In this paper, an inventory model with quantity discount has been considered in which demand and purchasing price are taken in terms of triangular and trapezoidal intuitionistic fuzzy numbers. We have used Signed distance method and Graded mean integration representation for defuzzification. Our aim is to obtain the intuitionistic fuzzy optimal order quantity and intuitionistic fuzzy optimal total cost. We have compared the two defuzzification techniques. Numerical analysis is carried out.
