According to the modeling requirements of electro-optical information systems in joint operations, agent modeling technology is researched, and the agent-based model of the electro-optical information system is built. At first, the composition and function flow of the agent-based electro-optical information system are analyzed. And then, a modeling method based on function modeling and driven by rule data is proposed, and the general framework of the model is given, and the design method of the engagement rule base is discussed. At last, the modeling process of the agent-based electro-optical information system is described from two aspects of model structure design and attributes behavior modeling, and the attribute model and behavior model are established by the object-oriented method. The electro-optical information system modeling based on agent is realized.
