【摘要】 系统动力学模型用结构展现系统行为，因此，系统动力学的重点是发现结构。但是，以一种固定不变的结构表现复杂的社会系统，是很粗糙的。本文讨论系统动力学模型的进化问题，即建立模型的染色体，模型的有性繁殖，以及通过选择获得适应力强的个体，最终达到适应变化着的环境的目的。更多还原

【Abstract】 System dynamics model shows the deed of system with structure and the focal point of system dynamics is to find structures.But showing the complex social system with a constant structure is very rough.In this article we will discuss the evolution of system dynamics model including founding the chromosome of model, sexually breeding of model, and gaining some perfectly competent individualities by choosing, consequently achieving the object which adapts the changing environment.更多还原
