(4.5)
Critical Thinking Questions: (Marks 5)
Question 1: (1 Mark)
Suppose you are a member of a group asked to find ways to cut costs
throughout your organization for the upcoming year. Sales have
fallen sharply, and the company is in danger of going out of
business. After gathering information, your group concludes that
the company will save the most money by freezing pay for a year,
despite a tradition of annual salary increases. How can you make
sure this is a fair decision? How can you make sure that others in
the organization will see it as a fair decision?
Question 2: Case Analysis
Care, a health consultancy company in Saudi Arabia, is studying the
economic benefits of a program of preventative COVID-19 flu
vaccinations. Care has to give advice to government for COVID-19
vaccination. If vaccinations are not introduced then the estimated
cost to the government if flu strikes in the next year is SR.70m
with probability 0.1, SR.100m with probability 0.3 and SR.150m with
probability 0.6. It is estimated that such a program will cost
SR.70m and that the probability of flu striking in the next year is
0.75.
One alternative open to the committee is to institute an
"early-warning" monitoring scheme (costing SR.30m) which will
enable it to detect an outbreak of flu early and hence institute a
rush vaccination program (costing SR.100m because of the need to
vaccinate quickly before the outbreak spreads).
Question
• As a consultant of Care, Develop a decision tree for alternatives
and make recommendation to Indian government that which alternative
can maximize expected economic benefits?
Question 3: (1 Mark)
Decision support tools rely on objective, mathematical data. What
part does ethics play in using decision support software?
Question 4: (1 Mark)
If you collect too much information for analyzing a decision, you
can suffer from analysis paralysis, where you spend too much time
thinking about a decision rather than making one. Recall a major
financial decision you made recently, such as of a car or housing
purchase or rental. Describe your process for making the decision.
How could analysis paralysis have affected this process?

Franklin Furniture
Franklin Furniture produces tables and chairs at its East-side plant for use in university classrooms. The unit profit for tables is $70, while that for chairs is $30.
Tables and chairs are manufactured using finished pressed wood and polished aluminum fittings. Including scrap, each table uses 20 square feet of pressed wood, whereas each chair uses 12.5 square feet of the pressed wood. Franklin Furniture has 6000 square feet of the pressed weed available for the East-side plant weekly. The aluminum fittings that reinforce the legs of both the tables and chairs are purchased from an outside supplier. Franklin Furniture can purchase up to 400 boxes of fittings weekly; one box is required for each table or chair manufactured.
Production time is 72 minutes (1.2 hours) per table and 18 minutes (0.3 hours) per chair. Franklin Furniture has eight employees, each of whom works an average of 7.5 hours per day. Thus, in an average five-day work week, the company has available 8(7.5)(5) = 300 production hours.
Franklin Furniture also produces desks and computer workstations at its West-side plant. Each desk nets the company a profit of $100, while each computer workstation nets $125. These products are also produced from finished pressed wood and aluminum. The amount of each, as well as the labor time needed to produce a desk or computer workstation, is given in the following table.
Pressed Wood |
Aluminum Fittings | Labor | |
| Desk | 20 sq. ft. | 1 box | 1.5 hrs |
| Workstations | 30 sq. ft. | 1 box | 2.0 hrs |
|
Available |
6000 sq. ft. | 400 box | 300 hrs |
Franklin Furniture is considering combining operations of both plants into a single plant. This consolidation will combine the weekly available resources so that 12,000 square feet of pressed wood, 800 boxes of aluminum fittings, and 600 production hours will available weekly. However, the accounting department estimates the cost of renovating the plant will be $5000 per week, on an amortized basis.
In your role of a Business Consultant to Franklin Furniture, prepare a business report for Franklin Furniture giving optimal weekly production schedules for each of its plants operating separately. Then include an analysis and recommendation to Franklin Furniture for combining operations at both plants into a single plant.
(Hint: This case can be solved by splitting it into three small cases, two of which can be analyzed using only two decision variables.)

Rural County has a population of 15,000, a small primary care
hospital, and ten
physicians, including seven general and family practitioners, an
obstetrician, a pediatrician,
and a general surgeon. All the physicians are solo practitioners.
The nearest urban area is
about 60 miles away in Big City, which has a population of 300,000,
and three major
hospitals to which patients from Rural County are referred or
transferred for higher levels
of hospital care. However, Big City is too far away for most
residents of Rural County to
use for services available in Rural County.
Insurance Company, which operates throughout the state, is
attempting to offer
“managed care” programs in all areas of the state, and has asked
the local physicians in
Rural County to form an IPA to provide services under the program
to covered persons
living in the county. No other managed care plan has attempted to
enter the county
previously.
Initially, two of the general practitioners and two of the
specialists express interest in
forming a network, but Insurance Company says that it intends to
market its plan to the
larger local employers, who need broader geographic and specialty
coverage for their
employees. Consequently, Insurance Company needs more of the local
general practitioners
and the one remaining specialist in the IPA in order to provide
adequate geographic,
specialty, and backup coverage to subscribers in Rural County.
Eventually, four of the
seven general practitioners and the one remaining specialist join
the IPA and agree to
provide services to Insurance Company’s subscribers under contracts
providing for
capitation. While the physicians’ participation in the IPA is
structured to be nonexclusive,
no other managed care plan has yet entered the local market or
approached any of the
physicians about joining a different provider panel. In discussing
the formation of the IPA
with the Insurance Company, a number of the physicians have made
clear their intention
to continue to practice outside the IPA and have indicated they
would be interested in
contracting individually with other managed care plans when those
plans expand into Rural
County. Insurance Company requests your legal advice about whether
this network
formation is likely to be challenged by the federal government.
Discuss whether the network described in the Problem would likely be challenged by the federal government.
Why? On what legal basis?
What would be your response to a challenge?
Would factors increase or decrease your changes of a federal challenge?

You have entered a model rocket contest with your friend, Tiffany. You have been working on a pressurized rocket filled with nitrous oxide. Tiffany has determined the minimum atmospheric pressure at which the rocket fuel is stable. Based not hat value, and the equations given below, your task is to determine the optimum launch angle and initial velocity to maximize flight time. The goal is to re-use your rocket capsule, so you really want to avoid a fuel explosion.
The atmospheric pressure varies with elevation according to the equation: P(h)= 14.7e−h/10. where p is the pressure in psi and h, is an elevation in miles above sea levels. The height (in feet) of a rocket launched at an angle α degrees with the horizontal and an initial velocity, vo in feet/second, t seconds after launch is given by the equation h(t)=-16t^2+vo*t*sin(α).
1) If Tiffany has determined that the minimum safe pressure is 11 pounds per square inch, at what altitude will the rocket explode? Report your result in feet. Round to the nearest foot.
2) If the angle of launch is33o, with an initial velocity of 1,648 what is the minimum atmospheric pressure exerted on the rocket during its flight? Report your answer to one decimal place. Under these conditions, will the rocket explode during its flight?
3) If the angle of launch is32o, with an initial velocity of 1,908 what is the minimum atmospheric pressure exerted on the rocket during its flight? Report your answer to one decimal place. Under these conditions, will the rocket explode during its flight?
4) Tiffany has revisited her calculation and has now concluded that the minimum safe pressure for the fuel is 9 psi. What is the maximum height your rocket can achieve without exploding in flight? Report your answer in feet to the nearest foot.
5) Tiffany has (once again) checked her calculations, and you have verified with her that the safe pressure for your fuel is 9 and the fuel capsule holds enough fuel to produce an initial velocity of 2,169 feet per second. What launch angle will you use so that your rocket achieves the maximum safe altitude? Round your answer to the nearest tenth of a degree.
