Defining the Relative Weights of the Alternatives Estimation Criteria Based on Clear and Fuzzy Rankings

摘要

An approach to the calculation of the weights of alternatives estimation criteria based on the experience of their multicriteria ranking, is proposed. It is believed that when it is difficult for an expert to estimate the alternatives and criteria weights cardinally, or by appropriate paired comparisons, one can search criteria weights based on the previous experience of ordinal estimation of alternatives by the specified criteria. The idea and a few modifications of the computation method of the weights are described, as well as the way of its generalization to the case when the expert judgments are given in the form of the fuzzy rankings of alternatives.
