Fuzzy inventory model for deteriorating items with price dependent demand

This article focuses on the implementation of fuzzy set theory in the inventory control of deteriorating items where holding cost and deterioration rate are considered as linearly increasing functions of time. An uncertain cycle time is considered and described by a (symmetric) triangular fuzzy number. Demand rate as a function of selling price is also considered. The optimum results are defuzzified by a signed distance method. All results are illustrated numerically and graphically. This research investigates the effect of uncertainty and also directs one to realize the great importance of uncertainty in managing inventory control activity.
