Research on the Conceptual Architecture and Constituent Elements of Digital Twin System

With the rapid development and widespread application of cutting-edge information technology, digital twins have moved from technical concepts to practical applications. As one of the core supporting technologies for future intelligent warfare, digital twin has the characteristics of data-driven, real-time interaction, virtual real integration, iterative operation, predictive optimization, and auxiliary decision-making. It is regarded as a disruptive technology that promotes a new round of military revolution and changes the "rules of the future war game". The article describes the conceptual model of digital twins, introduces the reference architecture of digital twin systems, analyzes the constituent elements and main functions of target entities, twin interactions, digital entities, and service applications in digital twin systems.
