It is an effective method to use Agent for modeling and simulation in a complex environment. The Repast Simphony development platform lays the foundation for Agent modeling and simulation. In this paper, a simulation model of the Repast Simphony system is developed. Then this paper constructs a new electronic information system based on the principle of a composite adaptive system. The system uses different levels of adaptive agents as the base unit. Then, the behavior and relation of agents at the same level are explained in detail, and the information transmission and mechanism of action between agents at different levels are studied. The experimental results show that the agent-based evaluation method can comprehensively consider the advantages and disadvantages of each factor, and it can evaluate other targets. At the same time, this method has higher accuracy and better adaptability.
