This problem is especially relevant for Siberians. According to Greenpeace, Siberian forest fires in 2019 reached record levels in the entire history of observation in terms of burning area and the amount of carbon dioxide emitted into the atmosphere. It leads not only to a deterioration in the health of Siberians, but also to environmental problems of the region. Note that the large-scale fire-prevention measures entails enormous financial costs. Therefore, economical, ecological and mathematical modeling of the situations, arose in forest fires countering, becomes actual. The paper is devoted to optimal control problem of forest fires fighting. Its prototype is the well-known Parks model. To investigate the model, we apply the modern programming language Julia, which is designed to mathematical calculations and numerical studies. We made an extensive computational experiment in this model and a numerical analysis of corresponding optimal control problems. The obtained results were examined both on the adequacy of the model, and on the possibility of using the Julia language and the included solvers of mathematical problems.</p></abstract><trans-abstract xml:lang="ru"><p>Лесные пожары наносят серьезный ущерб экологическому состоянию и народному хозяйству страны. Эта проблема особенно актуальна для сибиряков. По данным Гринпис, лесные пожары в Сибири в 2019 году достигли рекордных за всю историю наблюдений уровней с точки зрения площади горения и количества выбросов углекислого газа в атмосферу. Это приводит не только к ухудшению здоровья сибиряков, но и к экологическим проблемам региона. Обратите внимание, что широкомасштабные противопожарные меры влекут за собой огромные финансовые затраты. Поэтому актуальным становится экономическое, экологическое и математическое моделирование ситуаций, возникших при противодействии лесным пожарам. Статья посвящена проблеме оптимального управления тушением лесных пожаров. Его прототипом является знаменитая модель Parks. Для исследования модели мы применяем современный язык программирования Julia, который предназначен для математических расчетов и численных исследований. Мы провели обширный вычислительный эксперимент в этой модели и численный анализ соответствующих задач оптимального управления. Полученные результаты были исследованы как на адекватность модели, так и на возможность использования языка Julia и включенных в нее решателей математических задач.</p></trans-abstract><kwd-group xml:lang="en"><kwd>forest fires fighting</kwd><kwd>mathematical modeling</kwd><kwd>optimal control</kwd><kwd>numerical analysis</kwd><kwd>Julia programming language</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>борьба с лесными пожарами, математическое моделирование, оптимальное управление, численный анализ, язык программирования Julia</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>A.
