Abstract: L'invention a trait à un nouveau système de développement de modèles informatiques dynamiques (évolutifs) en temps réel et aux systèmes informatisés de gestion conçus à l'aide de celui-ci. Le système permet une construction participative de ces modèles, par tous les intervenants autorisés, ainsi qu'un usage partagé, entre tous les usagers autorisés, de chacun des objets (informations, processus, état, seuil, contextes, etc.) constituant ces modèles. Le système permet de représenter et de gérer un système de gestion de l'information. De plus, il permet une représentation «naturelle» (ou intuitive) du système. Tous les types d'information propres à la gestion de tout environnement peuvent donc être modélisés sous forme d'objets représentatifs et être intégrés au système. Il trouvera donc sa niche autant pour la gestion de l'information nécessaire à la gestion administrative, à la gestion des opérations, à la gestion de systèmes-experts, à la gestion de systèmes d'inventaires qu'à la gestion domotique ou toute autre application générique ou spécialisée.

Abstract: A fault-isolating digital data processing apparatus includes plural functional units (12-18) that are interconnected for point-to-point communications by a plurality of buses (20a-20d). The functional units (12-18) monitor the buses (20a-20d) to which they are attached and signal the other units in the event there are bus communication errors. The functional units (12-18) can simultaneously enter into an error isolation phase, e.g., in response to a bus error signalled by one of the units. In addition to signalling bus errors, the functional units can signal unit-level (or "board") faults when they detect fault in their own operation. Each unit (12 or 14) includes error isolation functionality that signals a fault based on (i) whether that unit (12 or 14) signalled a loopback error with respect to its own operation; (ii) whether that unit or another unit signalled a bus error during the error isolation phase; and/or (iii) whether any other functional unit signalled that it was faulty during the error isolation phase.
