A Review of Asset Administration Shell

Industry 4.0 needs to dynamically adjust complex production lines made up of various assets. Asset Administration Shell (AAS) is a virtual representation of the assets of the Industry 4.0 era. It forms the industrial components under Industry 4.0 with the physical parts of the assets. This paper combs the research progress and challenges of AAS from 2016 with the theme of interoperability, modelling, and application, and looks forward to possible future research directions.
