Fuzzy Inventory Model without Shortages Using Triangular Fuzzy Numbers and Signed Distance Method

A. M. P. Chandrasiri

Abstract: In this paper, we studied Economic Order Quantity (EOQ) inventory model without shortages. Our goal is to determine optimal order quantity and optimal total cost for the proposed model. We introduced triangular fuzzy numbers for ordering cost and carrying cost. Signed distance method is used for defuzzification. Sensitivity analysis is carried out through the results of the numerical example.
