From Capability Models to Automated Planning: An AAS-Native Approach for Automatic PDDL Generation
Summary
An AAS-native approach has been developed to automatically generate Planning Domain Definition Language (PDDL) problems from Asset Administration Shell (AAS) capability models. This method enables production engineers to verify production system layouts and required sequences without specialized PDDL expertise. The capability models are structured using four established Industry 4.0 standards: VDI 3682 for process descriptions, IEC 61360-1 for semantic property qualification, IDTA 02011 for type hierarchies, and IDTA 02016 for instance descriptions. Unlike previous methods, this approach derives all planning elements from domain-level descriptions of resource functions, called capabilities, eliminating the need for engineers to interact with PDDL syntax. An extraction algorithm transforms distributed Multi-AAS architectures into complete PDDL planning problems. The approach was validated on AAS models of a laboratory production system, comparing four layout variants to demonstrate systematic exploration of design trade-offs.
Key takeaway
For production engineers verifying system layouts or designing industrial assets, this AAS-native approach significantly simplifies automated planning. You can now model resource capabilities using established Industry 4.0 standards without needing specialized PDDL expertise. This enables you to systematically explore design trade-offs by modifying AAS models and automatically regenerating planning domains, accelerating verification cycles and optimizing production sequences. Consider integrating AAS capability modeling into your design workflow to streamline planning.
