Question:
BBT is considering migrating their servers to a cloud service, upgrading their existing servers, or doing nothing. A payoff table (in $ millions) is provided in the accompanying spreadsheet. Using that table, answer the following questions:
- What is the EMV of each alternative? Based on this analysis, what is the best decision?
- Assume that the probabilities given are not reliable, then compute the criteria below and give the best decision for each.
- Maximin
- Maximax
- Equally likely (Laplace)
- Minimax regret
- Based on your analysis in 1 and 2, what do you recommend? Defend your answer!
Poor Market | Average Market | Good Market | |
Cloud | -5 | 21 | 29 |
Upgrade Servers | 10 | 15 | 27 |
Do nothing | 0 | -9 | -15 |
0.29 | 0.53 | 0.18 |
Provide the value of the criterion and the associated decision. For example, for #1, an answer could be Best EMV = 100; Decision = Do nothing.
