Circular Intuitionistic Fuzzy TODIM Approach for Material Selection for Cryogenic Storage Tank for Liquid Nitrogen Transportation

In this paper, a circular intuitionistic fuzzy set is implicated, which the extension of and an set. The includes radius for both membership non-membership. After this, we describe TODIM method decision making, can handle quantitative qualitative criteria, as well imprecise uncertain information. takes into account decision-maker’s subjective preferences attitudes towards criteria while also considering uncertainty imprecision in decision-making process. We define algorithm C-IF-TODIM approach decisions making problem. proposed fuzziness circularity problem, come from fact that are depend on each other. A case study choosing materials cryogenic storage tank used to test method, results compared those other ways decisions. show makes more accurate reliable it complexity tanks well. reviewing help make liquid nitrogen transportation safer reliable, will cut down chance accidents financial losses. be applied domains where information common.
