11) Which of the following is NOT an assumption of the economic order quantity model shown below? Q* = A) Demand is known, constant, and independent. B) Lead time is known and constant. C) Quantity discounts are not possible. D) Production and use can occur simultaneously. E) The only variable costs are setup cost and holding (or carrying) cost. 12) What is the primary purpose of the basic economic order quantity model shown below? Q* = A) to calculate the reorder point, so that replenishments take place at the proper time B) to minimize the sum of carrying cost and holding cost C) to maximize the customer service level D) to minimize the sum of setup cost and holding cost E) to calculate the optimum safety stock 13) If the actual order quantity is the economic order quantity in a problem that meets the assumptions of the economic order quantity model shown below, the average amount of inventory on hand: Q* = A) is smaller than the holding cost per unit. B) is zero. C) is one-half of the economic order quantity. D) is affected by the amount of product cost. E) goes down if the holding cost per unit goes down. 14) A certain type of computer costs $1,000, and the annual holding cost is 25% of the value of the item. Annual demand is 10,000 units, and the order cost is $150 per order. What is the approximate economic order quantity? A) 16 B) 70 C) 110 D) 183 E) 600 15) Most inventory models attempt to minimize: A) the likelihood of a stockout. B) the number of items ordered. C) total inventory-based costs. D) the number of orders placed. E) the safety stock. 16) In the basic EOQ model, if the cost of placing an order doubles, and all other values remain constant, the EOQ will: A) increase by about 41%. B) increase by 100%. C) increase by 200%. D) increase, but more data is needed to say by how much. E) either increase or decrease. 17) In the basic EOQ model, if D = 6000 per year, S = $100, and holding cost = $5 per unit per month, what is the economic order quantity? A) 24 B) 100 C) 141 D) 490 E) 600 18) Which of the following statements about the basic EOQ model is TRUE? A) If the ordering cost were to double, the EOQ would rise. B) If annual demand were to double, the EOQ would increase. C) If the carrying cost were to increase, the EOQ would fall. D) If annual demand were to double, the number of orders per year would increase. E) All of the above statements are true. 19) Which of the following statements about the basic EOQ model is FALSE? A) If the setup cost were to decrease, the EOQ would fall. B) If annual demand were to double, the number of orders per year would increase. C) If the ordering cost were to increase, the EOQ would rise. D) If annual demand were to double, the EOQ would also double. E) All of the above statements are true. 20) A product whose EOQ is 40 units experiences a decrease in ordering cost from $90 per order to $10 per order. The revised EOQ is: A) three times as large. B) one-third as large. C) nine times as large. D) one-ninth as large. E) cannot be determined
