Study on Situation Evaluation for Network Survivability Based on Grey Relation Analysis
Guosheng Zhao · Journal of Chinese Computer Systems · 2006
Through evaluating the changes of key services′ performance index value before and after it was assessed, this paper proposed an quantitative evaluation method about network survivability situation based on grey relation analysis. Starting with normalizing interval number performance index decision-making metrics, it applied grey relation analysis to assess the best affiliate degree and survivability probability of every key service. Then it assessed the changes of every key service′s survivability situation based on network entropy difference. Finally, it gained the synthesis evaluation about the whole network system. An instance and simulation are given to show the proposed method can effectively evaluate the actual survivability situation of network system.
