A rational model of cooperation negotiation in multi-agent system

Cooperative theory and method between agents are important research domains in multi-agent systems (MAS). It is basic that agents can agree on some deals by negotiation tasks, goals and sets of actions. Up to now, various theoretical models have been introduced into the research to cope with the negotiation between agents. How to improve the social rationality of the negotiation is not only one of the main goals, but also one great challenge for researchers. For instance the process of the negotiation is as concise as possible, the deals as the result of the negotiation between agents are as reasonable as possible. Superior-and-inferior relationship is pervasive in almost social community of the human beings. Inspired by this a new theoretical model of the negotiation is designed in this paper in which agents have their own position in grade system and are able to reason and achieve a set of deals by abiding by their situations and relationship and goal's structure. Following "social" strategies, agents propose, accept or refuse different offers until they reach a "fair" agreement. The negotiation model studied in this paper is useful for MAS application and distributed cooperation problem solving.
