Project Result: Submodel Proposal for Rule-Based AAS Behavior

The Proac­tive Asset Admin­is­tra­tion Shell project exam­ined how Asset Admin­is­tra­tion Shells (AAS) can be extended beyond static data exchange to include explic­itly modeled behavior. While AAS are commonly used to struc­ture and share asset infor­ma­tion, logic such as vali­da­tion, event trig­gering, or oper­a­tional handling is usually imple­mented outside the model in appli­ca­tion code.

The project addressed this limi­ta­tion by inves­ti­gating rule-based approaches for describing AAS behavior in a trans­parent and reusable way. The work focused on how declar­a­tive, machine-read­able rules can be linked to AAS elements in order to vali­date prop­erty changes, trigger events and oper­a­tions, and imple­ment internal update logic across prop­er­ties and submodels.

Based on these inves­ti­ga­tions and prac­tical eval­u­a­tions, the project resulted in a submodel proposal that consol­i­dates the devel­oped concepts into a struc­tured, cross-domain model. The proposal defines stan­dard­ized, executable rules for AAS behavior and is currently under review.
