Research on modeling and simulation of space information system based on agent

Space information system (SIS) is a typical complex system, which challenges traditional modeling methods. Agent-based modeling and simulation (ABMS) can be an appropriate and effective approach to modeling and simulation of SIS. Firstly, the advantages and basic concepts of ABMS are introduced briefly. Secondly, the complexity of SIS is analyzed, and it is concluded that the complexity of SIS results from the diverse component entities and their relations. Thirdly, the entities involved in SIS are classified as three categories, and on the basis, the structure models of Agents and object are built, including reactive Agent, cognitive Agent and environment object. Finally, an implementation plan of SIS simulation is put forward, and SIS simulation system software with basic functions is developed. And the foundation of further researches on modeling and simulation of SIS is laid.
