Petri - net based approach to configure online fault diagnosis systems for batch processes / Yi-Chung Chen in Industrial & engineering chemistry research, Vol. 49 N° 9 (Mai 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 9 (Mai 2010) . - pp. 4249–4268 Titre : Petri - net based approach to configure online fault diagnosis systems for batch processes Type de document : texte imprimé Auteurs : Yi-Chung Chen, Auteur ; Ming-Li Yeh, Auteur ; Chia-Lun Hong, Auteur Année de publication : 2010 Article en page(s) : pp. 4249–4268 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Batch  Processes Résumé : Online fault diagnosis is a task of critical importance for maintaining a high level of operational safety in many chemical plants. The Petri-net models are adopted in this work for describing the fault propagation behaviors in batch processes. A systematic method has been developed to synthesize a timed Petri-net hierarchically structured according to any given piping and instrumentation diagram (P&ID) and its operating procedure. On the basis of this model, a diagnoser can be constructed automatically with a computer program for online implementation. Computer algorithms have also been devised to place additional sensors and/or synthesize extra operation steps for the purpose of improving diagnostic performance. Several examples are presented in this paper to demonstrate the effectiveness and correctness of the proposed approach.
