A system and method, which may be implemented in a plant such as a refinery, are provided for identifying at least one mismatch between operation of at least one process unit and a scheduled target for that process unit. Production values are obtained for each process unit of interest, as are prices and scheduled targets for each process unit. A differential profit value is calculated for each process unit or the set of process units, the differential profit value representing a difference in profit based on the scheduled target and the production value for the profit units. The differential profit value can be indicative of the mismatch. Remedial action can then be taken to alter a scheduled constraint of one or more process units, or an operational constraint of one or more process units.
