Complex System and Its Simulation Study

Application science of continuous system simulation,dispersed event system simulation and continuous-dispersed hybrid system simulation is very ripe at present.But it's just simple system simulation,and simple system is only a special example of complex system.The complex system exists objectively,it's a system with complexity.Complex system theory is general science,its content includes modern system theory,nonlinear science and complexity science.Modern system theory contains general system theory,cybernetics,information theory,theory of dissipative structures,hypercycle throty,synergetics,catastrophe throry.Nonlinear science contains chaos,fractal,soliton,pattern forming.Complexity science contains nervous network,agent,evolution count,L-system,cellular automata.Complex system simulation is promoting the development of complex system theory.As for modern system theory,finding special writings is not difficult.The paper expounds only simulation study of complexity science and nonlinear science.
