where d i represents the relative similarity measure of the ith alternative.
After determining the relative similarity measures of all the alternatives,
they can be ranked, and it is obvious that the bigger the relative similarity
measure, the more superior the alternative.
The framework of the multicriteria intuitionistic fuzzy group decision-
making method for sustainability ranking is shown in Fig. 13.1.

Determine the intuitionistic fuzzy decision-making matrix from
different decision-makers

Determine the weights of the criteria according to the opinions of
different decision-makers

Judgmental Determine the weighted intuitionistic fuzzy decision-making
part matrix determined by each decision-maker

Determine the aggregated decision-making matrix

Determine the ideal and antiideal intuitionistic fuzzy solutions

Determine the degree of the similarity of each alternative and the
ideal intuitionistic fuzzy solution

Analytical Determine the degree of the similarity of each alternative and the
part antiideal intuitionistic fuzzy solution

Determine the relative similarity measure of each alternative and
rank the alternatives
