COMPUTER SYSTEM AND METHOD TO PROCESS ALARM SIGNALS

A computer system 100, computer-implemented method and computer program product is provided for processing alarm activations received from one or more technical systems (200). A particular alarm activation represents a deviation of the technical status of a particular technical system from its normal technical status. The computer system (100) includes a data storage interface (111) configured to record a plurality of received alarm activations in a data storage unit (110) wherein the recorded alarm activations correspond to one or more alarms (A1 to A6). Further, a data processing component (120) is configured to determine, from the recorded alarm activations, a plurality of time intervals (I1, I4, 15) for alarm analysis; and to compute similarity measures between the determined time intervals wherein the similarity measures depend on the occurrence of the recorded alarm activations in the determined time intervals. Thereby, the contribution of a particular alarm activation to the similarity of two time intervals is reduced with an increasing occurrence of the alarm in the determined time intervals. Further, a user interface component (130) is configured to provide one or more pairs (131, 132) of time intervals to an operator (10) of the one or more technical systems (200) wherein the one or more pairs (131, 132) of time intervals include time intervals with similarity measures indicating similar alarm floods in the respective time intervals..
