```									BA520 QA Week 3 – Decision Analysis

Dr. Steve Tvorik, Instructor

Chapter 3: Problems 3-17, 3-19, 3-22, 3-23, 3-28, 3-29, 3-32, 3-40, 3-41, and 3-42.

3.17      Although Ken Brown is the principal owner of Brown Oil, his brother Bob is credited with making
the company a financial success. Bob is vice president of finance. Bob attributes his success to his
pessimistic attitude about business and the oil industry. Given the information from problem 3-16, it is
likely that Bob will arrive at a different decision. What decision criterion should Bob use, and what
alternative will he select?

Equipment                        Favourable Mkt(\$)                     Unfavourable Mkt(\$)

Sub 100                          \$ 300,000.00                          \$(200,000.00)
Oiler J                          \$ 250,000.00                          \$(100,000.00)
Texan                            \$ 75,000.00                           \$ (18,000.00)

SOLUTION: Ken is using MAXIMAX criterion and should select Sub 100 because it has the maximum
payoff of \$300000. As Bob is more pessimistic, He should use MAXIMIN criterion.

Equipment               Favourable Mkt(\$)              Unfavourable Mkt(\$)          Row minimum

Sub 100                 \$      300,000.00             \$ (200,000.00)           \$ (200,000.00)
Oiler J                 \$      250,000.00             \$ (100,000.00)           \$ (100,000.00)
Texan                   \$       75,000.00             \$ (18,000.00)            \$ (18,000.00)
Maximin \$ (18,000.00)
Using Maximin criterion, Bob Brown would select Texan as the worst payoff, since this alternative is better
than the
