Abstract: Abstract The intuitionistic fuzzy set theory extends the notion of fuzzy set theory in a more generalized way, which includes the sense of belongingness (acceptance) as well as nonbelongingness (rejection). A decision-making phenomenon may go through a vague situation with the dilemma of acceptance and rejection. An economic order quantity (EOQ) model having a fixed goal to reduce the costs as much as possible can be a model of imprecise decision-making with an acceptance-rejection dilemma in the manager’s mind. Thus, an EOQ model may be considered in an intuitionistic fuzzy uncertain environment. In a situation where the parameters and decision variables are of the imprecise nature of the intuitionistic fuzzy type, it is better to describe the uncertain model with the help of intuitionistic fuzzy calculus. Thus, this chapter aims to discuss the classical EOQ model in uncertain intuitionistic fuzzy phenomena. The intuitionistic fuzzy differential equation approach is considered to describe the fuzzy model. Here, the demand and costs are taken as triangular intuitionistic fuzzy numbers (TIFNs). Also, a new defuzzification technique is established in this chapter, which is used to compare the results obtained for crisp and intuitionistic fuzzy models. The intuitionistic fuzzy environment with (i)-differentiability of q(t) appears to offer the best result for the cost minimization goal among the three discussed approaches, whereas the intuitionistic fuzzy environment with (ii)-differentiability of q(t)reveals the worst result, according to the numerical analysis.
