The intended audience of the school includes master and PhD students as well as young researchers from the fields of computer science and mathematics.
Digital twin applications use digital artefacts to twin physical systems. The purpose is to continuously mirror the structure and behavior of the physical system, such that users can analyse the physical system by means of the digital twin for e.g., to give support for decision making, for systematic reconfiguration, etc. In this tutorial, we discuss what is a digital twin, and how it can be built in a framework that integrates semantic technology and simulation units. We also discuss how a digital twin can systematically reconfigure over time to mirror a changing physical system.
