چکیده
Résumé Nous définissons une notion de raffinement pour les modèles AltaRica afin de permettre l’analyse de la sécurité de systèmes décrits à différents niveaux de détails. Nous montrons comment s’assurer automatiquement qu’un modèle raffine un autre à l’aide de l’outil de vérification Mec V. Nous présentons deux résultats théoriques, l’un permet de vérifier le raffinement en se focalisant sur un seul composant du modèle à la fois et l’autre caractérise le type d’exigences de sécurité qui sont préservées par le raffinement. Nous proposons d’utiliser ces résultats théoriques pour faciliter l’analyse la sécurité d’un ensemble de systèmes aéronautiques interconnectés.

Safety assessment of AltaRica models via symbolic model checking
AltaRica is a language used to describe safety critical systems that has become a de-facto European industrial standard for Model-Based Safety Assessment (MBSA). However, even the most mature tool for the support for MBSA of AltaRica models, i.e. Dassault’s OCAS, has several limitations. The most important ones are its inability to perform many analyses exhaustively, severe scalability issues, ...
متن کاملToward a scalable refinement strategy for multilevel graph repartitioning
Dynamic load balancing is a mandatory feature for parallel software whose workload evolves with time, such as solvers implementing adaptive mesh refinement. In such solvers, problem space is most often represented as an unstructured mesh, and graph partitioning is used to distribute data and their associated computations across processes. The purpose of this paper is to study the sequential ver...
متن کاملThe Multidimensional Refinement Indicators Algorithm for Optimal Parameterization
The estimation of distributed parameters in a partial differential equation (PDE) from measures of the solution of the PDE may lead to underdetermination problems. The choice of a parameterization is a frequently used way of adding a priori information by reducing the number of unknowns according to the physics of the problem. The refinement indicators algorithm provides a fruitful adaptive par...
متن کاملSymbolic Model Checking and Safety Assessment of Altarica models
Altarica is a language used to describe critical systems. In this paper we present a novel approach to the analysis of Altarica models, based on a translation into an extended version of NuSMV. This approach opens up the possibility to carry out functional verification and safety assessment with symbolic techniques. An experimental evaluation on a set of industrial case studies demonstrates the...
متن کاملUnderstanding Visual Effects in a Windowed Environment
We describe five demonstration programs for displaying variants of effects reported in the vision literature. The demonstrations use a windowed workstation environment, the X Window System Version 11. The performance of the window system is analyzed in terms of our implementation experience and suggestions are made for future window system architectures based on that experience. The visual effe...
