A New Evaluation Method Based on Variable Range of Triangular Fuzzy Number
There is a certain extent of the fuzzy measure with the value of samples and standards in evaluation. Based on the theories of the triangular fuzzy number (TFN) and the variable range fuzzy set, the model for fuzzy approaching degree of triangular fuzzy numbers is established. Then a new evaluation method based on variable range of triangular fuzzy number is proposed in this paper. After analysis of examples, it is shown that this method can further enhance the credibility of the evaluation.
