1. A computer-implemented method for determining an operational state of an industrial plant, wherein the industrial plant is configured to execute a given industrial process, the method comprising:
acquiring a plurality of alarms raised within the plant,
adding the plurality of alarms to a pool of important alarms;
determining, based at least in part on a topology of the plant, and/or on the given industrial process, and/or on a physical state of the plant or any part thereof, for at least one first acquired alarm from the plurality of alarms, whether a physical state of the plant or any part thereof indicated by the at least one first acquired alarm has caused a second alarm that has also been acquired, wherein the second alarm represents an escalation of an initial problem indicated by the at least one first acquired alarm that needs fixing more urgently than the initial problem, and when the second alarm is present, moving the at least one first acquired alarm from the pool of important alarms to a pool of informative alarms; and
determining the operational state of the plant, and/or a corrective action for improving this operational state, based on the alarms in the pool of important alarms.
