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 $100 per order, and that the lead time for delivery is four days. If the order size was 1,000 kilograms of resin, what would be the average inventory level?
Green Grass Industries Limited (GGIL) has used a fixed-time period inventory system that involved taking a complete inventory count of all items each month. However, increasing labor costs, are forcing GGIL, to examine alternative ways to reduce the amount of labor involved in inventory stockrooms, yet without increasing other costs, such a shortage costs. Table 10 is a random sample of 20 GGIL's items. Table 10. Annual Usage by Value of a sample of GGIL's Inventory Item Number Annual Usage ($) Item Number Annual Usage ($) 1 10,600 11 2,750 2 14,000 12 1,400 3 4,000 13 3,200 4 16,000 14 2,500 5 8,100 15 110,000 1,800 16 14,800 7 84,000 17 9,500 8. 890 18 1,700 9 940 19 3,700 10 94,000 20 12,500 a) What would you recommend GGIL to do to cut back its labor cost? (Illustrate using an ABC plan). b) Item 18 is critical to continued operations at GGIL. i. How would you recommend it be classified? ii. Give the reason(s) for your answer.
Define each of the following terms: c. Economic Ordering Quantity (EOQ); EOQ model; EOQ range
Current decision to buy: Ross White's machine shop uses 200 brackets each month during the course of a year. This usage is relatively constant throughout the year. Currently, these brackets are purchased from a supplier 100 miles away for $16 each and the lead time is 2 days. The holding cost per bracket per year is $1.60 (10% of the unit cost) and the annual ordering cost per order is $18.50. There are 240 working days per year. Possible future decision to make in-house: Ross White is reconsidering his decision of buying the brackets and is considering making the brackets in-house. He has determined the set up costs would be $24.50 in machinist time and lost production time. Forty eight brackets could be produced in a day once the machine has been set up. Ross estimates that the cost (including labor and materials) of producing one bracket would be $14.85. The holding cost would be 10% of the cost. a. What is the EOQ given Ross' current decision to buy the brackets? What is the total…

DETERMINING INVENTORY MODELS FSYHILD is a manufacturing company of made to order face shield. It is producing products at a constant rate with a requirement of 5,500 face shields per quarter throughout the year. If ordering costs are P35.00 per order, unit cost is P10.00 per face shield, and annual inventory holding cost are charged at 30% of the units cost. A. What is the EOQ for this component? B. What is the expected time between orders? C. What are the total annual inventory and holding cost associated with your EOQ recommendation? D. Assuming a lead time of 5 days, what is the reorder point? E. What is the total cost if the management decides to increase the demand by 75%?
