The ability to map the relationship between elements in a system that is characterized by either a cause or effect group is the main advantage of the DEMATEL method. It has been integrated with fuzzy set theories since it can provide more reasonable results in an uncertain environment. However, the computational complexity of the Intuitionistic Fuzzy DEMATEL (IF-DEMATEL) method has become one of the limitations to researchers in previous studies. Thus, the aim of this paper is to investigate the effects of the order of defuzzification in IF-DEMATEL. Three sets of calculations (A, B, and C) are executed to achieve this objective using a hypothetical example. The results show that there is a significant effect of the defuzzification order in IF-DEMATEL.
