This guidebook, published by domestic researchers, outlines the use of "digital twin" technology, which is considered a key technology for the Fourth Industrial Revolution, and leads the way in the use and expansion of digital twins.

The Electronics and Telecommunications Research Institute (ETRI) announced on the 17th that it has published a revised edition of “Dream of Digital Twin,” which presents ways to utilize digital twin technology in various industrial and public sectors. It also reported that it proposed the world's first international standard related to 'digital twins' to the International Organization for Standardization (ISO), completed development as ISO 23247 in October of last year, and published and distributed it.

Digital twin technology can be used to discover and solve real-world problems through simulations in virtual space, and is applied not only in industries such as manufacturing and energy, but also in public sectors such as the environment, disaster relief, and cities.

ETRI's recently revised and published "Dream of Digital Twins" provides a blueprint for technology demanders on how digital twins can be utilized to solve industrial and social problems in various fields.

This report supplements the existing digital twin data modeling, linkage and interface between different digital twins, fidelity of representation and visualization, fidelity design criteria, and level maturity diagnosis model.

△Research results on linkages with other related technologies such as AR, VR, MR, CPS, and metaverse △Concept and definition of digital twins, expected effects △Types of digital twins and model combinations △Interoperability △Life cycle management and digital thread △Reference models and modeling methods have been added.

Current digital twin technology development often presents challenges due to insufficient understanding of digital twins, time, cost, and personnel shortages. The report emphasizes the importance of prior consideration of the concept and understanding of digital twins, along with appropriate investment tailored to industry characteristics. This approach is expected to serve as a solution to address root causes.

The research team also achieved results in the international standardization of digital twin technology. In 2018, the first international standard related to digital twins was proposed, and in October of last year, the development of the ISO 23247 series of standards (a standard document defining the framework technology for applying digital twins to the manufacturing sector) was completed.

The research team added that they are also preparing to develop standards for digital threads (Part 5) and digital twin composition (Part 6), with a target date of 2025.

Kang Shin-gak, Director of ETRI's Standards Research Division, stated, "Digital twins are a key technology in the digital transformation era, enabling intuitive solutions to real-world problems in a virtual space. We hope this report and standards will serve as a guide for researchers, businesses in various industries seeking to utilize the technology, and users."
