It increases with the size of order. VED Analysis means Vital, Essential and Desirable analysis. This also means that such items of inventory enjoy high demand. Therefore this techniques emphasis on classifying the inventory based on its merit and requirement in business operations. vi. The Bailey Seat Firm and General Motors work closely together so that the seats arrive at the assembly plant just as they are needed for each truck being built. Equal order quantity (EOQ) is a feature in material requirements planning systems. Obviously, in order to have smooth production, adequate inventories of these items should be maintained. Total ordering costs are calculated by multiplying the ordering costs per order by number of orders placed during the year. Generally, FIFO leads to higher profits. 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. Economic Order Quantity . A low turnover rate, on the other hand, indicates over-investment and locking up of working capital in undesirable items. As a result, carrying costs continue to incur on such items. Material Management, Inventory Control, Techniques of Inventory Management. To guard against stock-out, the firm may maintain safety stock. 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. 6) FSN Analysis. ABC method is also known as ‘stock control according to value method’, ‘selective value approach’ and ‘proportional parts value approach’. Re-order Point 2. In order to achieve this proper inventory valuation mechanism is required, an inventory valuation facilitates a company to determine a monetary value for items that make up their inventory. Technique # 1. These items are, therefore, needed to be maintained at a minimum level. On the other hand, if goods are purchased in small quantities, carrying costs decrease but ordering costs increase due to increased number of orders. Only if the total cost is lower in the latter case, quantity discount should be availed. The sum of ordering costs and carrying costs represents the total costs of inventory. Danger level is determined by the following formula: Danger level = Average consumption x Maximum reordering point for emergency purchases. Are all the items of inventories equally important, or some of the items are to be given more attention? 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. Slow moving stocks must be evaluated very cautiously before any replenishment orders are placed. Their share in total value of inventory is almost equal to their share in total quantity of inventory. Aging Schedule of Inventory 6. Whenever the inventory level comes down to the re-order point, a fresh order is placed for procuring additional inventory equal to the economic order quantity. A typical quantity discount has the following three effects on the income of a purchaser: (a) A saving in the form of reduced price. The carrying cost is a fixed percentage of the average value of inventory. The optimal level of inventory is popularly referred as EOQ. v. Workers must be multi-skilled in the JIT environment. One of the most important elements in gaining control of inventory is to draft a reports that records information about inventory. Fewer the number of orders lesser the ordering cost. Economic order quantity is that quantity of material for which each order should be placed. 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. The EOQ model assumes that demand remains steady throughout the year and that inventory gets used at a fixed rate. Inventory Control Techniques: EOQ, ABC and others. Suppose the annual usage of an item is 2,000 units, ordering costs are Rs. However, if demand fluctuates, you may run out of inventory sooner than you anticipate. Group B items represent about 25% of items with 20% usage value. Basically the survey aim to discover the level of implementation of inventory management in the automotive service centre. Copyright 10. The category B deserves less attention than A but more attention than C. Items falling in category ‘C’ should be paid minimum attention. While performing this particular analysis, the turnover ratio of each item has to be calculated because the items are sorted and analyzed according to their turnover ratios. If the number of days of two different materials is compared, it is possible to know which is fast-moving and which is slow-moving. The important costs used in this model are the ordering cost, and the cost of carrying (or holding) a unit of inventory in stock. It can be calculated using … By focusing efforts on higher value inventory, a firm can assign proper resources to attain the optimum inventory levels, reduce inventory costs, and ensure that the customers’ needs are fulfilled. Group C consists of about 60—75% of the total items that cost about 5% of the total value. Therefore an effective way of overcoming this problem is maintain balanced stock levels which are described as follows: Signifies minimum level of stock to be maintained regularly, In case stock goes below this level there is danger of stopping the work due to shortage of material. EOQ can be explained with the help of following diagram: ABC analysis is a technique of controlling different items of inventory. Average usage means the quantity of inventory consumed daily. Slow moving items can be identified with the help of inventory turnover ratios. (c) Compute percentage of total usage value for each item. ABC analysis puts emphasis on “where the value is”. Continuing the earlier example, assume that M/s Raghav & Co., uses 300—500 units of auto components per day, and these can be supplied in 3 —5 days, the reorder point is computed as follows –. They should be immediately discarded. Therefore, limitations of the EOQ model are as follows: (a) The EOQ model assumes that demand for a product is spread equally over a period, but in practice there may be seasonal fluctuations in demand for a product. Inventory turnover ratio establishes relationship between average inventory and cost of inventory consumed or sold during the particular period. Stocks of fast moving items must be taken care of constantly and replenishment orders must be forwarded in time to prevent stock-outs. ABC technique saves time and effort in inventory control. interest on capital investment, storekeeping expenses, insurance premium, etc. Economic Order Quantity; A problem which always remains in that how much material may be ordered at a time. Also, if a spare part is, say, an imported component whose procurement lead