Feature Model for Compliance

The transition from the EU Machinery Directive (2006/42/EC) to the upcoming Machinery Regulation (EU 2023/1230), alongside the revision of ISO 12100, introduces new cybersecurity obligations integrated with established safety requirements for industrial pumps [1]–[4]. These changes necessitate faster and more systematic compliance processes than current document-heavy manual practices can support [5], particularly for manufacturers managing multiple product variants, such as connected and non-connected pumps. This thesis explores feature modeling, a technique from product-line engineering, to represent and manage evolving regulatory requirements. A comprehensive feature model was manually extracted from the Machinery Directive, the Machinery Regulation, and both editions of ISO 12100, and implemented using FeatureIDE [6]. The model organizes the safety, cybersecurity and documentation clauses into a hierarchical compliance map, enriched with cross-tree constraints to capture critical interdependencies, such as not secure → not safe. The results indicate that feature modeling reduces oversight risk, enables detection of regulatory changes, and provides a foundation for automating evidence generation. Although the proof-of-concept focuses on pump manufacturing, the approach is generalizable to other domains with complex, multiconcern, and rapidly evolving compliance requirements.
