Mick Karra is the manager of MCZ Drilling Products, which produces a variety of specialty valves for oil field equipment. Recent activity in the oil fields has caused demand to increase drastically, and a decision has been made to open a new manufacturing facility. Three locations are being considered, and the size of the facility would not be the same in each location. Thus, overtime might be necessary at times. The following table gives the total monthly profit (in $1,000s) for each possible location under each demand possibility. The probabilities for the demand levels have been determined to be 20% for low demand, 30% for medium demand, and 50% for high demand.

Given data:
PAYOFFS (in $1000) | |||
Outcomes | |||
Alternatives | Demand is Low | Demand is Medium | Demand is High |
Ardmore, OK | 85 | 90 | 110 |
Sweetwater, TX | 110 | 100 | 120 |
Lake Charles, LA | 150 | 120 | 130 |
Optimistic criterion is the selection of the maximum of the maximum of all the courses of action. Also called as maximax criterion. The selection is done as shown in the table below:
PAYOFFS (in $1000) | |||||
Outcomes | |||||
Alternatives | Demand is Low | Demand is Medium | Demand is High | Maximum of the options available | Maximum of the max course of action |
Ardmore, OK | 85 | 90 | 110 | 110 | 150 |
Sweetwater, TX | 110 | 100 | 120 | 120 | |
Lake Charles, LA | 150 | 120 | 130 | 150 |
Hence under the optimistic criterion the location Lake Charles, LA is chosen with payoff values of $1,500,000
2. Which location would be selected based on the pessimistic criterion?
Under the pessimistic criterion, the decision maker chooses the action whose maximum loss is better than the least loss of all the other courses of action possible. Also referred to as the minimax criterion. In our case, we refer maximum loss as least profit and least loss as maximum profit. Hence the table follows as shown below:
PAYOFFS (in $1000) | |||||
Outcomes | |||||
Alternatives | Demand is Low | Demand is Medium | Demand is High | Least of the possible courses of action available | Maximum of the max course of action |
Ardmore, OK | 85 | 90 | 110 | 85 | 120 |
Sweetwater, TX | 110 | 100 | 120 | 100 | |
Lake Charles, LA | 150 | 120 | 130 | 120 |
Hence under the pessimistic criterion the location Lake Charles, LA is chosen with payoff values of $1,200,000
3. Which location would be selected based on the equally likely criterion?
Under this criterion, the decision maker maximizes the average payoff. The average payoff is calculated as shown below for Ardmore, OK location = = 95
Similarly for other location ss as follows:
PAYOFFS (in $1000) | |||||
Probabilities associated | 0.2 | 0.3 | 0.5 | ||
Outcomes | |||||
Alternatives | Demand is Low | Demand is Medium | Demand is High | Average | Best of averages |
Ardmore, OK | 85 | 90 | 110 | 95 | 133 |
Sweetwater, TX | 110 | 100 | 120 | 110 | |
Lake Charles, LA | 150 | 120 | 130 | 133 |
Hence under the equally likely criterion the location Lake Charles, LA is chosen with payoff values of $1,330,000
4. Which location would be selected based on the realism criterion? (α=0.6)
Under this criterion, the decision maker finds a compromise between the best and worst payoffs by choosing the best-weighted average based on the value of alpha called as the coefficient of realism.
= 0.60 is for best payoff and 1- = 0.40 is for the worst payoff.
Hence weighted average for example of Artmore, OT is * best payoff Ardmore + (1-) * worst payoff for Ardmore = 0.60 * 110 + 0.40 * 85 = 100 (in $1000)
Similarly, for other location, the table follows:
PAYOFFS (in $1000) | |||||
Probabilities associated | 0.2 | 0.3 | 0.5 | ||
Outcomes | |||||
Alternatives | Demand is Low | Demand is Medium | Demand is High | Weighted average | Best of averages |
Ardmore, OK | 85 | 90 | 110 | 100 | 138 |
Sweetwater, TX | 110 | 100 | 120 | 112 | |
Lake Charles, LA | 150 | 120 | 130 | 138 |
Hence under the realistic criterion the location Lake Charles, LA is chosen with payoff values of $1,380,000
5. Which location would be selected based on Expected Monetary Value (EMV)?
Under this category, the highest value of EMV for each location is selected. EVM is calculated as below:
For example the EVM payoff for Ardmore, OK = Pr(Low) * Payoff for low demand at Ardmore + Pr(Med) * Payoff for Med demand at Ardmore + Pr(High) * Payoff for High demand at Ardmore = 0.20 * 85 + 0.30 * 110 + 0.50 * 150 = $99 (in$1000).
Hence for other locations is as follows:
PAYOFFS (in $1000) | |||||
Probabilities associated | 0.2 | 0.3 | 0.5 | ||
Outcomes | |||||
Alternatives | Demand is Low | Demand is Medium | Demand is High | Expected Monetary value | Best of averages |
Ardmore, OK | 85 | 90 | 110 | 99 | 131 |
Sweetwater, TX | 110 | 100 | 120 | 112 | |
Lake Charles, LA | 150 | 120 | 130 | 131 |
Hence under the EVM criterion the location Lake Charles, LA is chosen with payoff values of $1,310,000

The Lake Placid Town Council decided to build a new community center to be used for conventions, concerts, and other public events, but considerable controversy surrounds the appropriate size. Many influential citizens want a large center that would be a showcase for the area. But the mayor feels that if demand does not support such a center, the community will lose a large amount of money. To provide structure for the decision process, the council narrowed the building alternatives to...
