Abstract: This paper introduces a new simulation architecture based on multi-agents, including agent simulation model, agent-oriented simulation control model and intelligent model. With the agent-oriented technologies of the modeling and simulation, we can mostly share the model and simulation technologies, improve the reusability and interoperation of the model, and fully develop the decision support ability of the computer simulation technology. The agent-oriented simulation model presented in this paper has the fine characteristics for reusability interoperation, and intelligence.
