The Digital Twin Consortium updated its definition to stress synchronization, stating: 'A digital twin is an integrated data-driven virtual representation of real-world entities and processes, with synchronized interaction at a specified frequency and fidelity.' This highlights the importance of integration and data-driven representation.
The refined definition of a digital thread by the DTC emphasizes a seamless, interconnected information system linking various lifecycle stages. It underscores a trustworthy, bidirectional data flow across all organizations and stakeholders throughout the product life cycle.
Researchers are ambitiously working on creating digital twins of the entire planet. This could revolutionize our understanding of environmental dynamics, providing critical insights that could shape future environmental policies and methodologies.
NASA's Advanced Information Systems Technology programme aims for Earth's System Digital Twins (ESDT) to integrate diverse Earth and human activity models. This approach will enhance our understanding of interactions within environmental systems.
