Application of the enhanced dynamic causal digraph method on a three-layer board machine

This paper presents an enhanced dynamic causal digraph reasoning method for fault diagnosis and its application to a three-layer board machine. The presented method allows to identify the possible faulty process component for the process type of fault. The application of the proposed method to the three-layer board machine is presented at the end of the paper. The results show that the proposed method is able to locate the origin of the fault on a process component level.
