eoq technique of inventory management

Calculate the order size, total orders required during a year, total carrying cost and total ordering cost for the year. However, it should be used with thoughtfulness as the items are categorised on the basis of their value and not on their relative importance. Equal order quantity (EOQ) is a feature in material requirements planning systems. (c) A firm may not be able to immediately meet the requirements of a massive and unexpected order, since it has few or no stocks of finished goods. In view of such a relationship, if the organization wishes to minimize the overall cost of inventory, it needs to consider both the ordering cost and carrying cost. Stocks of fast moving items must be taken care of constantly and replenishment orders must be forwarded in time to prevent stock-outs. The optimal size of inventory is the order size which is placed every time. Re-order Point 2. It is the focal point of many seemingly conflicting interests and considerations, both short-range and long-range. 3. Holding a high amount of inventory for a long duration is not idea for a business because of inventory consumes storage space and further it is subject to risk obsolescence and spoilage. Holding costs may include some elements, the costs of which are stepped up with the increase in quantity; for example, if inventory reaches a level where another member of staff is required to control it, there is a stepped increase in costs. This is due to the impossibility of collecting the necessary information for the whole application (including wholesale) and for all products. Furthermore, we have calculated cost estimates to Better Inventory Management. The organization must have limited suppliers. The suppliers must be bound under long-term agreements and prepared to make repeated deliveries in small lots. The annual consumption of inventory of the firm is known and is constant. The EOQ can be mathematically calculated by using the following formula: Inventory management and control refers to a system, which ensures the supply of required quantity and quality of inventory at the required time. The Economic Order Quantity (EOQ) model provides answers to the two basic questions related to inventory management. In determining re-order point, we have assumed that lead time and average usage rate have been correctly estimated. The order point formula minimizes the investment in its inventory and reordering is planned in such a way as to ensure that the orders arrive at precisely the time the inventory reaches zero. However, this may not be realistic. Therefore, inventory management should identify such items and try to reduce investment in inventory of such items. VED Analysis means Vital, Essential and Desirable analysis. The EOQ model is based on the following assumptions: i. These items should be kept at the minimum possible level. But as the order size increases, the carrying costs also increases. ABC analysis involves a perusal of a range of items such as finished products, items lying in inventory or with customers that have different levels of significance and thus, should be handled or controlled differently. Ordering cost are constant. ABC analysis is a technique of categorizing items and determining how much attention each item should receive. On the other hand, holding low amount of inventory can also be disastrous, because the business runs the risk of losing out on potential sales and potential market share as well. It is possible to compute the Economic Order Quantity algebraically. Along with computer-aided manufacturing, the setup for a new production plant can be accomplished in a matter of minutes in less cost. Refers to the rate of inventory at which the organization places the reorder of raw material. Such control system would be found to be more effective and meaningful. A reorder point is estimated by using the formula: Suppose a company uses 10 units of an item per day (usage rate), and the order lead time is 15 days, a new order must be placed when the inventory level reaches 150 units (reorder point 150 = usage rate 10 x lead time 15) so that the inventory is replenished before a stock out occurs. Helping strike a balance between minimal ordering and carrying costs, while still satisfying demand. At the same time, it prevents unnecessary investment in inventories. Average usage means the quantity of inventory consumed daily. It is one of the oldest classical production scheduling models. For example, gaskets for piping connection. If the danger level arises, then the immediate steps should be taken to replenish the stocks, even if more cost incurs in arranging the materials. 4.

At the EOQ level, the increase in carrying costs is completely offset by the decrease in average ordering costs bringing the total cost to minimum. Safety stock size should be determined based on how crucial the item is in production or to the retail business, the item’s purchase cost, and the degree of uncertainty related to both usage and lead time. The sum of carrying cost curve and the ordering cost curve is represented by the total cost curve and the minimum point of the total cost curve corresponds to the point where the carrying cost curve and the ordering cost curve intersect. v. Workers must be multi-skilled in the JIT environment. The economic order quantity (EOQ) is the order quantity that minimizes total holding and ordering costs for the year. (iv) The usage or consumption is in a steady state and is known with certainty. Carrying Cost include storage costs, handling costs, insurance expenses etc. If this method is applied with care, it ensures a considerable reduction in the storage expenses and it is also helpful in preserving costly items. In case of purchases in large quantities, carrying costs increase but ordering costs decrease. 4) SDE classification. Economic Order Quantity; A problem which always remains in that how much material may be ordered at a time. Implementing the Just-In-Time inventory management model allows a firm to serve its customers faster and more efficiently. A number of exchanges have designed for Business-to-Business (B2B) transactions. Therefore, when a safety stock is maintained, the reorder point is computed as –, Reorder Point = Maximum Usage x Maximum lead time, = Reorder level under certainty + Safety Stock, Safety Stock = Increase in usage x Normal Lead time + Maximum usage x Increase in lead time, Reorder Point = Maximum daily usage x Maximum lead time. Once the stock reaches reorder inventory level the company would place a new order or start a new manufacturing run. (b) Arrange the items in descending order according to the usage value. The determinant of when to order in a continuous inventory system is the reorder point. After determining the acceptable cost of inventory, the organization compares the cost with the benefits of the inventory. 4 0 obj <>>> The Bailey Seat Firm supplies GM with all the seats it needs for the production of its full size trucks.
