A Systematized Approach to Human Properties in Complex Systems

The study of human properties in complex systems is a central problem in the development of 'Complex system theory'. Due to the complexity of this problem, there has been no a general theory to deal with it. In this paper, we develop a general framework to link all the complicated human properties in complex systems. The basic idea of this approach is as follow, first, human properties in complex systems are classified according to the three-level theory of human behaviors then, the detailed theories for each level behaviors are developed finally, human properties in complex systems are studied by these detailed theories. In the first part of this paper, the three-level theory of human behaviors is reviewed briefly. Then human properties In a concrete complex system -- C system -- are analysed very briefly. In the second part, a new theory - an Information model for human activities in complex systems -- is developed in some details which can be used to study the rate-based and knowledge-based behaviors of human beings In complex systems. Finally, a practical system -- the Combat Planning Division In Tactical Air Control Center -- is represented in the framework of this information model.
