Question
The Gorman Manufacturing Company must decide whether to manufacture a component part at its Milan, Michigan, plant or purchase the component part from a supplier. The resulting profit is dependent upon the demand for the product. The following payoff table shows the projected profit (in thousands of dollars):
State of Nature | |||
---|---|---|---|
Low Demand | Medium Demand | High Demand | |
Decision Alternative | s1 | s2 | s3 |
Manufacture, d1 | -20 | 40 | 100 |
Purchase, d2 | 10 | 45 | 70 |
The state-of-nature probabilities are P(s1) = 0.35, P(s2) = 0.35, and P(s3) = 0.30.
- Use a decision tree to recommend a decision.
Recommended decision:
-
- Use EVPI to determine whether Gorman should attempt to obtain a better estimate of demand.
-
EVPI: $ fill in the blank 3 - A test market study of the potential demand for the product is expected to report either a favorable (F) or unfavorable (U) condition. The relevant conditional probabilities are as follows:
P(F | s1) = 0.10 P(U | s1) = 0.90 P(F | s2) = 0.40 P(U | s2) = 0.60 P(F | s3) = 0.60 P(U | s3) = 0.40
What is the probability that the market research report will be favorable? If required, round your answer to three decimal places.
P(F) = fill in the blank 4 - What is Gorman's optimal decision strategy?
Decision strategy:
If F then
.
If U then
-
- What is the
expected value of the market research information?
Expected value: $ fill in the blank 7 - What is the efficiency of the information? If required, round your answer to one decimal place.
Efficiency: fill in the blank 8%
