Fuzzy Decision Matrices Viewed as Fuzzy Rule-Based Systems
Original language description
A decision matrix represents a particular problem of decision making under risk. Elements of the matrix express the consequences if a decision-maker chooses a particular alternative and a particular state of the world occurs. Assuming the probabilities of the states of the world are known, alternatives are compared on the basis of the expected values and variances of their consequences. In practice, the states of the world are often described only vaguely; they are expressed by fuzzy sets on the universal set on which the probability distribution is given. In literature, the common approach in such a case consists in computing crisp probabilities of the fuzzy states of the world by formula proposed by Zadeh. In the paper, we first discuss the problems connected with the common approach. Consequently, we introduce a new approach, in which a decision matrix with fuzzy states of the world does not describe discrete random variables but fuzzy rule-based systems. We illustrate the problem by examples.
