*Profit in thousands of dollars
With no knowledge of the probabilities, how much would you stock? Why? If you think each scenario is equally likely what would be the best stocking policy?
In an effort to reach a decision on purchase and stocking you have obtained the following information from a compilation of reports and articles in trade journals. You classified the market in five categories from worst to best (1-5). Probabilities for having each category of market were estimated as follows:
Category 1. .10
2. .20
3. .50
4. .10
5 .10
a. Given this information, what would be the best stocking policy?
b. What is the expected value of perfect information for this situation?
c. If new information causes you to revise the probabilities for market condition 2 to .28 and market condition 5 to .02 would you change your decision? If so, how would you change it?
