Ch. 12: Inventory Management Practice problems on EOQ Problem 1 A company makes bicycles. It produces 450 bicycles a month. It buys the tires for bicycles from a supplier at a cost of \$20 per tire. The company’s inventory carrying cost is estimated to be 15% of cost and the ordering is \$50 per order. a. Calculate the EOQ In this problem: D = annual demand = (2 tires per bicycle) x (450 bicycles per month) x (12 months in a year) = 10,800 tires S = ordering cost = \$50 per order H = carrying cost = (15%) x (\$20 per unit) = \$ 3.00 per unit per year EOQ = Square root of { (2 x 10,800 x \$50) / \$3 = Square root of 400,000 = 600 tires The company should order about 600 tires each time it places an order. b. What is the number of orders per year? Number of orders per year = D / Q = 10,800 / 600 = 18 orders per year c. Compute the average annual ordering cost. Average annual ordering cost = (18 orders per year) x (\$50 per order) = \$900 per year d. Compute the average inventory. Average inventory = Q / 2 = 600 / 2 = 300 tires e. What is the average annual carrying cost? Average annual carrying cost = (average inventory) x (H) = (300 tires) x ( \$3) = \$900 per year f. Compute the total cost. Total cost = (Average annual ordering cost) + (average annual carrying) = (\$900) + (\$900) = \$1,800
