- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.The materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. She knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. She also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four days. If the order size was 1,000 kilograms of resin, what would be the average inventory level?Annual demand= 360 units Holding cost per year = 1 $ per unit Ordering cost = $ 100 per order Compute EOQ , total cost(holding and ordering cost),no of order per year and expected time (days) between orders(Assuming a 300-day work ) and what would the actual total holding and ordering costs be if the annual demand was actually higher than estimated i.e 500 units instead of 360 units, but the EOQ established above is used. If demand for an item is 3 units per day, and delivery lead time is 15 days, what would be the re-order point?
- Hi Tech Corporation (HTC) expects to order 295,000 memory chips for inventory during the coming year, and it will use this inventory at a constant rate. Fixed ordering costs are $300 per order; the purchase price per chip is $32; and the firm’s inventory carrying costs is equal to 18 percent of the purchase price. EOQ=2309.75. If HTC is able to negotiate a reduction in the fixed ordering costs to $250.00 per order, but HTC decides to carry a safety stock of 28 days of memory chip sales. With the reduced fixed ordering cost and the increased average inventory due to the safety stock carried, what is the additional total inventory costs due to the decision to balance out uncertainty by carrying the specified safety stock?Discount-Mart, a major East Coast retailer, wants todetermine the economic order quantity (see Chapter 12 for EOQformulas) for its halogen lamps.
