In this paper Fuzzy inventory model is developed with price breaks; a joint economic lot-size model is developed under Fuzzy environment. Optimum order quantity and optimum number of price breaks are obtained through the techniques of Fuzzy mathematics. Cost function of both buyer and seller is represented by Fuzzy membership function, and model is solved for optimum results by reformulating it as Fuzzy linear programming problem. For optimum solution of proposed problem, “LINDO” software is used.


Key words: Fuzzy membership function, trapezoidal numbers, price breaks, defuzzification.
