Abstract: According to the network indicators’ effect, this paper proposes an algorithm integrated with grey correlation degree in grey theory and traditional analytic hierarchy process method to determine the indicators. It considers both objective and subjective factors. Experiments show that this method has a strict mathematical theory basis and a good practical utility. It can improve the evaluation methods’ credibility of network threat assessment.
