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.

Jim's Job Shop buys two parts (Tegdiws and Widgets) for use in its production system from two different suppliers. The parts are needed throughout the entire 52-week year. Tegdiws are used at a relatively constant rate and are ordered whenever the remaining quantity drops to the reorder level. Widgets are ordered from a supplier who stops by every three weeks. Data for both products are as follows: a. What is the inventory control system for Tegdiws? Reorder quantity = 1,225 Reorder point = 824.24 b. Find the total inventory costs if using inventory policy. This is a case considering safety stock (Do not use Excel, show your work) Holding cost per unit per year is given as a percentage of item cost ITEM TEGDIW WIDGET Annual Demand 10,000 5,000 Holding cost (% of item cost) 20% 20% Set up or order cost $150.00 $25.00 Lead Time 4 weeks 1 week Safety stock 55 units 5 units Item cost $10.00 $2.00
