<![CDATA[Inventory has an important role for the continuity of the trading business. In the trading business, consumer demand for the product is usually random. Consumer demand opportunities are aspects that need to be considered in the process of inventory management. Economic Order Quantity (EOQ) probabilistic model (q,r) is the method used when consumer demand is random and the time between ordering until the product comes (lead time) is not equal to zero. This research aims to apply methods EOQ probabilistic model (q,r) in determining the total cost savings in the inventories of oil products in Maju Jaya Tuban workshop. The oil products analyzed were Top 1 and Yamalube oil products. These results indicate that the method EOQ probabilistic model (q,r) has a total inventory cost less than the policy Maju Jaya Tuban workshop. Total inventory cost savings when the ordering cost (10%) and holding cost (1%) is Rp 4.313,- for Top 1 oil products and Rp 3.086,- for Yamalube oil products.Keywords: Oil Demand, EOQ Probabilistic (q,r), Cost Savings]]>
