Final MasCot Program Day Highlights Results, Lessons Learned, and Future Collaborations

Posted on by bennyakesson

I had a fantastic time hosting the fourth Mastering Complexity (MasCot) Program Day on October 9 at TU Delft. MasCot, a €3M academic program co-funded by TNO-ESI and NWO, addresses the pressing need for new advanced engineering methodologies through four projects covering essential topics, such as design space exploration during early system design, scheduling, verification, and restructuring of evolving software.

The day started with an update from the four academic projects in the program, focusing on updates and new results from the last year. It was interesting to hear a mix of positive results, e.g. new scheduling methods that outperform previous approaches, as well as negative results, a counter-example that demonstrated that further attempts at proving a particular theory were not worthwhile.

In the afternoon, TNO-ESI and industry partners from the projects shared their user stories, in which they reflected on the value of the program and the knowledge and proof-of-concept implementations developed in it. The user stories were positive and included examples of planned and ongoing technology transfer from the projects.

There were also breakout sessions where TNO-ESI, academic staff, industry representatives, and PhD students separately discussed what went well during the organization and execution of the program, and what should be done differently in the future. This feedback will be consolidated in a document describing the lessons learned from the MasCot Program, which will be used as a basis to refining the method for academic collaborations at TNO-ESI. It was clear from the feedback from all groups that everyone appreciated the program and how TNO-ESI brought academia and industry together to solve relevant problems. A main challenge for the future is to better align stakeholders from industry and academia and their different goals, environments, and timelines.

The day program was concluded with an interactive session, structured around our PMCs, where participants worked together to identify interesting research challenges and hot research topics for future academic collaborations. What stood out in terms of challenges was a clear need to address testing and integration challenges, also in the context of microservices. When looking at hot research topics and technological opportunities … you guessed it … safe, explainable, responsible, … , AI for Systems Engineering!

The day concluded with a social program at Stadsbrouwerij De Koperen Kat with a short tour given by the owner and a BBQ buffet with beer tasting. That concluded the fourth, and last MasCot Program Day.

 

TNO-ESI and Academic Partners Deliver ASCI PhD Course on Design and Implementation of Real-time Systems

Posted on by bennyakesson

The Netherlands boasts a world-leading high-tech manufacturing industry renowned for constructing distributed real-time systems of continuously growing complexity. These systems must meet stringent timing requirements to ensure the delivery of mission-critical functionalities. To create interest in the high-tech equipment domain and prepare PhD students in Computer Science to address its performance challenges, TNO-ESI has co-created and delivered a one-week PhD course Design and Implementation of Real-time Systems together with academic partners from Eindhoven University of Technology, University of Twente, and University of Amsterdam. The course is given in the context of the Advanced School for Computing and Imaging (ASCI), a Dutch research school for high-quality research and education in computer systems and imaging systems. ASCI encompasses almost all Dutch universities with computer-science departments. The main goals of ESI involvement in this course were to make participants aware of TNO and its role in society and industry and position it as a possible future employer, and creating awareness of TNO-ESIs vision and work in the area of system performance engineering.

The course is focused on providing an overview of selected timing-sensitive applications and the current research landscape on real-time systems and explaining the rationale behind considering real-time requirements in system software design. Through a series of lectures and hands-on labs, the course covers selected topics from scheduling algorithms, priority assignments, resource sharing, resource reservation, together with their implementation in real-time operating systems. It further discusses emerging challenges and practices in an industrial context, based on empirical surveys and experience from TNO-ESIs applied research on telemetry-based system performance engineering for purposes of performance optimization, verification, and diagnostics.

This first instance of the course was given at the Carlton President Hotel in Maarsen, outside Utrecht between June 10 – 14. 15 PhD students from universities all over the Netherlands researching a broad range of topics in computer science participated in the course. TNO-ESI was in the spotlight during the last day of the course. In the morning, I introduced the high-tech equipment domain and its complexity drivers and explained how new model-based engineering methodologies where needed to address them. Next, my colleague Bram van der Sanden presented our view on the field of System Performance Engineering, along with its focus areas and best practices. This was followed by two concrete examples from our system performance research: Kostas Triantafyllidis presented his work on performance analysis and diagnosis with ASML, followed by a presentation by me about performance verification and conformance checking in microservice systems based on our work with Thales.

