Multi-Criteria choice of Alternatives under Fuzzy Information

Abstract

The solution of the problem of multicriteria alternative choice in the conditions of fuzzy expert assessments of compliance with alternatives to the requirements of criteria is described. We consider the situation when the rating of the alternatives can comprise several experts that form an individual system of criteria for evaluation of alternatives using numerical or linguistic form submissions. The construction of a unified system of criteria is proposed to perform on the basis of assessing the truth of linguistic statements about the feasibility of the inclusion of criteria in a unified system, which subsequently identifies non-overlapping subsets of criteria that characterize the opportunities and threats in the implementation of alternatives. In contrast to the known studies, the final choice of the best alternative is based on the ratio of integral estimates according to the criteria characterizing opportunities and threats.