time is very high, its non-availability may mean a heavy loss. These losses are due to factors like decrease in sales, strained relations with the customers etc. Then there are some materials that may have become obsolete and might not have been demanded for year’s altogether. The situation is depicted in the Fig. The items of group C require minimum level of control. Prohibited Content 3. Inventory Management, also known as stock management, is a crucial part of working capital management. A balance between these two opposing costs – carrying costs and order-processing costs — can be achieved by computing the Economic Order Quantity (Q) with the help of the formula –. The order is forwarded before the amount of raw material depletes to a minimum stock level. TOOLS AND TECHNIQUES OF INVENTORY MANAGEMENT/ CONTROL 16 17. After determining the acceptable cost of inventory, the organization compares the cost with the benefits of the inventory. For example, bearings for a kiln in a cement plant are considered to be vital. AKTUtheintactone 2 Mar 2019 3 Comments. The reorder point can also be explained with the help of Fig. (iii) Just-in-time (JIT) — ordering inventory only as they are needed in the production process. (ii) Carrying Cost – It refers to the cost of keeping items in stock e.g. Signifies the level below the minimum level, when this level of stock is reached the products halts and therefore immediate measures should be taken by the to acquire the stock. The formula to calculate reordering level is as follows: Reordering level = Maximum consumption x Maximum reorder point. The low value and high volume items are included in this category. Group B consists of items which may constitute about 15—20% of the store items and represents about 25—30% of the total value of stores. Various suppliers would then bid for the contract. (iii) Non-moving items that are not being consumed. Technique # 5. The company may need to slash prices on that unsold inventory just to get rid of it. What Would Holding and Ordering Costs Look Like for the Years? If the ordered quantity is large, an order has to be placed less often. Dead stock of inventory signifies money spent that cannot be realized. 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. It is the focal point of many seemingly conflicting interests and considerations, both short-range and long-range. On the basis of objectives of inventory management mentioned earlier, the major problems faced by inventory management are to determine: (a) Level of inventory at which new purchase order should be placed, (b) Quantity of material which should be purchased by each purchase order, and. Report a Violation 11. If those assumptions hold true, you can order at the same time each month or quarter. Re-order Point = 15 days × 2,000 units = 30,000 units. %���� An organization should keep a more rigorous control on items that are costly while less-expensive items should be given less control effort. For instance, General Motors operates using a JIT inventory, relying on its supply chain to deliver the parts it needs to build cars. Quantity based inventory management techniques focuses on determining correct amount of inventory required for business operation with an objective to reduce inventory levels and control inventory operations. Content Filtration 6. Firms that implement the Just-In-Time inventory model may be able to reduce the number of warehouses, they maintain, or even allow them to eliminate those warehouses altogether. These are standard, low-cost and readily available items. The techniques and methods of inventory management may be grouped under:- 1. Safety stock is determined on the basis of comparison between carrying cost of maintaining additional stock and stock-out costs. (a) The usage of a particular item for a given period (usually a year) is known with certainty and the usage rate of the product is even throughout the period. (c) The cost per order of an item is constant and the cost of carrying inventory is also fixed and is given as a percentage of the average value of inventory. S signifies slow moving items whose usage rate is low; therefore, the existing stock of S items lasts for two years or more. (e) The effectiveness of the basic EOQ model is limited by the assumption of a one-product business, and the formula does not allow combining different products in the same order. Another benefit of EOQ is that it is a key to better inventory management and when the company can manage its inventory in an effective way than it can reduce substantial operational costs which in turn will lead to more profits for the company. The EOQ model of determining the optimal order quantity that minimises the total cost of inventory is based on the following assumptions: 1. EOQ calculates the ordering quantity for a particular inventory item using inputs such as carrying cost, ordering cost, and annual usage of that inventory item. Several factors contribute to the criticality of a spare part. Therefore, V items should be stored sufficiently to maintain smooth business operations. The organizations use relaxed inventory procedures for class C items. The organization must have limited suppliers. Effective management of inventory plays a decisive role in deciding a firm’s ability to operate with good profit margins. This is a calculation that helps determine the best amount of inventory to order each time. It is the inventory level at which a new order is placed. The ABC approach states that, when reviewing inventory, a firm should rate items from A to C and exercise control as follows: Group A includes items with highest annual consumption value. These costs vary with inventory size. If the firm is planning a production run, the issue is to decide as to how much production to schedule. This is due to the impossibility of collecting the necessary information for the whole application (including wholesale) and for all products. Every time you place a purchase order, you have to pay the item manufacturer for your goods. The economic order quantity is that size of purchase order, which tends to minimize the total of ordering and carrying, costs. The forecasted consumption for the inventory, usually for one year, is known. However, these costs may vary on account of inflation or due to the change in quantity of the order. In fact, in the inventory control of spare parts and components it is advisable for the organization to use a combination of ABC and VED Analysis.
