Question 1. Munson Performance Auto, Inc., modifies 375 autos per year. The manager, Adam Munson, is interested in obtaining a measure of overall performance. He has asked you to provide him with a multifactor measure of last years performance as a benchmark for future comparison. You have assembled the following data. Resource inputs were labor, 10,000 hours; 500 suspension and engine modification kits; and energy, 100,000 kilowatt-hours. Average labor cost last year was $20 per hour, kits cost $1,000 each, and energy cots were $3 per kilowatt-hour. What do you tell Mr. Munson?

Question 2. Charles lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 25% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only thing to be changed. If the bakery makes 1,500 loaves per month with a labor productivity of 2,344 loaves per labor-hour, how many workers will lackey need to add? Each worker works 160 hours per month.

Question 3 Ranga Ramasech is the operation manager for a firm that is trying to decide which one of four countries it should research for possible outsourcing providers. The first step is to select a country based on cultural risk factors, which are critical to eventual business success with the provider. Ranga has reviewed outsourcing provider directories and found that the four countries in the table that follows have an ample number of providers from which they can choose. To aid the country selection step, he has enlisted the aid of a cultural expert, John Wang, who has provided rating of the various criteria in the table. The resulting rating are on a 1 to 10 scale, where 1 is a low risk and 10 is a high risk.

John has also determined six criteria weightings: Trust, with a weight of 0.4: Quality, with 0.2; Religious, with 0.1; Individualism, with 0.1; Time, with 0.1; and Uncertainty, with 0.1. Using the factor-rating method, which country should Ranga select?

Culture Selection Criterion	Mexico	Panama	Costa Rica	Peru
Trust	1	2	2	1
Society Value of Quality Work	7	10	9	10
Religiuos Attitudes	3	3	3	5
Individual Attitudes	5	2	4	8
Time Orientation Attitudes	4	6	7	3
Uncertainty Avoidance Attitudes	3	2	4	2

Question 5. The actual demand for the patients at Omaha Emergency Medical Clinic for the first 6 weeks of this year follows:

Week	Actual No. of Patients
1	65
2	62
3	70
4	48
5	63
6	52

Clinic administrator Marc Schniederjans wants you to forecast patient demand at the clinic for week 7 by using this data. You decide to use a weighed moving average method to find this forecast. Your method uses four actual demand levels, with weights of 0.333 on the present period, 0.25 one period ago, 0.25 two periods ago, and 0.167 three periods ago.
a. What is the value of your forecast?
b. If instead the weights were 20, 15, 15, and 10, respectively, how would the forecast change? Explain why.
c. What if the weights were 0.40, 0.30, 0.20, and 0.10, respectively? Now what is the forecast for week 7?

Question 6. Prepare a product-by-value analysis for the following products, and given the position in its life cycle, identify the issues likely to confront the operations manager and his or her possible actions. Product Alpha has annual sales of 1,000 units and a contribution of $2,500; it is in the introductory stage. Product Bravo has annual sales of 1,500 units and contribution of $3,000; it is in the growth stage. Product Charlie has annual sales of 3,500 units and a contribution of $1,750; it is in the decline stage.

a. What percentage of those surveyed found nothing they dislike?
b. Draw a Pareto chart summarizing these responses. Include the "no complaints" group.
