An algorithm was implemented for calculating integral ranking indices for fuzzy sets that characterize weather conditions in the computer mathematics program Maple2021, with the help of the LinearAlgebra library. It was shown that if the atmospheric pressure is not very high, the next day will be "sunnier", than in the case when the pressure is "very low". It was confirmed that integral ranking indices give more accurate information than deterministic ranking indices.</p></abstract><trans-abstract xml:lang="ru"><p>В статье проводится компьютерное моделирование погодных условий на основе данных атмосферного давления с привлечением теории нечетких множеств. В среде компьютерной математики Maple2021 с привлечением библиотеки линейной алгебры LinearAlgebra был реализован алгоритм расчета детерминированных и интегральных индексов ранжирования для нечетких множеств, которые характеризуют погодные условия. Исследования показали, что при умеренном атмосферном давлении на следующий день наблюдается более солнечная погода по сравнению с ситуацией, когда давление крайне низкое. На конкретных примерах было показано, что интегральные индексы ранжирования обеспечивают более точные результаты, чем детерминированные индексы ранжирования.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модель</kwd><kwd>нечеткие множества</kwd><kwd>интегральные индексы ранжирования</kwd><kwd>неопределенность</kwd><kwd>алгоритм</kwd><kwd>Maple2021</kwd><kwd>атмосферное давление</kwd><kwd>погода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>model</kwd><kwd>fuzzy sets</kwd><kwd>integral ranking indices</kwd><kwd>uncertainty</kwd><kwd>algorithm</kwd><kwd>Maple2021</kwd><kwd>atmospheric pressure</kwd><kwd>weather</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках программы «Приоритет-2030»</funding-statement><funding-statement xml:lang="en">The study was conducted within the framework of the Priority-2030 program</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zadeh L.A.
