detecting small shifts in mean. In this project, a Synthetic chart has been designed and a comparative study on the effectiveness between X and Synthetic Control Charts is conducted. This is accomplished by analyzing t...

In this project, a Synthetic chart has been designed and a comparative study on the effectiveness between X and Synthetic Control Charts is conducted.
