Behavior Trees for Robotic Systems: An Empirical Study on Practices and Experiences
Razan Ghzouli, Jennifer Horkoff, Daniel Strüber +1
Over the last decade, behavior trees (BT) have become one of the dominant behavior models for coordinating missions of robotic systems. Yet empirical evidence on BT adoption in rea…
Leveraging Large Language Models for Cybersecurity Risk Assessment -- A Case from Forestry Cyber-Physical Systems
Fikret Mert Gultekin, Oscar Lilja, Ranim Khojah +3
In safety-critical software systems, cybersecurity activities become essential, with risk assessment being one of the most critical. In many software teams, cybersecurity experts a…
Using Behavior Trees in Risk Assessment
Razan Ghzouli, Atieh Hanna, Endre Erös +1
Cyber-physical production systems increasingly involve collaborative robotic missions, requiring more demand for robust and safe missions. Industries rely on risk assessments to id…
Extending Behavior Trees for Robotic Missions with Quality Requirements
Razan Ghzouli, Rebekka Wohlrab, Jennifer Horkoff

Towards a Value-Complemented Framework for Enabling Human Monitoring in Cyber-Physical Systems
Zoe Pfister, Michael Vierhauser, Rebekka Wohlrab +1
[Context and Motivation]: Cyber-Physical Systems (CPS) have become relevant in a wide variety of different domains, integrating hardware and software, often operating in an emergin…
Human Factors in Model-Driven Engineering: Future Research Goals and Initiatives for MDE
Grischa Liebel, Jil Klünder, Regina Hebig +23
Purpose: Software modelling and Model-Driven Engineering (MDE) is traditionally studied from a technical perspective. However, one of the core motivations behind the use of softwar…
Guidelines for Artifacts to Support Industry-Relevant Research on Self-Adaptation
Danny Weyns, Ilias Gerostathopoulos, Barbora Buhnova +16
Artifacts support evaluating new research results and help comparing them with the state of the art in a field of interest. Over the past years, several artifacts have been introdu…
Managing Traceability Information Models: Not such a simple task after all?
Salome Maro, Jan-Philipp Steghöfer, Eric Knauss +7
Practitioners are poorly supported by the scientific literature when managing traceability information models (TIMs), which capture the structure and semantics of trace links. In p…
Defining Utility Functions for Multi-Stakeholder Self-Adaptive Systems
Rebekka Wohlrab, David Garlan
[Context and motivation:] For realistic self-adaptive systems, multiple quality attributes need to be considered and traded off against each other. These quality attributes are com…
