Evaluation Model Based on Hesitation Fuzzy Theory

Fuzzy mathematics is widely used in the field of multi-attribute decision making and evaluation. The extended form of fuzzy sets, hesitant fuzzy sets, has also received extensive attention in recent years. In this paper, an evaluation model is proposed to justify hesitant fuzzy linguistic term set combines hesitant fuzzy set with hierarchical analysis to construct a comparison matrix and check the matrix consistency. The fuzzy data are fused with the exact data, and then the hesitation fuzzy operator is applied to fuse the data and weights to obtain the final evaluation results. The network attack effect evaluation index system is proposed, and the network attack effect is evaluated by using the evaluation model.
