“…This is done by interpreting the operational semantics of the used formalism on the model with all possible values for parameters and variables that are assigned nondeterministically. Regarding the notion for a transition, possible means that the corresponding guard is met [48,68,71].…”

“…Mashkoor et al 69 presented the notion of fidelity to allow the validation by simulation of Event‐B specifications. The VTA framework has been proposed by Mashkoor and Jacquot 70 to integrate the verification and validation of formal requirements specifications, and three case studies are presented: the land transport domain model, the landing gear system, and the platooning system.…”

A Cyber-Physical System-of-Systems (CPSoS) can be defined as a System-of-Systems (SoS), composed of a number of operable and autonomous Constituent Systems (CSs) that are themselves Cyber-Physical Systems (CPSs). A main challenge in integrating CPSoS to function as a single integrated system is the autonomy of its components, which may result in conflicts due to the lack of coordination among its CPSs. In this paper, we advocate that in order to facilitate the integration of CPSs within the overall context of their CPSoS, we may need to adjust their level of autonomy in a way that enables them to coordinate their activities to avoid any conflict among one another. Reducing such conflicts surely contributes to the dependability of the CPSoS. In particular, we propose a novel modelbased approach for modeling and analyzing the autonomy levels of CPSs based on their awareness concerning their operational environment as well as their capability to react in a timely and safe manner while performing their activity. The model is further described in a UML profile and applied to represent activities for autonomous driving scenarios. Using a driving simulator, we implement such models on a target vehicle and we show the resulting safety improvement, especially in terms of reduced collisions.

“…Les outils d'aide à la validation de modèles Event-B (Mashkoor et al, 2016a), (Mashkoor et al, 2016b), (Jacquot, 2015) ont mis en évidence la possibilité de définir des sémantiques mathématiques qui garantissent la correction de modèles exécutables. Ils ont esquissé une extension de la notion de raffinement en tant qu'étape dans le processus de développement.…”

L'amélioration de la qualité d'un système commence par l'expression de ses besoins en langage naturel. Notre objectif est de prendre en compte la validation dès la compréhension des exigences et tout au long du développement de la spécification en Event-B. Pour combler l'écart entre le cahier des charges et sa spécification formelle, nous explicitons les interactions entre ces deux mondes. La validation est étudiée pour les modèles formels relativement aux exigences. La vérification permet de détecter des incohérences et des contradictions dans le cahier des charges et dans la spécification Event-B. La place des outils disponibles, notamment avec la plateforme Rodin, est importante tout au long du développement, améliorant sa qualité et sa documentation. Rodin et le plug-in ProR permettent de gérer la trace des besoins en lien avec la spécification en cours de construction. L'ensemble des documents disponibles et les retours des outils de validation et vérification sont disponibles tout au long du développement. Notre approche est illustrée par l'étude de cas d'un système de contrôle du train d'atterrissage d'un avion. ABSTRACT. Improving the quality of a system begins by the requirements elicitation. Our goal is to take into account the validation since the understanding of the requirements and all along the development of their Event-B specification. Our challenge is to bridge the gap between requirements, those of the client, and the specification, that of the computer scientist. We make explicit the interactions between the requirements and the specification under construction. The validation is studied for formal models with regard to the requirements. The verification may detect incoherences and contradictions in both requirements and formal specification. The Rodin platform tools are important all along the development to improve the quality and the documentation of the system. Rodin and the ProR plug-in allow us to manage the trace of the requirements and their specification. The documentation and the feedback of the different used tools for the validation and verification are available at any time of the development. We illustrate our approach to the case study of an aircraft landing system.
