The architectural features, operating principles and key components of such systems are analyzed. The essence of a digital twin is revealed as a virtual copy of a physical object capable of reflecting its state and predicting behavior in real time. Particular attention is paid to the methods of collecting, processing and analyzing data, as well as the use of machine learning algorithms to build accurate predictive models. The article presents the main performance metrics and quality indicators used to evaluate models for predicting failures and the remaining life of equipment. Practical examples and industry cases of successful implementation of IIMS based on digital twins in such areas as mechanical engineering, energy and transport are considered. As a practical implementation, the concept of a hardware and software complex for monitoring and collecting statistical data on technological processes is proposed. The article demonstrates that the integration of digital twins into information and measuring systems is a promising direction for increasing the reliability, efficiency and economic feasibility of industrial equipment operation due to the transition from reactive and planned preventive maintenance strategies to a proactive, predictive approach.</p></abstract><trans-abstract xml:lang="ru"><p>В статье рассматривается концепция применения интеллектуальных информационно-измерительных систем (ИИИС), построенных на базе технологии цифровых двойников, для решения задач предиктивного обслуживания промышленного оборудования. Анализируются архитектурные особенности, принципы функционирования и ключевые компоненты таких систем. Раскрывается сущность цифрового двойника как виртуальной копии физического объекта, способной в реальном времени отражать его состояние и прогнозировать поведение. Особое внимание уделяется методам сбора, обработки и анализа данных, а также применению алгоритмов машинного обучения для построения точных предиктивных моделей. В статье представлены основные метрики эффективности и показатели качества, используемые для оценки моделей прогнозирования отказов и остаточного ресурса оборудования. Рассмотрены практические примеры и отраслевые кейсы успешного внедрения ИИИС на основе цифровых двойников в таких сферах, как машиностроение, энергетика и транспорт. В качестве практической реализации предлагается концепция аппаратно-программного комплекса для мониторинга и сбора статистических данных о технологических процессах. Статья демонстрирует, что интеграция цифровых двойников в информационно-измерительные системы является перспективным направлением для повышения надежности, эффективности и экономической целесообразности эксплуатации промышленного оборудования за счет перехода от реактивных и планово-предупредительных стратегий обслуживания к проактивному, предиктивному подходу.</p></trans-abstract><kwd-group xml:lang="en"><kwd>intelligent information and measuring system</kwd><kwd>digital twin</kwd><kwd>predictive maintenance</kwd><kwd>industrial equipment</kwd><kwd>machine learning</kwd><kwd>condition monitoring</kwd><kwd>failure prediction</kwd><kwd>residual resource</kwd><kwd>Industry 4.0</kwd><kwd>hardware and software complex</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>интеллектуальная информационно-измерительная система</kwd><kwd>цифровой двойник</kwd><kwd>предиктивное обслуживание</kwd><kwd>промышленное оборудование</kwd><kwd>машинное обучение</kwd><kwd>мониторинг состояния</kwd><kwd>прогнозирование отказов</kwd><kwd>остаточный ресурс</kwd><kwd>Industry 4.0</kwd><kwd>аппаратно-программный комплекс</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Zhilyakov A.A.
