A company currently using an inspection process in its material receiving department is trying to install an overall cost reduction program. One possible reduction is the elimination of one inspection position. This position tests items for which the probability of a material defect averages 0.01. By inspecting all items, the inspector is able to remove all defects. The inspector can inspect 50 units per hour. The hourly rate including fringe benefits for this position is $10. If the inspection position is eliminated, defects will go into product assembly and will have to be replaced later at a cost of $11 each when they are detected in final product testing.
Assume that the line will operate at the same rate (i.e., the inspection rate) if the inspection operation was eliminated.
a-1. If the inspector position is eliminated, what will the hourly cost of defects be? (Round your answer to 2 decimal places.)
Cost per hour $
a-2. Should this inspection position be eliminated based on costs alone?
Yes | |
No |
b. What is the cost to inspect each unit? (Round your answer to 2 decimal places.)
Cost per unit $
c. Is there benefit (or loss) from the current inspection process? How much? (Input all amounts as positive values. Round your answers to 2 decimal places.)

Nike Big Data Management
With the analysis on the business of this leader in the sports industry, it indicates that NIKE is facing a problem in how to market their customers in a more customized way in order to regain the market share for the young market especially.
According to the 5-forces, Nike is suffering from the great level of competitive rivalry in a saturated market. People within this market have very low cost in switching to other brands while competitors are having similar features on their products. Obviously, NIKE’s young market is losing loyalty to it, while Adidas, New Balance and Puma in sports and Vans, Converse and Supreme in streetwear performance are gaining momentum. It is possible to say that they are not only competing on shoes and clothes but also technologies and stylish design nowadays as customers and even retailers have so much to choose from.
On the other hand, NIKE seems to be ignoring some speciality sports retailers while retailers have deep ties to the young market and community. They act an important role in the distribution chain to help promote the brands. NIKE has to closely work with its retail partners like Foot Locker and even more on its 200+ NIKE stores or other speciality sports retailers.
Moreover, young customers usually go to these stores looking for advice on fitting and matching which means stores seriously affecting teenagers’ selection. In this case, the taste and value of the young customer may have been changed a lot in these couple years due to the influence of social media. Therefore, to regain larger market share and create higher profit, NIKE can use BDA on issues like “The most influential athlete to teenagers'', “The fashion color of the coming year”, “Hot icon or images in the world”, “How many hashtags on the product” and “Most popular Internet celebrity” etc. Although NIKE have been innovative for a long time and equipped with advanced technologies, only further customized marketing can take it up to a notch.

Design specifications require that a key dimension on a product measure 101 ± 8 units. A process being considered for producing this product has a standard deviation of five units.
a. What can you say (quantitatively) regarding the process capability? Assume that the process is centered with respect to specifications. (Round your answer to 4 decimal places.)
Process capability index
b. Suppose the process average shifts to 98. Calculate the new process capability. (Round your answer to 4 decimal places.)
New process capability index
c. What is the probability of defective output after the process shift? (Use Excel's NORM.S.DIST() function to find the correct probability. Round "z" values to 2 decimal places. Round probabilities to 4 decimal places (0.####).)
Probability of defective output

1. Precision Manufacturing, Inc. plans to open a new plant in Missouri. The company can open a full-sized plant now or a medium-sized plant now or a small-sized plant now depending on the levels of future demand. The future demand levels may be high, medium, or low. The following table gives the estimated annual income for each decision alternative under each level of future demand:

a. Which decision alternative should Precision Manufacturing select using the MAXIMAX approach? What is the corresponding annual income?
b. Which decision alternative should Precision Manufacturing select using the MAXIMIN approach? What is the corresponding annual income?
c. Which decision alternative should Precision Manufacturing select using the Laplace (or equally likely) approach? What is the corresponding annual income?
Precision’s analysis resulted in the following probabilities for the three future demand levels: P(high demand) = 0.70; P(medium demand) = 0.20; and P(low demand) = 0.10.
d. Construct a decision tree for this problem.
e. If maximum expected monetary value (EMV) is used as the decision criterion, which decision alternative should Precision Manufacturing select? What is the corresponding expected annual income?
f. Suppose a marketing research firm is trying to sell the perfect information about the future demand to Precision Manufacturing, which will help Precision select the best alternative. What would be the expected value of perfect information (EVPI) for Precision?
If the marketing research firm were asking $39,000 for the perfect information, would you advise Precision to buy the information? Explain your reasoning.
