The Electronics and Telecommunications Research Institute (ETRI) has laid the foundation for more efficient use of digital twins in manufacturing sites.

ETRI announced on the 19th that it will release the 'Manufacturing Digital Twin Standard Model and Linkage Guidelines 1.0' as part of the 'Smart Manufacturing Innovation Technology Development Project' hosted by the Ministry of Science and ICT and the National IT Industry Promotion Agency.


The guidelines being released this time are aimed at maximizing the reusability of digital twin SW developed with a large investment of time and money in manufacturing sites.

It also provides guidelines for incorporating artificial intelligence (AI) technology using manufacturing site data into digital twin simulations.

The guidelines developed by ETRI suggest ways to increase reusability and minimize the burden of redevelopment through a manufacturing digital twin standard model.

In addition, while digital twins and artificial intelligence technologies have been linked in various ways so far, this guideline presents guidelines for integrating the two technologies in a consistent manner.

The contents presented in this guideline are: △Concept and structure of manufacturing digital twin standard model △Target and scope △Identification system and authority management △Composition and interface between digital twins △Creation/registration/execution of digital twins △Interoperability with related standards and Includes sample examples and use cases for linkage modeling.

ETRI also announced that its digital twin configuration technology has been approved as a follow-up standard item (NP) to ISO 23247, the world's first manufacturing digital twin international standard, which is expected to provide a green light for future international standardization efforts.

The research team is currently preparing to develop a digital twin composition standard that assembles individual digital twins like blocks to operate them as a single system in order to configure large-scale digital twins in the future four-part ISO 23247 series.

Full-scale development will begin this year, with the goal of establishing standards in 2025.

This guideline 1.0 can be viewed on the Smart Manufacturing Innovation Association website (www.smiba.or.kr).

We plan to continuously update use cases, sample codes, and templates.

In particular, we are developing use cases for application to production sites in the steel and electronics industries in cooperation with leading domestic suppliers and demand companies in the digital twin field, such as POSCO DX, LG Electronics, MI Cube Solutions, and IZPARK.

According to the research team, they plan to release the base framework SW, including development tools and execution engines in accordance with the guidelines, in the second half of next year.

ETRI Digital Convergence Research Center Director Seung-Hwan Kim said, “Through ETRI’s research activities, we will be able to significantly improve the cost and time difficulties required for small and medium-sized enterprises to build manufacturing digital twins.”
