Abstract

The present invention relates to maintenance alert monitoring. In order to improve maintenance alert monitoring, there is provided an alert monitoring apparatus (10). The alert monitoring apparatus (10) comprises an input module (12), a change point analyzer (14), a classifier (16), an evolution analyzer (18), and an output module (20). The input module (12) is configured to receive a plurality of time series data of a maintenance alert from a plurality of electronic devices over a period of time, wherein each time series data represents a sequence of the maintenance alert over time from a respective electronic device. The change point analyzer (14) is configured to determine a sequence of alerting volumes over time based on the plurality of time series data of the maintenance alert, and to apply a change point detection method to the sequence of alerting volumes to divide the period of time into a succession of time segments, and to identify temporal boundaries of the time segments as change points. The classifier (16) is configured to classify each sequence of the maintenance alert within a given time segment of the succession of time segments into one of N classes, based on an occurrence pattern of the maintenance alert, wherein N is equal to or greater than 2. The evolution analyzer (18) is configured to determine a distribution of the classes among the plurality of electronic devices within each time segment, and to determine a change of the distribution of the classes over the succession of time segments. The output module (20) is configured to provide the determined change of the distribution of the classes over time.
