Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 N°19 (Octobre 2008) . - p. 7335–7346 Titre : Development of an optimal sensor placement procedure based on fault evolution sequences Type de document : texte imprimé Auteurs : Jung Yang Chen, Auteur ; Chuei-Tin Chang, Auteur Année de publication : 2008 Article en page(s) : p. 7335–7346 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Sensor placement procedures SDG-based strategy Résumé : The diagnostic resolution issues are usually addressed with a quantitative or semiquantitative approach in the reported studies concerning sensor placement procedures. Since the required information for implementing the traditional methods may not be always available, a SDG-based strategy is proposed in this paper to design the sensor networks on the basis of qualitatively predicted fault evolution sequences. To achieve a maximum level of resolution and, at the same time, to ensure observability, the corresponding design problems are formulated as integer programs in this work. Two alternative strategies are also developed for producing the optimal solutions. The feasibility of the proposed method is demonstrated with three examples.
