A new protocol to share critical resources by self-organized coordination

International audienceIn this paper we propose a new approach to share critical resources through self-organized coordination. Our approach addresses two levels : first, it allows the expression of agents needs in terms of resources occupancy (getting/leaving a resource) with respect to agents objectives; second, it allows to find a global resources exchange scheme between agents, fitting the agent needs thanks to a negotiation process. Negotiation between agents is held in a decentralized way and allows to produce complex contracts. The underlying protocol is applied to schedule manufacturing tasks on a set of critical machines
