摘要
根据复杂系统脆性的定义,从内因和外因两方面入手,建立一种包含外部环境输入和系统内部组成的复杂系统脆性结构模型。在上层模型中,分析并指出脆性是系统的固有属性,采用脆性熵划分方法,分析复杂系统内部的各种脆性联系。在底层模型中,分析脆性事件对系统的影响,并针对脆性因子,根据最大熵原理建立模型,从模型的最底部直接对系统的脆性风险进行定量分析。
According the definition of complex system's brittleness,considering of the influence of the outside and the inside, we construct the model for analyzing the complex system's brittleness, which includes two levels. On the high level, we (analyze) and point out the brittleness is a basic character of system, and we also analyze all kinds of brittle-(relationship) inside the system. On the low level, we analyze the influence of the vital incident on the system, and construct a model according the maximum entropy principle based by the vital factors.
