Research on the English Classroom Teaching Effect Evaluation with Interval-Valued Intuitionistic Fuzzy Grey Relational Analysis Method

The English classroom teaching effect evaluation is looked as the multiattribute group decision-making (MAGDM). Thus, a useful MAGDM algorithm needed to cope with it. Depending on classical GRA process and interval-valued IFSs (IVIFSs), this study builds IVIF-GRA assess effect. First of all, concepts IVIFSs are reviewed. In addition, weights criteria derived through CRITIC method. Afterwards, model extended get final result alternative. Therefore, all alternatives could be ranked optimal one can identified. At last, given numerical example some comparative studies obtained. analysis results show that defined algorithms effective for solving evaluation.
