Operational score graphs provide a real-time indication of a controller's performance
Monitoring a large number of multivariable controllers (MVCs) to ensure that they are being properly operated to maximize benefits has been made easier by developing pattern recognition displays. These displays aid operators and engineers in reducing the time required to recognize improperly set controller limits that might negatively impact plant profitability.
The hydrocarbon and chemical processing industry has expended significant resources over the past several decades on advanced process control (APC) to improve plant profitability. Once APC is commissioned, a sustained performance program must be in place to continue to achieve benefits. One major aspect of sustained performance
