Even though independent gasoline stations have been having a difficult time, lan Langella has been thinking about starting his own independent gasoline station. Ian's problem is to decide how large his station should be. The annual returns will depend on both the size of his station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, lan developed the following table: Size of First Station Small Medium Large Very Large States of Nature Good Market Fair Market $60,000 $21,000 $70,000 $32,000 $95,000 $32,500 $280,000 $24,000 Poor Market - $12,000 - $18,000 - $42,000 - $150,000 For example, if lan constructs a small station and the market is good, he will realize a profit of $60,000. This exercise contains only parts b, c, and d. b) Using the decision making under uncertainty with the criterion of Maximax The appropriate decision will be Very Large The value of the return under this decision is $ 280000 . c) Using the decision making under uncertainty with the criterion of Maximin The appropriate decision will be Small The value of the return under this decision is $ 12000
