Non-Uniform Evaluation Method for Network Security Based on DEA Model
Tao Yue · Journal of Jilin University · 2008
Because traditional evaluation models and methods on network security such as AHP(Analytic Hierarchy Process),fuzzy comprehensive assessment,grey systems methods,need weights determining in advance,and the evaluation results have to deal do with the weights selection especially involving subjective judgment on feelings,ideas and emotions.DEA(Data Envelopment Analysis) was introduced into network security evaluation which determines the weights and priority by solving the mathematical programining corresponding to each alternative network which is called DMU(Decision Making Unit) in DEA.The weights differ from one DMU to another and DEA is a variable weights and non-uniform method.Because the weights are determined in such a way that they should be most favorable to the DMU concerned,the obtained priority relations among alternative networks are relatively optimal and fair without subjectivity.The practical example shows the availability of the established model and method.
