【摘要】 系统复杂性的本质是高度一体化的多重特性.基于这一本质提出了简单系统、简单非还原系统、复杂还原系统、复杂非还原系统和复杂初系统等概念.社会经济系统具有多重性和模糊性双重复杂性.这种复杂性的形式化具有建立软系统标准表达机制的重要理论意义,并具有为软系统仿真提供概念理论框架的实际意义.提出了一种集合结构的社会经济系统的形式化描述,使得这种复杂性得以形式化地表达.更多还原

【Abstract】 The multiple feature of high integration is the essence of the complexity of systems. The concepts of simple system, simple nonrestoring system, complex restoring system, complex nonrestoring system and complex direct system are put forward based on the essence.Social economy systems possess both multiple feature and fuzziness, the formalization of which has not only profound theoretical significance for setting up a kind of standard expression mechanism of soft systems, but also practical meaning for providing the simulation of soft systems with a conception theory framework. A formalized description of social economy systems with a set structure is presented to describe the double complexities formalization-ally.更多还原
