The analysis of such systems requires tools to model various scenarios and predict the consequences of management decisions. The development of BRICS+ cooperation creates the preconditions for joint investments in the digitalization of healthcare and the transfer of operational process management technologies. The aim of the study is to develop a methodological approach to create a simulation model of an admission ward that provides formalization of stakeholder requirements and comprehensive analysis of ward workload. The methods include a review of existing approaches to patient flow modelling (discrete event, system dynamics, agent-based and hybrid models) and justification of the choice of discrete event approach as the most relevant to the tasks of operational management. Additionally, architectural modelling tools (ArchiMate, TOGAF) were applied to build a motivational model, which allowed structuring the goals, drivers and constraints of the process participants. The results consist in formalizing the requirements for the simulation model, defining its architecture and confirming the economic efficiency of its application. The model is shown to identify bottlenecks, optimize resource utilization, reduce waiting times and reduce costs. The results obtained are of practical value for shaping new vectors of BRICS+ countries’ cooperation in the field of high-tech medical services and management solutions. The novelty of the study lies in the combination of simulation and motivational modelling, which allows us to consider the emergency room as a complex adaptive system and create universal toolkits to support management decisions. This distinguishes this work from studies limited by separate methodological frameworks or lack of formalization of requirements.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность исследования связана с ростом нагрузки на медицинские учреждения и необходимостью повышения эффективности работы приемных покоев, где критично учитывать динамичность и сложность процессов поступления и распределения пациентов. Для анализа таких систем требуются инструменты, позволяющие моделировать различные сценарии и прогнозировать последствия управленческих решений. Развитие сотрудничества в рамках БРИКС+ создает предпосылки для совместных инвестиций в цифровизацию здравоохранения и трансфера технологий управления операционными процессами. Цель исследования - разработка методологического подхода к созданию имитационной модели приемного покоя, обеспечивающей формализацию требований заинтересованных сторон и комплексный анализ загруженности отделения. Методы включают обзор существующих подходов к моделированию потоков пациентов (дискретно-событийное, системная динамика, агентное моделирование и гибридные модели) и обоснование выбора дискретно-событийного подхода как наиболее релевантного задачам оперативного управления. Дополнительно применены средства архитектурного моделирования (ArchiMate, TOGAF) для построения мотивационной модели, что позволило структурировать цели, драйверы и ограничения участников процесса. Результаты заключаются в формализации требований к имитационной модели, определении ее архитектуры и подтверждении экономической эффективности применения. Показано, что модель позволяет выявлять «узкие места», оптимизировать использование ресурсов, сокращать время ожидания и снижать издержки. Полученные результаты представляют практическую ценность для формирования новых векторов сотрудничества стран БРИКС+ в сфере высокотехнологичных медицинских услуг и управленческих решений. Новизна исследования состоит в сочетании имитационного и мотивационного моделирования, что позволяет рассматривать приемный покой как сложную адаптивную систему и создавать универсальные инструментальные комплексы для поддержки управленческих решений. Это отличает данную работу от исследований, ограниченных отдельными методологическими рамками или отсутствием формализации требований.</p></trans-abstract><kwd-group xml:lang="en"><kwd>data management</kwd><kwd>simulation modeling</kwd><kwd>adaptive systems</kwd><kwd>medical organization</kwd><kwd>BRICS+</kwd><kwd>healthcare investments</kwd><kwd>management solutions</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>управление данными</kwd><kwd>имитационное моделирование</kwd><kwd>адаптивные системы</kwd><kwd>медицинская организация</kwd><kwd>БРИКС+</kwd><kwd>инвестиции в здравоохранение</kwd><kwd>управленческие решения</kwd></kwd-group><funding-group/></article-meta><fn-group/></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Alenany, E., &amp; Cadi, A.A.E.
