Some Interval-Valued Intuitionistic Fuzzy Dombi Heronian Mean Operators and their Application for Evaluating the Ecological Value of Forest Ecological Tourism Demonstration Areas.

The following takes the scores of A 3 from the IVIFWDHM operator and the IVIFWDGHM operator as examples to show the variation rules: (1) For the IVIFWDHM operator, Figure 2 shows that when the p value is fixed and the q value changes from 1 to 10, the fluctuation trend of the score is more complex, most of which has a decreasing trend; Figure 3 shows that when the p + q value changes from 2 to 20, the fluctuation range increases first and then decreases, and reaches its maximum when the p + q value equals 11, then the fluctuation range is from 0.0450 to 0.0776 when p + q value equals 11, which is the same as that of the scores about the 100 combinations of A 3 .
