A holistic approach to domain independent development of digital twins

2025-GRIN-38441

Abstract

Abstract

The use of Digital Twins (DT), which originated mainly in industry, is becoming increasingly relevant in different areas of application. A DT is generally described as a physical entity, its digital counterpart, and the two-way sharing of information between these two entities. In this way, digital twins offer an ideal approach for testing, analysing, and taking preventive action on complex systems. This new approach to system creation has been supported by the recent evolution of enabling technologies such as the Internet of Things, explainable artificial intelligence (XAI), extended reality (XR) and 5G/6G communications. However, the growing use of digital twins to solve complex problems within cyber-physical systems faces numerous challenges. Firstly, it requires an approach that integrates the different enabling technologies in a coherent manner. Furthermore, most DT development approaches are context-dependent and specifically tailored to the design of specific systems. This lack of a standard approach creates difficulties in integrating these types of systems to create complex solutions supported by the use of DT. All of this highlights the need to develop a holistic approach that can be applied to different domains, not only within the industrial sphere, but also in others such as health or social interaction, where Human Digital Twins (HDT) have recently emerged.

ETHEREAL

This project aims to create a development framework that facilitates the integration of different enabling technologies and can be applied to different domains. The different existing approaches to DT development will be analysed, proposing a unifying approach. Within this general framework, existing architectures will be studied, proposing different architectural patterns that fit different contexts. Different XAI-supported analysis and decision-making strategies will be analysed, identifying those techniques that best fit the different domains and proposing strategies for selecting the most appropriate technique in each case. Another major challenge is to integrate XR techniques that facilitate the communication of virtual counterparts to users, so an appropriate integration of this type of information representation within the development process will be proposed. Likewise, within this framework, essential aspects that offer us adequate quality assurance must be considered, providing users with truly reliable systems. Finally, the different aspects analysed above must be tested in different scenarios, for which different prototypes will be developed. These prototypes will be used to evaluate the different proposals in the development of two clearly differentiated types of DT: those that integrate humans into their interaction loop and fit the definition of HDT, and those linked to the design of cyber-physical systems.
