Проведение планирования эксперимента для случаев двух и трех факторов на примере объектов топливно-энергетического комплекса.</p></sec><sec><title>Методы</title><p>Методы. Для повышения точности модели и учета нелинейности связи параметров применен ортогональный центральный композиционный план.</p></sec><sec><title>Результат</title><p>Результат. Выполнены расчеты параметров плана, составлены матрицы планирования, получены уравнения регрессии. Реализован двухфакторный эксперимент, позволивший построить адекватные квадратичные регрессионные модели для прогнозирования расхода и давления в системе транспортировки жидкости. Проведен трехфакторный эксперимент на основе секционной модели первичной переработки нефти. Факторы, влияющие на критерий: расход перегретого водяного пара, флегмовое число, потенциальное содержание светлых фракций в сырье. Инструментами реализации выбраны программные пакеты MatLab и Python. Выполнена оценка адекватности полученных регрессионных квадратичных зависимостей исходным данным по критерию Фишера.</p></sec><sec><title>Вывод</title><p>Вывод. Решена задача максимизации расхода жидкости в системе транспортировки жидкости. Проведенное исследование введения воздуха в циркулирующую вязкую жидкость можно рассматривать как удобную модель для изучения двухфазных потоков. Применение статистической модели на установках ректификации нефти способствует повышению эффективности функционирования установок.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To carry out experimental design for twoand three-factor cases using facilities of the fuel and energy complex as examples.</p></sec><sec><title>Methods</title><p>Methods. An orthogonal central composite design was applied to improve model accuracy and account for nonlinear relationships among parameters.</p></sec><sec><title>Results</title><p>Results. The design parameters were calculated, planning matrices were constructed, and regression equations were obtained. A two-factor experiment was implemented, yielding adequate quadratic regression models for predicting flow rate and pressure in a liquid-transport system. A three-factor experiment was conducted based on a sectional model of primary oil refining. The factors affecting the criterion were: superheated steam flow rate, reflux ratio, and potential content of light fractions in the feed. MatLab and Python software packages were used. The adequacy of the obtained quadratic regression relationships to the original data was evaluated by Fisher’s F-test.</p></sec><sec><title>Conclusions</title><p>Conclusions. The problem of maximizing liquid flow in the transport system was solved. The study of air injection into a circulating viscous liquid can serve as a convenient model for two-phase flow investigation. The application of the statistical model to oil rectification units contributes to improved operational efficiency of the installations.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>планирование эксперимента</kwd><kwd>статистическая модель</kwd><kwd>физическая модель</kwd><kwd>центральный композиционный план</kwd><kwd>нефть</kwd><kwd>расходомер</kwd><kwd>газовый фактор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>experimental design</kwd><kwd>statistical model</kwd><kwd>physical model</kwd><kwd>central composite design</kwd><kwd>oil</kwd><kwd>flow meter</kwd><kwd>gas factor</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">Рудин М.Г., Сомов В.Е., Фомин А.С.
