1. A computer-implemented method for monitoring the performance of an advanced process control (APC) system having a plurality of system variables used to control an industrial process, the method comprising:

  • determining a count of performance metrics associated with the industrial process in an alarm state;

    determining, based on the count, whether the APC system is in an alarm state;

    determining a service factor for the APC system, wherein the service factor is determined as a ratio of a number of the system variables then currently being manipulated to control the performance metrics to a total number of the system variables of the industrial process available to be manipulated; and

    correlating the alarm state of the APC system and an alarm state of the service factor in order to generate a recommendation for controlling the industrial process using the APC system.
