8.2. "The Long Commute": The Adams family of four lives east of Los Angeles in a middle-class community. Tom Adams's commute to work is 45 miles each way to downtown L.A. and he is not in a car- or vanpool. He has been thinking about chang- ing to a job closer to his home but has been working for over a year on a project that, if successfully completed, could lead to a major promotion. Unfortunately, there is a major defect in the product, which has yet to be located and corrected. Tom must solve the problem in the very near future because the delivery date promised to potential customers is a month away. Tom's financial security is heavily dependent on this promotion because of rising costs at home. Both children need braces for their teeth, he is in need of a new car (it broke down twice on the freeway this past fall), the house is in need of painting, and there is a water leak in the basement that he has not been able to repair. Sarah, Tom's wife, a mechanical engineer, has been considering getting a part-time job, but there are no engineering jobs available in the community. Full-time posi- tions are available in northern L.A., but this would pose major problems with respect to chauffeuring and managing the children. There are a couple of day-care centers in the community, but rumor has it they are very substandard. In addition, last year, their son Alex was accepted as a new student by the premier piano teacher in the area and there is no public transportation from their home to his studio. Melissa is very sad at the thought of giving up her YMCA swimming team and her Girl Scout troop, which both meet after school. Carry out a K.T. situation analysis on the Adams family's predicaments. ORC 8.8. "Buying a Car": You have decided you can spend up to $12000 to buy a new car. Prepare a K.T. decision analysis table to decide which car to buy. Use your local newspaper to collect information about the various models, pricing, and options and then decide on your musts (e.g., air bag) and your wants (e.g., quadraphonic stereo, CD player). How would your decision be affected if you could spend only $9000? What about $18000? 8.16. "Safety in the Plant": A reactor approximately 6 feet in diameter and 20 feet high in an ammonia plant had to be shut down to repair a malfunctioning nozzle. The nozzle could be repaired only by having a welder climb inside the reactor to carry out the repair. During welding, the oxygen concentration was regularly monitored. Four hours after the welding was completed, a technician entered the reactor to take pictures of the weld. The next day he was found dead in the reactor. Prepare a potential problem analysis table that could have prevented this accident.
