Unwanted merchandise is removed from stock and returned lo Ihe manufacturer Ihrough a predetermined, authorized procedure. A principal goal for many of the methods described above is to determine the minimum possible annual cost of ordering and stocking each item. Two major control values are used: 1) the order quantity, that is, the size and frequency of order: and 2) the reorder point, that is, the minimum stock level at which additional quantities are ordered. The Economic Order Quantity (EOQ) formula is one widely used method of puting the minimum annual cost for ordering and stocking each item. The EOQ putation takes into account the cost of placing an order, the annual sales rate, the unit cost、 and the cost of carrying invenlory. Many books on management practices describe the EOQ model in detail. DEVELOPMENTS IN INVENTORY MANAGEMENT In recenl years, two approaches have had a major inipacl on inventory management: Material Requirements Planning (MRP) and JustInTime (JIT and Kanban). Material requirements planning is basically an information system in which sales arc converted dircctly into loads on the facility by subunit and time period. Materials are scheduled more closely, thereby reducing inventories, and delivery times bee shorter and more predictable. Its primary use is with products posed of many ponents. MRP systems are practical for smaller firms. The puter system is only one part of the total project which is usually longterm, taking one to three years lo develop. Justintime inventory management is an approach which works to eliminate inventories rather than optimize them. The inventory of raw materials and workinprocess falls to that needed in a single day. This is acplished by reducing setup times and lead times so that small lots may be ordered. Suppliers may have to make several deliveries a day or move close to the user plants to support this plan. TIPS FOR BETTER INVENTORY MANAGEMENT At time of delivery. Verify count Make sure you are receiving as many cartons as arc listed on the delivery rcccipt.
