A multi item EOQ model for deteriorating items is developed in fuzzy environment. Inventory costs, profit, deteriorating rate and investment constraints are considered to be vague and imprecise in nature. The vagueness of holding cost and set up cost is represented by Hyperbolic Inverse membership function and other fuzzy parameters are represented by linear membership function. The model has been solved by fuzzy non linear programming method. Results have been presented along with crisp model.
