Developing And Piloting A Procedure For Systematically Deriving The Digital Twin Based On The Asset Administration Shell

The H2Giga-FRHY research project aims to investigate the high-rate production of electrolysers. In this context, an enabling IT infrastructure and software services will be implemented. A central enabling technology in this context is the digital twin based on the asset administration shell. Overall, there are still very different concepts of the digital twin in academia and industry, and in addition there is often a lack of direction in its implementation and application. The concept of the asset administration shell also needs further elaboration in its conceptualisation and implementation to support practitioners. This paper presents a procedure for deriving the digital twin based on the asset administration shell. The applied approach builds up on previous research, which is consolidated and detailed in this work. It includes the use case-specific and requirements-based modelling, gap analysis and the development of the asset administration shell data model. By enabling a software service for product evaluation, the approach is being tested in the H2Giga FRHY research project. The service intended to facilitate data-driven product development by providing the user with information and hints for possible product improvements, thus supporting in the decision making process while keeping the user in charge.
