Question 1. 1. (TCO 4) a company has recorded the last 5 days of daily demand on their only product. Those values are 120, 125, 124, 128, and 133. The time from when an order is placed to when it arrives at the company from its vendor is 5 days. Assuming the basic fixed-order quantity inventory model fits this situation and no safety stock is needed, which of the following is the reorder point (R)? @See Chapter 11, page 367. Using equation 11.4, average demand is 120 + 125 + 124 + 128 + 133/5 = 126. Lead time = 5 days so the reorder point is 126 x 5 = 630. (Points : 10) |
120 126 630 950 1,200 |
Question 2. 2. (TCO 4) You would like to use the fixed-time period inventory model to compute the desired order quantity for a company. You know that vendor lead time is 5 days and the number of days between reviews is 7. Which of the following is the standard deviation of demand over the review and lead time if the standard deviation of daily demand is 8? @See Chapter 11, page 374. Using equation 11.12, the standard deviation of demand over the 12 days of time between reviews and lead time is the square root of (12 x 64) = 27.71. (Points : 10) |
About 27.7 About 32.8 About 35.8 About 39.9 About 45.0 |
Question 3. 3. (TCOs 3, 4, and 5) If the average aggregate inventory value is $45,000 and the cost of goods sold is $10,000, which of the following is weeks of supply? @See Chapter 13, page 451. Weeks of supply = (Average Aggregate Inventory/Cost of goods sold) x 52 = (45,000/10,000) x 52 = 4.5 x 52 = 234. Note that Cost of Goods sold is an income statement item and refers to an annual figure. Average Aggregate Inventory is a balance sheet item. (Points : 10) |
45,000 234 120 23.4 4.5 |
Question 4. 4. (TCO 5) If a firm produced a standard item with relatively stable demand, the smoothing constant alpha (reaction rate to differences) used in an exponential smoothing forecasting model would tend to be in which of the following ranges? @See Chapter 3, page 56. If a firm produced a standard item with relatively stable demand, the reaction rate to differences between actual and forecast demand would tend to be small, perhaps just 5 or 10 percentage points.(Points : 10) |
5% to 10% 20% to 50% 20% to 80% 60% to 120% 90% to 100% |
Question 5. 5. (TCO 2) Various financial data for SunPath Manufacturing for 2012 and 2013 follow. What is the percentage change in the multifactor labor and raw materials productivity measure for SunPath between 2012 and 2013? | | 2012 | 2013 | Output: | Sales: | $300,000 | $330,000 | Inputs: | Labor: | $40,000 | $43,000 | | Raw Materials: | $45,000 | $51,000 | | Energy: | $10,000 | $9,000 | | Capital Employed: | $250,000 | $262,000 | | Other | $2,000 | $6,000 |
@SeeChapter 2, page 38. The multifactor labor and raw materials productivity measure for 2012 is $300,000 divided by the sum $40,000 + $45,000 or 3.53. For 2013, it is $330,000 divided by the sum $51,000 + $43,000 or 3.51. The percentage change between 2012 and 2013, then is (3.511 – 3.529)/3.529 or -0.018 divided by 3.529 = -0.53%. (Points : 10) |
-9.22 2.33 -0.53 -2.88 10.39 |
Question 6. 6. (TCO 5) A company wants to forecast demand using the weighted moving average. If the company uses three prior yearly sales values (i.e., year 2011 = 160, year 2012 = 140, and year 2013 = 170), and we want to weight year 2011 at 30%, year 2012 at 30%, and year 2013 at 40%, which of the following is the weighted moving average forecast for year 2014? @See Chapter 3, page 53. Forecast for 2014 = (160×0.3) + (140×0.3) + (170×0.4) = 158. (Points : 10) |
170 168 158 152 146 |
Question 7. 7. (TCO 5) If demand for product “A” were forecast at 1,000,000 units for the coming year and your factory has one machine capable of producing 75,000 units per month, how much of product “A” might you plan to acquire through outsourcing? @See Chapter 4, page 102. The answer is 100,000 units. You can produce 75,000 units times 12 months = 900,000 units. The shortfall is 1,000,000 minus 900,000 or 100,000 units. (Points : 10) |
500 10,000 100,000 200,000 600 |
Question 8. 8. (TCO 3) You have been called in as a consultant to set up a Kanban control system. The first thing to do is to determine the number of Kanban card sets needed. Your research shows that the expected demand during lead time for a particular component is 150 per hour. You estimate the safety stock should be set at 25% of the demand during lead time. The tote trays used as containers can hold eight units of stock and the lead time it takes to replenish an order is 2 hours. Which of the following is the number of Kanban card sets necessary to support this situation? @SeeChapter 12, page 416. Using equation 12.1: k = 150 x 2 x 1.25/8 = 46.875 = 47. (Points : 10) |
42 47 68 89 94 |
Question 9. 9. (TCO 7) Using the cut-and-try method for aggregate operations planning, we can determine the production requirement in units of product. If the beginning inventory is 100 units, the demand forecast is 1,200, and the necessary safety stock is 20% of the demand forecast, which of the following is the production requirement? @See Chapter 8, page 252. Demand = 1,200; 20% of demand = 240; Inventory = 100; produce 1,200 + 240 – 100 = 1,340. (Points : 10) |
1,200 1,300 1,340 1,500 1,540 |
Question 10. 10. (TCO 8) If annual demand is 6,125 units, annual holding cost is $5 per unit, and setup cost per order is $50, which of the following is the EOQ lot size? @See Chapter 9, page 290. From the equation: EOQ = 350 = Square root of (2 x 6125 x 50/5). (Points : 10) |
