一般系统的脆性研究

基于一般系统结构理论 ,发展了金鸿章教授等提出的脆性定义 ,并且证明了脆性是一般系统都具有的共同属性。通过对脆性、脆性发生和脆性演化熵等基本概念的定义 ,以及对一般系统结构模型的数学分析 ,结果表明 ,一般系统脆性具有潜在性、连锁性和延时性等特点 ,影响系统脆性发生的主要因素包括随机因素对系统的扰动强度、子系统间的结合强度及其分布。此外 ,结果还表明如果系统的脆性演化熵S≠ 0 ,系统演化成新系统时具有不确定性。

Brittleness of the General Systems

Based on the structural theory of general systems, this paper revises the defini tion of brittleness presented by Pro. Jing Honghzhang, and proves that bittlenes s is the common property of all general systems. Accrording to the mathematical analysis of the structural model of general systems, it is pointed out that the main factors that result in brittleness occurring of general systems include the disturbed intensities of random factors on the systems, interconnection intensi ties of the systems and their distributions. In adeition, the results show that if brittleness evolutional entropy of the systems is not zero, the evolutional r esults become uncertain.
