The basic axioms of ‘reasonable’ choice are formulated. They, in particular, allow us to establish the Edgeworth-Pareto principle for this class of problems. The concept of a quantum of interval fuzzy information is introduced, as well as a consistent set of similar quanta. A criterion for the consistency of a set of quanta is formulated and a scheme for using quanta of interval fuzzy information to reduce the Pareto set is presented. An example is given to illustrate the proposed approach.</p></abstract><trans-abstract xml:lang="ru"><p>Рассматривается класс задач многокритериального выбора, в которых предпочтения лица, принимающего решение, моделируются интервальным нечетким отношением второго порядка. Формулируются базовые аксиомы «разумного» выбора, которые, в частности, позволяют обосновать принцип Эджворта-Парето в этом классе задач. Вводится понятие кванта интервальной нечеткой информации, а также непротиворечивого набора подобных квантов. Сформулирован критерий непротиворечивости набора квантов и представлена схема использования интервальной нечеткой информации для сужения множества Парето. Разобран пример, иллюстрирующий предложенный подход.</p></trans-abstract><kwd-group xml:lang="en"><kwd>multicriteria choice</kwd><kwd>interval fuzzy relation</kwd><kwd>quantum of interval fuzzy information</kwd><kwd>consistency of quanta</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>многокритериальный выбор</kwd><kwd>интервальное нечеткое отношение</kwd><kwd>квант интервальной нечеткой информации</kwd><kwd>непротиворечивость квантов</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Noghin V.D.
