From PPR to Interoperability: A Lightweight Engineering Modeler Bridging SysML v2 and AutomationML

Model-based engineering approaches such as SysML v2 and AutomationML address overlapping challenges in the engineering of production systems, yet they originate from different communities, modeling traditions, and tool ecosystems. Directly mapping complete standards can therefore become technically complex while still leaving a substantial barrier for practitioners.

This contribution explores Product–Process–Resource (PPR) modeling as a deliberately small semantic intersection between both ecosystems. Based on this idea, a lightweight web-based PPR engineering modeler was developed. The tool enables engineers to define products, processes, and resources, instantiate them within production-system models, describe their properties, and connect them through explicit engineering relationships such as product inputs and outputs or resource–process assignments. A graphical modeling environment provides an accessible view of the resulting production structure.

Internally, the application uses a typed Pydantic-based semantic model inspired by selected SysML v2 concepts, including definitions, usages, items, parts, and actions. This canonical model separates the domain-specific PPR modeling surface from its technological representations and provides a basis for transformation toward SysML v2 and AutomationML.

Rather than proposing another general-purpose modeling language, the approach investigates how a constrained and recognizable PPR modeling environment can act as a technical and sociotechnical handshake between engineering communities. The prototype demonstrates how lightweight tooling, explicit semantics, and standard-oriented mappings can lower the entry barrier to cross-domain model interoperability.
