analysis is the task of finding the root cause of a failure situation in an industrial process. In this paper a new approach for performing alarm analysis using mul-tilevel 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(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.
