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.

International audienceThe social and organisational aspects of agency have led to a good amount of theoretical work in terms of formal models and theories. However, the conception and engineering of proper organisational infrastructures embodying such models and theories are still an open issue. The introduction of normative concerns with requirements of openness and adaptation stresses this issue. The corresponding mechanisms for the current infrastructures appear to be not appropriate for managing distributed and open normative organisations. There is still the need of proper abstractions and tools to facilitate application agents taking part in the monitoring of the organisation on one hand, and in the adaptation and definition of the organisation in which they are situated on the other hand. In this paper we present and discuss ORA4MAS (Organisational Artifacts for Multi-Agent Systems), a proposed approach aiming at these issues. Based on the Agents and Artifacts meta-model ( A&A ), it introduces organisational artifacts as first class entities to instrument the organisation for supporting agents activities within it
