Alarm Management Technology and Its Progress in Process Industries

With continuous progress of science and technology, the alarm configurations in process industries have become easier and huger. Due to the complexity of the process system and the unreasonable design of the alarm system, large and invalid alarms have been produced. Operators can be overwhelmed by the large amount of alarms and not take effective measures to abnormal conditions, leading to the occurrence of accidents. In order to effectively manage the alarm system and ensure the safe operation in industrial process, many scholars have made a lot of researches on the related issues of alarm management in process industries. By evaluating the existing methods, the problems in this field and the directions that deserve further research are pointed out in this paper. Finally, prospects are made with respect to the future development of alarm system management. Keywords-alarm management; rational design; multivariate alarm analysis; causal identification
