They were analyzed using computer models that implement the process of information dissemination in social communities. The typology of the most relevant and cited tools made possible to find an effective algorithm for implementing the authors’ agent-oriented model that takes into account individual characteristics of people and allows differentiated assessment of the impact of information messages only on a certain group. Within the framework of computational experiments, the speed of information dissemination in the constructed digital twin of a social network was estimated depending on the change in the number of opinion leaders and the number of initially informed agents, as well as on the decrease in the average level of reputation of network agents. The instrument designed may be used separately, as well as along within the complex models, including demographic and economic components.</p></abstract><trans-abstract xml:lang="ru"><p>В работе рассматриваются информационные войны, являющиеся частью современных гибридных конфликтов. Их анализ проведен средствами компьютерных моделей, имитирующих процесс распространения информации в социальных сообществах. Типология наиболее релевантных и цитируемых инструментов позволила определить эффективный алгоритм для создания авторской агент-ориентированной модели, учитывающей индивидуальные особенности людей и позволяющей давать дифференцированную оценку влияния информационных сообщений на определенную группу. В рамках вычислительных экспериментов оценивалась скорость распространения информации в построенном цифровом двойнике социальной сети в зависимости от изменения числа лидеров мнений и изначально информированных агентов, а также от снижения среднего уровня репутации агентов сети. Построенный инструмент может использоваться самостоятельно, но также и в составе более сложных моделей, включающих демографическую и экономическую составляющие.</p></trans-abstract><kwd-group xml:lang="en"><kwd>agent-oriented models</kwd><kwd>simulation of information dissemination</kwd><kwd>hybrid wars</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>агент-ориентированные модели</kwd><kwd>моделирование распространения информации</kwd><kwd>гибридные войны</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Акопов А.
