What is the minimax regret rule?
The minimax regret strategy is the one that minimises the maximum regret. It is useful for a risk-neutral decision maker. Essentially, this is the technique for a ‘sore loser’ who does not wish to make the wrong decision.

What is the Maximax decision rule?
The Maximax Decision Rule. The Maximax decision rule is used when a manager wants the possibility of having the highest available payoff. It is called Maximax beacuse the manager will find the decision alternative that MAXImizes the MAXimum payoff for each alternative.
What is the best decision based on minimax regret?
3
Make the regret table by subtracting the values of each column from the corresponding highest payoffs. Then, collect the maximum value of each row separately in the last column. 13 is the minimum corresponding to decision 3. Thus, according to the minimax criterion, the best decision is 3.
What is maximin method?
A maximin strategy is a strategy in game theory where a player makes a decision that yields the ‘best of the worst’ outcome. All decisions will have costs and benefits, and a maximin strategy is one that seeks out the decision that yields the smallest loss.
How is Maximax criterion calculated?
Maximax Criterion You simply look at the best you could do under each action (the largest number in each column). You then take the best (largest) of these. The largest payoff if you buy 20, 40, 60, and 80 bicycles are $550, 1270, 2050, and 2330 respectively.
What is the maximin decision?
The Maximin decision rule is used for a risk-averse manager, who wants to minimize the possibility of having a poor outcome. It is called Maximin because the manager will find the decision alternative that MAXImizes the MINimum payoff. Note that this is clearly a risk-reducing decision.
What is Maximax maximin and minimax?
The maximax payoff criterion seeks the largest of the maximum payoffs among the actions. The maximin payoff criterion seeks the largest of the minimum payoffs among the actions. The minimax regret criterion seeks the smallest of the maximum regrets among the actions.
What is the recommended decision using optimistic conservative and minimax regret approaches?
The decision d2 gives the conservative approach because it has the largest minimum profit. The minimax regret is the decision d1 because it minimizes the maximum regret….Explanation of Solution.
| Decision | Maximum Profit | Minimum Profit |
|---|---|---|
| d2 | 100 | 75 |

What is minimax regret criterion?
Minimax Regret Criterion The Minimax Regret Criterion is a technique used to make decisions under uncertainty. The context of a decision making process under uncertainty, a decision maker is faced to uncertain states of nature and a number of decision alternatives that can be chosen.
How is Minimax regret calculated? The Minimax Regret Criterion is a technique used to make decisions under uncertainty. Under this Minimax Regret Criterion, the decision maker calculates the maximum opportunity loss values (or also known as regret) for each alternative, and then she chooses the decision that has the lowest maximum regret.
What is the maximax decision?
Maximax is an approach to a potential decision that attempts to maximize the potential return. If there is more than one potential outcome to a decision and the probability of each occurrence is not predictable or irrelevant to the decision-maker, this approach will simply look at the stated value of the outcome.
