Abstract: An EOQ model for deteriorating items under inflation over a finite time horizon is to be discussed here. This article derived a classical and fuzzy model for the effects of deterioration and inflation without any shortage. Due to uncertainty in parameters, we used a pentagonal fuzzy number and then optimise the total inventory cost. For the defuzzification of fuzzy total cost, we use two different methods namely the signed distance method and the graded mean integration method (GMI). Lastly, we discuss some numerical examples, comparative study along with graphical structures, and how this fuzzy model is more reliable for industries.
