Abstract: Generation of a reduced order model (ROM)-based digital twin and presentation of an equipment system, subsystem or component using augmented reality, mixed reality or virtual reality is provided. Leveraging digital twin generation, artificial intelligence and machine learning analytics, and immersive augmented reality, mixed reality or virtual reality experiences enables a more realistic virtual maintenance and training environment.
