Abstract:

The article considers decision-making problems in a situation where the prior probabilistic information about the state of nature and decision maker's utility function are imprecisely defined. In such a case the risks (or the expected utility) of considered decisions are also imprecisely defined. A two-step procedure for finding the optimal decision has been proposed. First, possible decisions were ordered using the λ-average ranking method by Campos and Gonzalez. Then the possibilistic Possibility of Dominance and Necessity of Strict Dominance indices proposed by Dubois and Prade were used to compare the consequences of the most promising solutions.
