Abstract
Techniques are described for monitoring the performance of advanced process control (APC) systems used to control complex industrial processes. By correlating an alarm status of the APC system with an alarm status associated with the service factor (or service factor thresholds), a plant operator can understand how well the APC system performs over time, as well as identify when operator intervention may be required (or alternatively, may be the source of poor plant performance). Accordingly, embodiments of the invention can significantly impact both the reliability and efficiency of complex industrial process, e.g., the production of industrial gases using air separation units (ASUs) and steam methane reformer (SMR) furnaces.
