Title: Extending SysML v2 for Safety ‐ Open‐Source Library for the System‐Theoretic Process Analysis.
Authors: Ahlbrecht, Alexander, Wagner, Florian, Durak, Umut
Source: Systems Engineering; Sep2026, Vol. 29 Issue 5, p870-884, 15p
Subject Terms: Safety, System safety, Systems engineering, Software libraries (Computer programming), Intelligent transportation systems
Abstract: Safety challenges in automated transport systems create the need for a strong design and safety coupling. In this regard, the second version of the Systems Modeling Language (SysML v2) offers new integration opportunities with extensibility features such as libraries. Due to the novelty of SysML v2, safety libraries have not yet been sufficiently explored. Hence, this article investigates the integration of the System Theoretic Process Analysis (STPA) into SysML v2. STPA was selected because of its system‐theoretic foundation and suitability for analyzing complex transport systems. Results reveal opportunities (e.g., library managers), current limitations (e.g., tool maturity), and future work (e.g., standards) for SysML v2 safety extensions. [ABSTRACT FROM AUTHOR]
