Abstract. This paper is based on the tutorial given as part of the tutorial programme of CLIMA-VI. The tutorial aimed at giving an overview of the various features available in Jason, a multi-agent systems development platform that is based on an interpreter for an extended version of AgentSpeak. The BDI architecture is the best known and most studied architecture for cognitive agents, and AgentSpeak is an elegant, logic-based programming language inspired by the BDI architecture.

International audienceA Multiagent System (MAS) that explicitly represents its organization normally focuses either on the functioning or the structure of this organization. However, addressing both aspects is a prolific approach when one wants to design or describe a MAS organization. The problem is to define these aspects in such a way that they can be both assembled in a single coherent specification. The ℳOISE + model -- described here through a soccer team example -- intends to be a step in this direction since the organization is seen under three points of view: structural, functional, and deontic

Multi-Agent Systems (MAS) has evolved towards the specification of global constraints that heterogeneous and autonomous agents are supposed to follow when concerning open systems. A subset of these constraints is known as the MAS organisation. This article describes a set of computational tools that supports the development and the programming of such systems. At the system level, it is provided a middleware which ensures that all agents will follow the organisational constraints. At the agent level, the AgentSpeak language is extended, using Jason features, so that the agents can perceive and act upon the organisation they belong.
