摘要
系统有序性是维系系统基本特征,保证系统生存和发展的关键,是衡量系统内在质量的重要指标.文章首先介绍了信息熵的基本概念,论述了它与有序性之间的关系.然后,从物理学、信息论、自组织理论以及耗散结构等多个方面对系统有序进行了分析.进而,论述了系统有序性的几种测度方法,比如概率测度、微观态测度、时效质量测度等.在系统分析中,必须结合实际的系统情形,综合考虑各种系统要素对系统有序性的影响.
System order is the key factor to keep the system＇s basic characters, to drive the system＇s development, and to measure the inner quality of system. The paper introduces the basic concept of information entropy and discusses the relationship between entropy and system order. The system order is analyzed from the view of physics, information theory, self organization theory and dissipation theory. Then some measurement of system order are mensioncd, such as probability, microstates, time-effect and quality etc. When a system is analyzed, the specialities of the system must be considered synthetically.
