系统的核与核度(Ⅰ)

ON SYSTEM CORE AND CORITIVITY(Ⅰ)

一、引言目前研究系统已有不少的方法,如对大系统采用诸如分解与协调、分散、递阶控制等方法;对系统分析采用诸如解析模型法、认识图法、系统动力学方法等.随着社会及科学技术的不断发展,这些方法很难满足许多复杂系统的要求,特别,钱学森等人提出“巨系统”概念,更使人们感到创造研究系统的新方法是当务之急.基于此,本文提出了系统的核与核度的概念.这些概念不但揭示了系统自身固有的特性,而且给出了一种新的研究系统的方法和途径,为对复杂系统的研究提供了一种新的思想.我们已把本文的结果应用于研究巨系统、信息交流网络系统等.

The system analytical method is one of the centre of studying and developing in modernscience.By analysing many natural and social phenomena,a new method of studying system,called “system core and coritivity”,is presented in this paper.Moreover,the maximum andminimum networks structure is obtained when coritivity and the number of mainfactors of sys-tem are given.Finally,we give the methods of constructing the maximum and minimum net-works structure are also presented.
