摘要:To capture the experience of skilled operators in response to alarm notifications, a systematic method of process discovery for operator actions in response to univariate alarms is proposed. The contributions of the paper are two folds. First, the transitions of alarm states are defined and formulated as a Petri net model. Second, the methods of process discovery through Alarm & Event logs are presented, where the logs are segmented and reorganized in a format suitable for processing by process discovery algorithms. Finally, the effectiveness and practicality of the proposed methods are illustrated using an industrial case study.
