The nature of this paper reports of an investigation of a set of continuous time ,constant demand inventory models under the condition of yield uncertainty. We consider a classical EPQ model, that models are lot sizing models whose objective is the determination of fuzzy optimal production order and shipment quantity.In this paper, we discuss the inventory problem with fuzzy backorder. Yager’s ranking method for fuzzy numbers is utilized to find the inventory policy in terms of the fuzzy total cost. Finally a numerical example is given to illustrate the model.

The paper proposes the inventory problem with fuzzy backorder
Trapezoidal Fuzzy numbers are described by the ?-cut
Fuzzy optimal order quantity and Fuzzy optimal total cost are derived using Yager’s ranking method
Finally a numerical example is given to illustrate the model.
