failure situation in an industrial process. In this paper 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 paper is a set of explanations that fits the observed state of the process.(More)
Multilevel flow modeling (MFM) is a modeling method for complex technical systems in which the goals and functions of the system are explicitly described. MFM can be used as a basis for root cause analysis, where primary root causes are separated from consequential faults, in complex fault situations. Model representations for use in diagnostic reasoning(More)
