The EPQ model can be used to maximize inventory management processes and minimize production impact on the environment when adopting cleaner production techniques. In this research an unreliable production process involving rework can be significantly impacted by the machine acclimatization period in an uncertain environment. The machine might need to be modified and maintained for the duration of the acclimatization period in order to function at its best. During the initial phases of production, this may lead to an increase in downtime and a decrease in production efficiency. The machine may not be working at its best during the machine acclimatization period, which can increase the likelihood of flaws and mistakes during the early stages of production. This acclimatization period decreases waste while enhancing machine performance, which leads to a decrease in damaged objects and transforming the process to be more eco-friendly. The aim of this research is to determine the optimal production quantity for minimizing overall costs. We transformed the model's imprecise cost parameters into Triangular Intuitionistic Fuzzy numbers as a way to address their uncertainty. The effectiveness of the model has been verified through numerical solutions.
