Digital twins couple computational models with physical systems to enable services such as predictive reasoning and runtime analysis that support decision–making for maintenance, optimisation and system evolution. They create a technically rich setting for applying formal methods throughout the system lifecycle beyond design-time. This tutorial introduces the elements of digital twin technology, identifying emerging opportunities for formal techniques, including the verification of evolving models under uncertainty, integration of heterogeneous models and rigorous composition of digital twin-enabled systems.

摘要

Digital twins couple computational models with physical systems to enable services such as predictive reasoning and runtime analysis that support decision–making for maintenance, optimisation and system evolution. They create a technically rich setting for applying formal methods throughout the system lifecycle beyond design-time. This tutorial introduces the elements of digital twin technology, identifying emerging opportunities for formal techniques, including the verification of evolving models under uncertainty, integration of heterogeneous models and rigorous composition of digital twin-enabled systems.
