Показываются достоинства и недостатки аксиоматики Сэвиджа в теории субъективной вероятности, анализируются модели формирования верований. Предлагается новый подход к анализу принятия решений - модель множественных первичных верований, в которой агент приписывает каждому событию диапазон вероятностей.</p></abstract><trans-abstract xml:lang="en"><p>The article considers the paradigm of subjective probability and expected utility theory with respect to their applications in the theory of decision-making. Advantages and shortcomings of Savage’s axiomatic in the subjective probability theory are analyzed, the models of beliefs formation are considered. The authors propose a new approach to the analysis of decision-making — a multiple priors model, where an agent attributes to each event not a single probability, but a range of probabilities.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теория субъективной вероятности</kwd><kwd>теория ожидаемой полезности</kwd><kwd>микроэкономическая теория</kwd><kwd>теория принятия решений</kwd><kwd>неопределенность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>subjective probability theory</kwd><kwd>expected utility theory</kwd><kwd>microeconomics</kwd><kwd>theory of decision-making</kwd><kwd>uncertainty</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Anscombe F.
