Dynamic control of continuous flow processes

A simple and effective method for control of continuous flow processes is presented using two new charts, the Decreased Adjustment and the Mean Square Error Ratio charts. A simulation study illustrates how these charts perform comparably with, or superior to, the best methods currently in use. Further, they have advantages including simplicity and ease of use, good performance without a priori knowledge of a mathematical model of the process, and the ability to operate with a limited number of process adjustments. These charts are ideally suited for many real applications, especially when a human operator must make the adjustments.
