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?
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?
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?

1. A service station uses 2500 oil filters during the course of a year, and this usage is constant throughout the year. These oil filters are purchased from a supplier 100 miles away for $15 each, and the lead time is 2 days. The holding cost per oil filter per year is $1.50 (or 10% of the unit cost) and the ordering cost is $18.75. There are 250 working days per year. a) the manager decided to change its inventory control model to a fixed time model, with the same lead time of 2 days and placing orders every 2 weeks, with the suppliers. Average daily demand remains at 10 and the standard deviation is 2.5. Currently there are 700 units of inventory on hand. What size orders should he place with suppliers?

Antique manufactures old-fashioned telephones for use in movie scenes (and other displays). Antique's annual demand for rotary telephones is 33,000 units per year, so it needs just as many receptors to assemble the phones. Receptors are ordered from a supplier, and shipping and handling costs are $15 per order (regardless of how many units are on order). The holding costs are $7/unit/year. If the current company policy calls for orders of 3,000 receptors, what are the total annual inventory costs for the receptors? round your final answer to the nearest whole dollar.
A firm requires 90,000 units (D) over a 120-day production period and is placing 2-orders of equal quantity (O). Inventory is used at a constant daily rate. Ordering and Holding Costs are accounted for at end of the production period. Ordering Costs (OC) are $5,000/order and Holding Costs (HC) are $4.00/unit based on average inventory. The price per unit of inventory is $50 (C"). The firm pays for the inventory 5-days after delivery. The firm's cost of capital is 10% (1). For the inventory system, the SECOND order is delivered at f= and payment for that order is made at f= Total Cost Ordering Costs + Holding Costs + Item Cost Total Cost OCx (D/Q)] + [HC (0/2)] + (C x D) Order Number 1 2 - Delivered At t= ORDERING COSTS HOLDING COSTS 5, 120 60, 65 120, 125 5, 10 0 Order Quantity 45,000 Cost $10,000 Payment Due At t= Ⓒ 5 150 PVF 0.998632 0.960526 PV $9,605
