The term "digital twin" refers to a virtual representation of a physical object or system, allowing for real-time simulation and analysis. This technology uses data from sensors and IoT devices to create accurate models that replicate the physical counterpart's characteristics and behaviors. Digital twins are used in various industries, including manufacturing, healthcare, and smart cities, for purposes such as predictive maintenance, performance optimization, and system design. By enabling data-driven decision-making and enhancing operational efficiencies, digital twins are revolutionizing how businesses approach engineering and management.
