Consequence analysis theory for alarm analysis

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 explanations that fits the observed state of the process. Furthermore, it is shown that the old algorithms is a special case of the algorithm presented here.
