A Network Survivability Evaluation Method Based on PDRR Model
Wu Leitao, Yue Mingqiao, Zhang Hengbo, He Chengbo · 2023
Due to few researches on network survivability evaluation at present, this paper proposed an index system of network survivability evaluation based on the PDRR strategy. In view of the discreteness caused by the strong subjectivity of index assignment, the improved TOPSIS model is introduced for modeling calculation. According to the preset rules, the virtual Marine network survivability evaluation is carried out with the evaluation index quantification method. The calculation results show that the improved TOPSIS method can effectively suppress the discreteness of subjective evaluation by experts, which made the selected index system reasonable and provided a basis for the evaluation of the network's survivability.
