A Digital Twin is a digital model that mirrors a physical entity to enable simulation, testing, monitoring, and maintenance in a virtual environment.
- Context:
- It can utilize advances in Computing Power and Data Digitization, making it increasingly accessible and cost-effective due to trends predicted by Moore's Law.
- It can provide a detailed and up-to-date Virtual Representation of the physical object's state, including its shape, position, status, and motion.
- It can be reprogrammable and smart, enabling physical products to be adjusted or optimized based on data collected by the digital twin.
- It can offer modularity in manufacturing, allowing for the design and customization of products and production modules.
- It can trace digital footprints, aiding in diagnosing problems or improving product designs.
