Welcome to the Christian Doppler Laboratory for Mastering Variability in Software-Intensive Cyber-Physical Production Systems (CDL VaSiCS)
The CD Lab aims to conduct applied, basic research focusing on methodological support to master variability in Software-Intensive Cyber-Physical Production Systems (CPPS). A key focus lies in automatically handling variability, such as analyzing existing CPPS artifacts from the design process of CPPS to automatically extract and model variability information and generating and configuring target artifacts, especially to better support system evolution and future changes in software and hardware platforms as well as tools.

Dr. Sayyid
Today, Sayyid (Hafiyyan Sayyid Fadhlillah, https://scholar.google.com/citations?user=Ae-cMfcAAAAJ&hl=en) very successfully defended his PhD thesis "A Multidisciplinary Variability Management Approach for Control Software in Cyber-Physical Production Systems", a core result of the CD Lab VaSiCS. The thesis was supervised by Rick Rabiser and Alois Zoitl. We want to thank the defense committee, especially external reviewer Thomas Thüm, but also Manuel Wimmer and Josef Küng as head of committee!
We look back at 4 years of excellent research work done by Sayyid. Also, Sayyid is just the best team member and colleague one could wish for. Always helpful and motivated. While we wish him all the best for his post-doc at another university, we will miss Sayyid a lot! Please always stay in touch and keep collaborating with us!

SE 2025 in Karlsruhe
Five members from the LIT CPS Lab and 4 from the CD lab VaSiCS attended the Software Engineering Conference at the Karlsruhe Institute of Technology between Feb 24 - 28, 2025. In addition to expanding on contacts and networking, Rick Rabiser gave a keynote speech at the SECPPS Workshop focusing on Software Engineering in Cyber-Physical Systems: A Story of Variability and Complexity. He also presented a paper by Martin Becker, Rick Rabiser, Goetz Botterweck titled: Not Quite There Yet: Remaining Challenges in Systems and Software Product Line Engineering as Perceived by Industry Practitioners. Lisa Sonnleithner served as one of the workshop chairs.

Congratulations, Philipp!
Philipp Bauer successfully defended his Master's thesis "Supporting Control Software Evolution with Model Comparison" (supervised by Lisa Sonnleithner and Rick Rabiser) on February 4. The thesis focuses on extracting differences and equivalences between variants and converting them into delta artifacts and integrating them into Eclipse 4diac™, providing a visualization tool and the semi-automatic generation of delta artifacts given any number of variants. Furthermore, the thesis evaluates the effectiveness of the proposed methods by means of quantitative comparisons and qualitative analyses, addressing research questions about algorithm performance, delta generation strategies, and manual effort reduction.
Congratulations on defending your thesis and attaining the highest possible grade! We wish you all the best in the future and thank you for your impressive efforts!
Thank you, too, Birgit Pröll and Alois Zoitl, for serving as part of the Master's thesis defense committee!

Two Papers Accepted in a Highly-Ranked JSS Journal
A lovely surprise just before the winter holidays: Two articles featuring #litCPSlab #CDLVaSiCS co-authors have been accepted in the Journal of Systems and Software 😍, the currently third-highest ranked publication venue in the field of software systems according to Google Scholar.
Titled "Hafiyyan Sayyid Fadhlillah, Kristof Meixner, Sandra Greiner, Antonio Manuel Gutiérrez Fernández, Rick Rabiser: Managing Control Software Variability in Cyber-Physical Production Systems: The V4rdiac Approach", the article focuses on the core theme of Sayyid's PhD dissertation, the V4rdiac Approach, a delta-oriented, multidisciplinary variability management approach to manage cyber-physical production system control software variants.
Titled "David Benavides, Chico Sundermann, Kevin Feichtinger, José A. Galindo, Rick Rabiser, Thomas Thüm: UVL: Feature Modelling with the Universal Variability Language", this paper focuses on the outcome of a community-driven effort to develop a variability modeling language: the Universal Variability Language (UVL). We envision UVL as a pivotal solution, addressing the limitations of prior attempts and fostering collaboration and innovation in the domain of software product line engineering.
The links to both papers will be available here shortly.
Congratulations to all of the authors, Happy Holidays, and a Happy New Year!
