The novelty of the study is to propose a hybrid IT2 decision-making approach under the hesitant fuzzy linguistic sets for evaluating the criteria and alternatives. For this purpose, the dimensions and criteria are weighted with interval type-2 fuzzy DEMATEL and the economic development plans are ranked by using interval type-2 fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach. Thus, it is possible to evaluate the multicriteria decision-making problem under the hesitancy more accurately by the extended method.
