Modélisation, spécification formelle et vérification de protocoles d'interaction: une approche basée sur les rôles

In this thesis we present a proposal for communication protocol speci cation in the context of multiagent systems, with an approach we call role based. The idea of role is frequently found on the multiagent systems domain, representing very often the functionnality accomplished by the agent within the system, functionality that is usually expressed as message sequences following well de ned protocols. This proposal is based on the notion of role attribute, as it is implied on the agent-oriented methodologies MADKIT and GAIA. Roles could be seen as social attributes of agent groups, that are taken in the context of any given interaction. If we see roles like this, we could also imagine schemes to generate an actual speci cation with concrete agents from the generic speci cation using roles. To test this approch we propose a machine-assisted speci cation process that takes a role de niton expressed on a visual notation (AUML), and generates a formal equivalent on the language Promela.
