基于改进云模型的网络信息系统可生存性预测

A prediction algorithm based on improved cloud model for survivability of network information system

网络信息系统的可生存性预测研究对提高网络服务质量有重要作用.针对可生存性评价指标和评价数据的不确定性,提出一种基于改进云模型重心评判法的定性规则提取方法,利用提取的规则构造一个多层次可生存性预测规则推理器,对网络信息系统的可生存性进行不确定性推理.实验结果表明,所提出的新方法具有较好的可用性.

How to predict survivability of network information system is significant for improving net- work service quality. Based on cloud gravity center and rules extraction method of qualitative, a multi -leveland efficient algorithm for predicting survivability is proposed in this paper. Experimental results demonstrate that the algorithm proposed is rather efficient for predicting survivability in network information system.
