Algro Inc. keeps a wide range of parts and materials on hand for use in its production processes. Management has recently had difficulty managing parts inventory as demand for its finished goods has increased; they frequently run out of some critical parts while having an endless supply of others.

A firm is faced with the attractive situation in which it can obtain immediate delivery of an itemit stocks for retail sale. The firm has therefore not bothered to order the item in any systematicway. Recently, however, profits have been squeezed due to increasing competitive pressures, andthe firm has retained a management consultant to study its inventory management. The consultanthas determined that the various costs associated with making an order for the item stockedare approximately $30 per order. She has also determined that the costs of carrying the item ininventory amount to approximately $20 per unit per year (primarily direct storage costs and foregoneprofit on investment in inventory). Demand for the item is reasonably constant over time and the forecast is for 19,200 units per year. When an order is placed for the item, the entire orderis immediately delivered to the firm by the supplier. The firm operates 6 days a week plus afew Sundays, or approximately 320 days per…

Anglo American Platinum uses ABC analysis as an inventory categorisation method. The current inventory ordering policy is to order 10 000 units of an ‘A’-item inventory when the level falls to 4 500 units. Forecast demand to meet production requirements during the next year is 62 500 units. The cost of placing and processing an order relating to this inventory item is R250, while the cost of holding a unit in store is R50 per unit per year. You anticipate that both costs will be constant during the next year. Orders are received two weeks after being placed with the supplier. Assume a 50-week year and that demand is constant throughout the year. Using a quantitative analysis, appraise the optimality of the current ordering policy of the ‘A’-item inventory (Show all calculations).
The EastCoasters Bicycle Shop stocks bikes; helmets;clothing; a variety of bike parts including chains, gears,tires, wheels; and biking accessories. The shop is in astorefront location on a busy street and it has very limitedstorage space for inventory. It often runs out of items and isunable to serve customers. To help manage its inventorythe shop would like to classify the stock using the ABCsystem. Following is a list of items the shop stocks and theannual demand and unit value for each:Classify the inventory items according to the ABC ap-proach using dollar value of annual demand.

Hayes electronics assumed with certainty that the ordering cost is $450 per order and the inventory carrying cost is $170 per unit per year. However, the inventory model parameters are frequently only estimates that are subject to some degree of uncertainty. Consider four cases of variation in the model parameters as follows: (a) both ordering cost and carrying cost are 10% less that originally estimated, (b) both ordering cost and carrying cost are 10% higher than originally estimated, (c) ordering cost is 10% higher and carrying cost is 10% lower than originally estimated, and (d) ordering cost is 10% lower and carrying cost is 10% higher than originally estimated. Determine the optimal order quantity and total inventory cost for each of the four cases. Prepare a table with values from all four cases and compare the sensitivity of the model solution to changes in parameter values.
