Fuzzy Technique for an Inventory Model with Auto-Correlated Demand

It is commonly observed that the demand rates of many consumer goods are auto correlated and are dependent on the price and inventory amount. It is believed that the distribution of demand is independent from time to time. But in real life the demand of goods is auto-correlated. The effects of dependency and auto- correlated demand are studied under a periodic review model. An adaptive order-up-to policy based on the critical fractile is presented and a solution procedure is given. Finally we solve the model by general fuzzy technique. The results and comparative discussions are illustrated numerically.
