系统的层次灰类物元综合评判方法

Hierarchical Synthesis System-Evaluation Method Based on Gray Matter-element

为了对信息系统安全等级评估,以物元分析的物元为系统观点,以灰色系统的综合评判为系统方法,提出物元评判算子ME和灰类物元综合评判算子GME,并以此改造层次分析法AHP成为层次化灰类物元综合评判GMHE方法,该方法将人为定性评估与数学定量计算有机结合,不仅可以有效解决大型复杂系统的分类评判,而且还能给出评判结果的可信程度.

To evaluate the rank of security for information system, dealt with the systematic view of matter-element and the systematic method of gray synthesis decision, the operator of ME（Matter-element Evaluation） and the operator of GME （Grey Matter-element Evaluation） were proposed, and by means of those, the hierarchical systematical synthesis-evaluation mehtod based on the gray matter-element was reformed from AHP （Analysis Hierarchy Process）. The method is combined the subjective qualitative appreciaton with the mathematical quantitative measurement. That is the effective classification method for the macro complex system and resulted in the degree of confidence for the systematical evaluation.
