Abstract: Considering the complex uncertainty of the existing evaluation environment, the trust behavior characteristics among evaluation experts and the consensus of group experts, a group comprehensive evaluation method based on interval Fermatean fuzzy trust network is proposed. Firstly, aiming at the integration of interval Fermatean fuzzy evaluation information, the operation rules of interval Fermatean fuzzy information are proposed, and on the basis of which, an interval Fermatean fuzzy Frank integration method is proposed. Secondly, considering the influence of the trust relationship between evaluation experts on expert weights and consensus, a trust network based on language terms is constructed to calculate expert weights. At the same time, a personalized feedback mechanism is designed, and then a trust consensus interaction model is constructed to improve the group consensus. In addition, for the case of unknown evaluation index weight, an interval Fermatean fuzzy entropy weight method is proposed to obtain the index weight. Finally, the feasibility and superiority of the proposed method are verified by the evaluation of the statistical design ability of business undergraduates in universities.
