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.

Last week, the International Conference on Emerging Technologies and Factory Automation (ETFA) took place in Sinaia, Romania. The LIT CPS Lab was represented by a 13-member team at the conference, 7 of them CD Lab members. The list of all presented CD Lab papers can be found on our publication page.
What is it like to attend a conference for the first time?
"At the conference, I gave a presentation on possible scenarios that can lead to the Shotgun Surgery bad smell and possible ways to find it. I also presented a poster on this topic," Dunja Zivotin explains. "My initial nervousness quickly disappeared when I noticed the great support in the team. This gave me the necessary confidence and self-assurance to deliver the presentation successfully," the young scientist reports on how she experienced her first conference visit.
What is it like to have attended ETFA for more than the 10th time?
"Every year, ETFA provides a platform for exchange with international researchers. I meet many of the colleagues only once a year at this conference - in personal conversations, for example, new collaboration opportunities or interesting research questions arise. I also enjoy connecting our team members with other researchers," Professor Zoitl says.
How was the overall experience?
"I am very proud of the team. Our team's presentations and posters - in fact, from all 11 presenters - were all excellent and among the best at the conference. The feedback was positive throughout," says Professor Rabiser, excited about his team's successes.
Sayyid, Kevin and Rick presented work from the CD Lab VaSiCS at the 27th ACM International Systems and Software Product Line Conference (SPLC 2023) in Tokyo, partly there, partly online.
Sayyid presented Managing Cyber-Physical Production Systems Variability using V4rdiac: Industrial Experiences, an industry full paper which summarizes our experiences with CPPS variability in industry and wrt applying the V4rdiac approach developed in the CD lab to deal with CPPS variability in industry.
Kevin presented the UVL Parser (UVLParser: Extending UVL with Language Levels and Conversion Strategies), a tool which facilitates working with the community-developed Universal Variability Language.
Rick presented results of the SPLC 2023 Industry Variability Challenges Workshop, in which challenges of industry with variability and software product lines were collected.
Another great success for the CD Lab. After 9 full papers which have already been accepted, 9 further work-in-progress papers have now been accepted at the ETFA 2023 Conference. We congratulate all authors!
