摘　　要：针对复杂系统仿真普遍缺乏层级思想,局限于广度模拟的情况,对复杂适应系统(CAS)层级建模进行研究,协同进化理论,从主体平均适应度的角度,分析中间子系统的生成、过渡和演化,得到层级结构产生的内在动因,提出层级CAS演化的数学模型和层级框架。该模型应用于多人重复囚徒博弈,结果证明其能在高N值时形成稳定高合作率。Aiming at the status of complex system lack of level thought commonly to be limited of extent simulation, this paper researches the multi-level modeling for Complex Adaptive System（CAS）. It combines the theory of co-evolution from the perspective of average fitness of subject, analyzes the generation, transition and evolutionary of middle subsystem, and gets the internal causes of making hierarchical structure. It proposes a mathematical model of level CAS evolution and level framework. The model applies in N-player iterated prisoner＇s dilemma, and the result proves -hat it can emerge a higher and steadier rate of cooperation under high value of N.
