Выполнен сравнительный анализ производительности и точности метода MSTL и сезонной интегрированной модели авторегресионного скользящего среднего (SARIMA). Приведены результаты экспериментов, подтверждающие трудность построения модели SARIMA на данных с высокой степенью дискретизации и значениями периодов, превышающими классические сезонности, такие как 7, 12, 52. При построении модели SARIMA были наложены временные ограничения по подбору параметров вследствие высокого потребления памяти, что приводило к снижению точности прогноза и ограничению возможности построения модели на основе более высоких показателей сезонности. Метод MSTL демонстрирует преимущество по сравнению с моделью SARIMA по времени выполнения прогноза и потреблению памяти, однако на небольшом наборе исходных данных модель SARIMA показывает более высокую точность.</p></abstract><trans-abstract xml:lang="en"><p>The correctness of using the multi-seasonal season-trend decomposition method based on locally weighted scattergram smoothing for the problems of forecasting multi-seasonal load processes in elastic systems is as sessed. A comparative analysis of the performance and accuracy of the above method and the seasonal integrated auto regressive moving average (SARIMA) model is performed. Results of experiments are presented that confirm the difficul ty of constructing the SARIMA model based on data with a high degree of discretization and period values exceeding classical seasonality, such as 7, 12, 52. When creating the SARIMA model, time restrictions are imposed on the selec tion of parameters due to high memory consumption, which lead to a decrease in forecast accuracy and limited the abili ty to build a model based on higher seasonality indicators. The multi-seasonal season-trend decomposition method de monstrates an advantage over the SARIMA model in terms of forecast execution time and memory consumption, howev er, with a small set of initial data, the SARIMA model shows higher accuracy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эластичные системы</kwd><kwd>мультисезонные нагрузочные процессы</kwd><kwd>прогнозирование временных рядов</kwd><kwd>SARIMA</kwd><kwd>MSTL</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elastic systems</kwd><kwd>multi-seasonal workload</kwd><kwd>time series forecasting</kwd><kwd>SARIMA</kwd><kwd>MSTL</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">Aliev T.
