Приведено математическое описание процесса олигомеризации этилена на катализаторе NiO/B2O3-Al2O3 в среде жидкого растворителя гептана. Сформулированы задачи оптимального управления процессом. В качестве управляющих параметров приняты температура и время протекания процесса. Предложен алгоритм решения задачи оптимального управления промышленно значимым каталитическим процессом олигомеризации этилена. Метод. Поиск решения сформулированных задач осуществляется с применением генетического алгоритма с вещественным кодированием. Для каждой из рассматриваемых задач предложен способ представления математического аналога популяции, на основе которого выполняется поиск решения. Представлен пошаговый алгоритм определения оптимальных значений параметров процесса олигомеризации этилена. Особенностью алгоритма является одновременный поиск значений непрерывного параметра управления (температура) и дискретного параметра управления (время процесса). Разработана программа (приложение), позволяющая определить оптимальные значения параметров процесса. Приложение позволяет пользователю выбирать задачу оптимального управления, задавать значения параметров генетического алгоритма для поиска решения и визуализировать полученные результаты. Основные результаты. Проведен вычислительный эксперимент для процесса олигомеризации этилена. Рассчитана оптимальная продолжительность процесса в изотермических условиях, при которой достигается наибольшее значение концентрации углеводородов C4. Определены оптимальные температурный режим и продолжительность процесса олигомеризации этилена, обеспечивающие максимальную концентрацию углеводородов С6. Обсуждение. Проведенные численные эксперименты продемонстрировали меньшую ресурсозатратность, по сравнению с методами равномерного поиска и вариаций в пространстве управления. Предложенный алгоритм можно применять для исследования закономерностей протекания каталитических процессов, не прибегая к проведению лабораторных экспериментов, сопряженных с дополнительными материальными и временными затратами.</p></abstract><trans-abstract xml:lang="en"><p>A mathematical description of the process of ethylene oligomerization on a NiO/B2O3-Al2O3 catalyst in a liquid heptane solvent is given. Problems of optimal process control are formulated. The temperature and time of the process are taken as control parameters. An algorithm is proposed for solving the problem of optimal control of the industrially significant catalytic process of ethylene oligomerization. The search for solutions to the formulated problems is carried out using a genetic algorithm with real coding. For each of the problems under consideration, a method is proposed for representing a mathematical analogue of a population on the basis of which a solution is searched. A step-by-step algorithm for determining the optimal parameters for the ethylene oligomerization process is presented. A special feature of the algorithm is the simultaneous search for the values of a continuous control parameter (temperature) and a discrete control parameter (process time). A program (application) has been developed to determine the optimal values of process parameters. The application allows the user to select an optimal control problem, set the values of the genetic algorithm parameters to find a solution, and visualize the results obtained. A computational experiment was carried out for the process of ethylene oligomerization. The optimal duration of the process under isothermal conditions was calculated, at which the highest concentration of C4 hydrocarbons is achieved. The optimal temperature conditions and duration of the ethylene oligomerization process were determined to ensure the maximum concentration of C6 hydrocarbons. The conducted numerical experiments demonstrated lower resource consumption compared to the methods of uniform search and variations in the control space. The proposed algorithm can be used to study the patterns of catalytic processes without resorting to laboratory experiments associated with additional material and time costs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>задача оптимального управления</kwd><kwd>олигомеризация этилена</kwd><kwd>генетический алгоритм</kwd><kwd>математическая модель</kwd><kwd>программное обеспечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optimal control problem</kwd><kwd>ethylene oligomerization</kwd><kwd>genetic algorithm</kwd><kwd>mathematical model</kwd><kwd>software</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 24-21-00186, https://rscf.ru/project/24-21-00186/.</funding-statement><funding-statement xml:lang="en">The research was supported by the Russian Science Foundation (RSF) grant No. 24-21-00186, https://rscf.ru/en/project/24-21-00186/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Джамбеков А.М., Щербатов И.А.
