摘要：AbstractIn order to make the best possible use of machine capacity, the duration of downtimes must be reduced as much as possible. Machine operators, who have to resolve the malfunctions that have led to the downtimes, often have to deal with floods of alarms that can overwhelm them. This overload increases the time for identifying the root cause of a downtime, and ultimately, the duration of downtimes. In this paper, an approach is presented that applies a pattern description to detect alarm floods and, through a suppression mechanism, displays only the origin alarm that is characterizing the alarm sequence and shelves the subsequent alarms. The proposed algorithm differs from others, in that it is independent of the order or timing of the alarms and is triggered only by the occurrence of the origin alarm. To investigate whether the shelving mechanism helps to detect the alarm that needs to be tracked to resolve the fault, user tests were conducted. These trials attempted to determine whether the subjects’ performance increased and whether tracking the false alarm occurred less frequently when flood reduction was enabled.
