Computing Fuzzy Variances of Evaluations of Alternatives in Fuzzy Decision Matrices
Original language description
Decision matrices are a common tool for solving decision-making problems under risk. Elements of the matrix express evaluations if a decision-maker chooses the particular alternative and the particular state of the world occurs. In practice, the states of the world as well as the decision-maker's evaluations are often described only vaguely. In the literature, there are considered fuzzy decision matrices, where alternatives are compared on the basis of the fuzzy expected values and fuzzy variances of their evaluations. However, the fuzzy variances of alternatives are calculated without considering dependencies between fuzzy evaluations under particular fuzzy states of the world and the fuzzy expected evaluation. So the final ranking of alternatives can be wrong. In the paper, we propose a proper way of how should the fuzzy variances of evaluations of alternatives be obtained. The problem is illustrated by the example of stocks comparisons.
