Разработан вычислительный алгоритм, позволяющий проводить моделирование процессов, описываемых данным уравнением. Проведено тестирование и продемонстрирована эффективность вычислительной процедуры. Исследован процесс формирования диссипативных структур в зависимости от параметров модели. При помощи метода циклической свертки определен диапазон изменения управляющего параметра, при котором имеют место процессы самоорганизации, а также исследованы качественные и количественные характеристики рассматриваемого процесса. В частности получена зависимость амплитуды сформировавшейся структуры от величины управляющего параметра.</p></abstract><trans-abstract xml:lang="en"><p>In the present work, we study the features of dissipative structures formation described by the periodic boundary value problem for the Kuramoto-Sivashinsky equation. The numerical algorithm which is based on the pseudospectral method is presented. We prove the efficiency and accuracy of the proposed numerical method on the exact solution of the equation considered. Using this approach, we performed the numerical simulation of dissipative structure formations described by the Kuramoto–Sivashinsky equation. The influence of the problem parameters on these processes are studied. The quantitative and qualitative characteristics of dissipative structure formations are described. We have shown that there is a value of the control parameter at which the processes of dissipative structure formation are observed. In particular, using the cyclic convolution we define the average value of this parameter. Also, we find the dependence of the amplitude of the structures on the value of control parameter.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уравнение Курамото-Сивашинского</kwd><kwd>самоорганизация</kwd><kwd>структуры</kwd><kwd>псевдоспектральный метод</kwd><kwd>численное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Kuramoto–Sivashinsky equation</kwd><kwd>self–organization</kwd><kwd>patterns</kwd><kwd>pseudospectral method</kwd><kwd>numerical simulation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">грант для поддержки ведущих научных школ, РФФИ, грант для поддержки молодых ученых – кандидатов наук</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">Kuramoto Y., Tsuzuki T.
