Identifying redundant alarms by determining coefficients of correlation between alarm categories
Abstract:
Methods, systems, and computer-readable media for identifying potentially redundant alarms based on a statistical correlation calculated between categories of alarms are provided. Each alarm in a compilation of alarm history data is assigned to an alarm category. A coefficient of correlation is computed between each distinct pair of alarm categories that indicates the probability that an alarm assigned to the second category of the pair occurs coincidentally within the alarm history data with an alarm assigned to the first category of the pair, given that an alarm assigned to the first category has occurred. Finally, a list of potentially redundant alarms is created consisting of pairs of alarm categories having a coefficient of correlation equal to or exceeding a threshold value.
