Abstractions booléennes pour la vérification des systèmes temps-réel / Tools supported real-time system verification with combination of abstraction/deduction and Model checkingKang, Eun-Young 08 November 2007 (has links)
Cette thèse présente un schéma formel et efficace pour la vérification de systèmes temps-réel. Ce schéma repose sur la combinaison par abstraction de techniques déductives et de model checking, et cette combinaison permet de contourner les limites de chacune de ces techniques. La méthode utilise le raffinement itératif abstrait (IAR) pour le calcul d'abstractions finies. Etant donné un système de transitions et un ensemble fini de prédicats, la méthode détermine une abstraction booléenne dont les états correspondent à des ensembles de prédicats. La correction de l'abstraction par rapport au système d'origine est garantie en établissant un ensemble de conditions de vérification, issues de la procédure IAR. Ces conditions sont à démontrer à l'aide d'un prouveur de théorèmes. Les propriétés de sûreté et de vivacité sont ensuite vérifiées par rapport au modèle abstrait. La procédure IAR termine lorsque toutes les conditions sont vérifiées. Dans le cas contraire, une analyse plus fine détermine si le modèle abstrait doit être affiné en considérant davantage de prédicats. Nous identifions une classe de diagrammes de prédicats appelés PDT (predicate diagram for timed system) qui décrivent l'abstraction et qui peuvent être utilisés pour la vérification de systèmes temporisés et paramétrés. / This thesis provides an efficient formal scheme for the tool-supported real-time system verification by combination of abstraction-based deductive and model checking techniques in order to handle the limitations of the applied verification techniques. This method is based on IAR (Iterative Abstract Refinement) to compute finite state abstractions. Given a transition system and a finite set of predicates, this method determines a finite abstraction, where each state of the abstract state space is a true assignment to the abstraction predicates. A theorem prover can be used to verify that the finite abstract model is a correct abstraction of a given system by checking conformance between an abstract and a concrete model by establishing/proving that a set of verification conditions are obtained during the IAR procedure. Then the safety/liveness properties are checked over the abstract model. If the verification condition holds successfully, IAR terminates its procedure. Otherwise more analysis is applied to identify if the abstract model needs to be more precise by adding extra predicates. As abstraction form, we adopt a class of predicate diagrams and define a variant of predicate diagram PDT (Predicate Diagram for Timed systems) that can be used to verify real-time and parameterized systems.

Abstract model theoryFraser, Craig Graham January 1976 (has links)
We define a notion of logic that provides a general framework for the study of extensions of first-order predicate calculus. The concept of partial isomorphism and its relation to infinitary logics are examined. Results on the definability of ordinals establish the setting for our proof of Lindstrom's Theorem: this theorem gives conditions that characterize first-order logic. We then consider the analogues to the general case of the compactness and Lowenheim properties. For a wide class of logics it is shown that interesting connections exist between the analogues of these properties. / Science, Faculty of / Mathematics, Department of / Graduate
