One of his earlier contributions, presented in an article 1951, was the Hurwicz Criterion, which offers a formula for balancing optimism and pessimism when making decisions under uncertainty. The Department manager has to decide one of the types of . The Hurwicz alpha is a criterion for decision making under complete uncertainty that represents a comprimise between the Maximin and Maximax criteria. Decision making under uncertainty. Consequently, 1 - α determines our weighting on maximax. The coefficient of pessimissm, α, determines our weighting on maximin. [T] [F] The minimum expected opportunity loss is equal to the minimum regret. . D. D . where h_ {j} is the Hurwicz's criterion and \alpha is the coefficient of pessimism which fulfills the following condition: \alpha \in [0,1].
