Consequence analysis theory for alarm analysis

摘要

Alarm analysis is the task of finding the root cause of a failure situation in an industrial process. In this article, a new approach for performing alarm analysis using multilevel flow models (MFM) is introduced. This approach is compared with existing methods for alarm analysis using MFM. The result of the alarm analysis presented in this article is a set of explanations that fits the observed state of the process. Furthermore, it is shown that the old alarm analysis algorithms are a special case of the method presented here.
