(54) Title (EN): MODELING OF TRANSACTION FLOW FOR FAULT DETECTION
(54) Title (FR): MODÉLISATION ET SUIVI AUTOMATISÉS DE LA DYNAMIQUE DE FLUX DE TRANSACTIONS AUX FINS DE DÉTECTION D'ANOMALIES DANS DES SYSTÈMES COMPLEXES

(57) Abstract:
(EN): A method and system that automatically derives models (350) between monitored quantities under non-faulty conditions (305) so that subsequent faults can be detected as deviations from the derived models (325). The invention identifies unusual conditions for fault detection and isolation that is absent in rule-based systems.
(FR): La présente invention se rapporte à un procédé et à un système permettant de dériver automatiquement des modèles entre des quantités contrôlées dans des conditions sans anomalies, de manière que les anomalies suivantes puissent être détectées, lesdites anomalies constituant des déviations par rapport aux modèles dérivés. L'invention consiste à identifier des conditions inhabituelles permettant de détecter et d'isoler des anomalies, ce qui est une fonction dont sont dépourvus les systèmes fondés sur des règles.
