Abstract

La présente invention a pour objet un dispositif et un procédé d’analyse et de diagnostic d’un système, basés sur l’utilisation d’un modèle du système, avec application notamment dans le domaine des installations industrielles pilotées par des automates de commande logique programmée ou câblée. Le procédé comprend une étape d’initialisation du modèle, et une étape de création d’une liste de variables discordantes dont la valeur dans le système diffère de celle prédite par le modèle. Pour chacune des variables appartenant à la liste de discordance, une liste initiale de variables suspectes, soupçonnées d’avoir généré la valeur discordante, est créée, puis une liste restreinte de variables suspectes est obtenue par filtrage de la liste initiale.
