复杂系统及其仿真研究——为庆祝中国计算机用户协会仿真应用分会成立25周年而作

Complex System and Its Simulation Study

连续系统仿真、离散事件系统仿真、连续-离散混合系统仿真,其应用科学业已相当成熟。不过,它们仅属于简单系统仿真,而简单系统只是复杂系统的特例。复杂系统是客观存在的,它是具有复杂性的系统。复杂系统的理论是一般性的科学,其内容包括现代系统论、非线性科学和复杂性科学。现代系统论的理论体系包含一般系统论、控制论、信息论、耗散结构论、超循环理论、协同学、突变论;非线性科学的理论体系包含混沌、分形、孤立子、模式形成;复杂性科学的理论体系包含神经网络、Agent、进化计算、L-系统、元胞自动机。复杂系统仿真正在逐步掀起复杂系统的面纱,不断推动复杂系统理论向前发展。至于现代系统论,不难找到专著。这里只是着重阐述复杂性科学和非线性科学的仿真研究。

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, hypercycie 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.
