Sample questions asked in the 11th edition of Operations Management:
Chuck’s Custom Boats (CCB) builds luxury yachts to customer order. CCB has landed a contract with a mysterious New York lawyer (Mr. T). Relevant data are shown below. The complication is that Mr. T wants delivery in 32 weeks or he will impose a penalty of $375 for each week his yacht is late. Note: No activity can be crashed more than two weeks. CRASHING COSTS Activity Immediate Predecessor Normal Time (weeks) 1st Week 2nd Week K — 9 $410 $415 L K 7 125 — N K 5 45 45 M L 4 300 350 J N 6 50 — Q J, M 5 200 225 P Q 8 — — Y Q 7 85 90 Z P 6 90 — End Y, Z Develop a crashing schedule.
A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used five workers, who produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour while output increased by four carts per hour. a. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. b. Compute the multifactor productivity under each system. Use carts per dollar cost (labor plus equipment) as the measure. c. Comment on the changes in productivity according to the two measures, and on which one you believe is the more pertinent for this situation.
A pharmacist has been monitoring sales of a certain over-the-counter pain reliever. Daily sales during the last 15 days were Day: 1 2 3 4 5 6 7 8 9 Number sold: 36 38 42 44 48 49 50 49 52 Day: 10 11 12 13 14 15 Number sold: 48 52 55 54 56 57 a. Which method would you suggest using to predict future sales—a linear trend equation or trend- adjusted exponential smoothing? Why? b. If you learn that on some days the store ran out of the specific pain reliever, would that knowledge cause you any concern? Explain. c. Assume that the data refer to demand rather than sales. Using trend-adjusted smoothing with an initial forecast of 50 for week 8, an initial trend estimate of 2, and ? = ? = .3, develop forecasts for days 9 through 16. What is the MSE for the eight forecasts for which there are actual data?
The classified department of a monthly magazine has used a combination of quantitative and qualitative methods to forecast sales of advertising space. Results over a 20-month period are as follows: Month Error Month Error 1 –8 11 1 2 –2 12 6 3 4 13 8 4 7 14 4 5 9 15 1 6 5 16 –2 7 0 17 –4 8 –3 18 –8 9 –9 19 –5 10 –4 20 –1 a. Compute a tracking signal for months 11 through 20. Compute an initial value of MAD for month 11, and then update it for each month using exponential smoothing with ? = .1. What can you conclude? Assume limits of ± 4. b. Using the first half of the data, construct a control chart with 2 s limits. What can you conclude? c. Plot the last 10 errors on the control chart. Are the errors random? What is the implication of this?
A company manufactures hair dryers. It buys some of the components, but it makes the heating element, which it can produce at the rate of 800 per day. Hair dryers are assembled daily, 250 days a year, at a rate of 300 per day. Because of the disparity between the production and usage rates, the heating elements are periodically produced in batches of 2,000 units. a. Approximately how many batches of heating elements are produced annually? b.If production on a batch begins when there is no inventory of heating elements on hand, how much inventory will be on hand two days later? c.What is the average inventory of elements, assuming each production cycle begins when there are none on hand? d.The same equipment that is used to make the heating elements could also be used to make a component for another of the firm’s products. That job would require four days, including setup. Setup time for making a batch of the heating elements is a half day. Is there enough time to do this job between production of batches of heating elements? Explain.
Productivity should be a concern of every business organization. a. How is productivity defined? b. How are productivity measures used? c. Why is productivity important? d. What part of the organization has primary responsibility for productivity? e. How is efficiency different from productivity?
