Study of Agent Model by Combining Logic and Economics Approach

Agent model is the foundation for studying of multi-agent system. The reasons of disjunction between agent model and realization are analyzed. According to the requirements of individual autonomy and social interaction ability of agent, the mechanism of how to constitute the rational agent and society was studied by combining logical and economics approach on the premise of autonomy. An intuitionistic description was introduced on the relation among mental states of agent, including belief desire, utility, convention and intention. It clarifies the decision process of agent rational action. The model is formalized in a quantified multi-modal logic. It perfects the BDI model of Cohen & Levesque and more exactly reflects the rational action of agent and provide a theory foundation for the design and realization of multi-agent system.
