An interactive display apparatus and method for a plant operating at a plurality of process parametes from which a current plant status can be calculated, and from which symptoms can be diagnosed which indicate the existence of transient conditions of plant status for which mitigating action must be taken within a time interval, utilize a central computer for storing all appropriate mitigating actions which should be taken upon the occurrence of a symptom. The computer is also programmed with algorithms for selecting and prioritizing mitigating actions that are appropriate. A display is connected to the computer for displaying the list of mitigating actions which are appropriate for a symptom diagnosed by the central computer. Sets of symptom indicators and extreme action indicators are also driven by the computer. Each symptom is represented by a separate card which can be independently illuminated to indicate the existence of that symptom. If the symptom is not corrected by appropriate mitigating action within an implied time interval, an extreme action indicator card is lit from along a plurality of extreme action indicators. This indicates to the plant personnel that now extreme action is needed. The central computer also calculates which extreme actions are needed from a list of stored extreme actions. These too are displayed to the plant operator. To help the plant operator on determining the effects of mitigating actions and the ongoing status of the plant, a separate display connected to the central computer, displays current plant status.

An interactive display apparatus for a plant operating at a plurality of process parameters from which a current plant status can be calculated, and from which symptoms of a transient condition in the plant status requiring at least one mitigating action an implied time interval can be diagnosed, extreme action being necessary beyond the time interval if the mitigating action is unsuccessful in mitigating the transient condition, the apparatus comprising: computer means for receiving signals indicative of the process parameters and for diagnosing a plurality of symptoms of transient conditions in the plant status, said computer means operating to measure the time interval for each mitigating action; a plurality of symptom indicators connected to said computer means, each symptom indicator being activatable by said computer means upon the diagnosis by said computer means of one of the symptoms; and a plurality of extreme action indicators connected to said computer means, each extreme action indicator being activatable by said computer means upon expiration of the time interval for taking a mitigating action.