The course was well-received by the participants and the contents were rated 8.7/10 in the evaluation. We very much enjoyed the experience of creating and delivering this course together with our academic partners. Thank you Kuan-Hsun Chen (leader of the initiative), Mitra Nasri, and Geoffrey Nelissen for the excellent collaboration in organizing this course. Thanks to Kay Heider and Christian Hakert for leading the hands-on exercises. We are also thankful to invited speakers Bram van der Sanden and Kostas Triantafyllidis.

Mastering Complexity at ICT.Open

Posted on by bennyakesson

This week saw another edition of NWO ICT.OPEN, a yearly event that brings scientists from all ICT research disciplines and industries together to learn, share ideas, and network.

My colleague Rosilde Corvino and I from TNO-ESI chaired the Mastering Complexity for Cyber-Physical Systems track. This track was kicked off with a keynote about software architecture for strategic advantage, given by Erik Schepers, Chief Software Architect at Thales. Two presentations followed about using large language models to manage software legacy and task-oriented programming for the Internet of Things, respectively. Approximately 30 participants attended the track, highlighting its relevance and the keen interest in cyber-physical systems. The event also saw a few projects from ESI’s Mastering Complexity (MasCot) academic program, DSE2.0 and Software Restructuring, being present with posters.

Lastly, the poster “Models for Legacy Software Systems,” authored by ESI colleagues Joe Reynolds, Nan Yang, Rosilde Corvino, Anca-Maria Lichiardopol, and Joost van Zwam, won the best poster award at the ICT.Open conference. The work has been prized for its innovation, applicability, and clarity of presentation. Congratulations to the team for this achievement, and kudos to Joe Reynolds for his outstanding presentation, demo, and poster explanation.

Next Tuesday, it is time for the next event, the crown jewel of ESI, the ESI Symposium 2024. It is still possible to register for free. I hope to see you there!

Keynote on Managing Variability and Evolution in High-tech Equipment at FOSD Meeting 2024

Posted on by bennyakesson

I had the distinct honor of opening this year’s Meeting on Feature-Oriented Software Development (FOSD Meeting) with a keynote titled “Managing Variability and Evolution in High-tech Equipment”. FOSD Meeting is a yearly informal meeting to bring together the community of researchers working on feature-oriented software development. This year, the event was hosted by TU/e between April 9 – 12.

The keynote covered complexity trends in the high-tech equipment domain, ESI and its role in the high-tech innovation eco-system, and two examples of how variability and evolution were tackled using model-based methodologies at the level of the software architecture in our projects with Thales. The keynote was appreciated by the organizers of the event and the group of 35 participants, mostly from (German) universities but also from ESI’s international applied research partner DLR.

Reflecting on my experience, I was pleasantly surprised at the broad expertise in this community, which covered modelling, software engineering, and performance and I wished I could have stayed around to enjoy the rest of the event. I am happy to see that the keynote triggered some concrete follow ups that can help us link members of this academic community to research in the high-tech equipment ecosystem.

Inaugural Lecture Explores Managing Complexity of High-Tech Systems

Posted on by bennyakesson

Today, I finally gave my inaugural lecture “Managing Complexity in High-tech Systems” to celebrate my appointment as Endowed Professor at the University of Amsterdam, which happened back in 2019.

The academic ceremony started at 16:00 with a small reception for fellow professors and members of the curatorium. Together, this group walked in a procession into the beautiful auditorium of the University of Amsterdam, where an audience of colleagues, family, and friends, where waiting in anticipation. The lecture discussed the challenge of increasing complexity in the high-tech equipment industry and how new (model-based) development methodologies leveraging abstraction, boundedness, and composition, are required to address it. I argued that the required innovation should come from collaboration in an innovation chain, where universities, applied research organizations, and industry work together in strategic partnerships. The presentation was concluded with a number of concrete examples of what this collaboration could look like, based on examples from my education and research at TNO and the University of Amsterdam. The inaugural lecture was followed by a reception full of networking and congratulations. I would like to thank everybody that showed up for the event, physically and online. Together, we created a memory that I will treasure for a lifetime.
