    Episode 21 (English) - STPA in practice and SAE J3187 - with Mark A. Vernacchia

    Mark A. Vernacchia is a GM Technical Fellow and is the Principal System Safety Engineer for all GM propulsion systems worldwide. Mark received a BS in Mechanical Engineering from Purdue University and an MS in Engineering Sciences from Rensselaer Polytechnic Institute (RPI). He has been listed on 24 control system based patents as an inventor. Mark is a Professional Engineer in the State of Michigan and is recognized as an Expert Systems Engineering Professional (ESEP) by the International Council of Systems Engineers (INCOSE). In this episode, Mark talked about SAE J3187, a recommended practice for evaluations of automotive related safety-critical systems using the system-theoretic process analysis STPA. Goal of this document is to provide both educational materials and lessons-learned gained by STPA practitioners. Further, Mark talked about his experiences using STPA and being a task force leader developing the recommened practice. There will be a major update of SAE J3187 in the first quarter of 2023.

    Episode 19 (English) - STAMP and STPA - A systems approach for complex systems - with Michael Schmid

    Michael Schmid is a Technology Architect and Loss Prevention Specialist in the field of autonomous systems. His research focuses on preventing losses related to the use of Artificial Intelligence (AI) and making AI safe for use in everyday technology. Previously, Michael has worked on automation features in cars, self-driving software, and has developed a certification approach for automated vehicles. Michael has a Master‘s degree from the Massachusetts Institute of Technology (MIT) and is currently a PhD candidate in the Group for System Safety and Cybersecurity at MIT. He is the second time guest in this podcast. In this episode, Michael gave a thorough introduction to STAMP and STPA. STAMP is an accident causality model that was developed by prof. Nancy Leveson at MIT. It is based on systems theory and systems thinking. It is well-suited to addresses the challenges in engineering when working with critical complex systems. STPA is an analysis method based on STAMP to analyze systems to proactively avoid accidents. In comparison, CAST is the a method to analyse accidents that already happened.

    Episode 18 (German) - Einfluss von 5G auf die Avionik von Flugzeugen - mit Holger Flühr

    Dr. Holger Flühr ist seit 2003 an der FH Joanneum tätig und seit 2006 ist er dort Professor für Avionik und Flugsicherungstechnik. Zudem agierte er zeitweise auch als Instituts- und Studiengangsleiter. Davor war nach jahrelanger Tätigkeit in der Forschung im Forschungszentrum Karlsruhe (aufgegangen im KIT) und der TU Graz eine Zeit lang auch bei einem Unternehmen beschäftigt, das sich mit der Entwicklung von Hochfrequenz-Bauteilen für Mobilfunkanwendungen beschäftigt. Abschließend wären noch die Mitgliedschaften in Beratungsgremien und Interessensvertretungen zu erwähnen. In den letzten Wochen war in Zeitungen und Online-Medien vermehrt über den Mobilfunkstandard 5G und mögliche Komplikationen mit Flugzeugen zu lesen. Kurz gesagt besteht die Gefahr, dass die 5G-Mobilfunkwellen Flugzeuge während der Landung stören könnten. Und während die Luftfahrt grundsätzlich als sehr sicher gilt, gehören Start und eben auch Landung zu den kritischeren Phasen eines Flugs. Was hat es nun mit den Berichten auf sich? Auf diese und weitere Fragen ist Herr Flühr im Podcast eingegangen. Am Anfang wurde vor allem das geklärt was die Avionik überhaupt ist und anhand welcher Grundidee man Flugzeuge und deren Systeme sicher gestaltet.

    Episode 17 (English) - Verification and standardization of autonomous vehicles - with Siddartha Khastgir

    Dr Siddartha Khastgir is the Head of Verification & Validation of collaborative autonomous vehicles (CAV) at WMG, University of Warwick, UK. His research areas in the CAV domain include test scenario generation, safety, simulation-based testing, Safe AI among many others. He has received numerous national and international awards for his research contributions, including the prestigious UKRI Future Leaders Fellowship, a seven-year Fellowship focused on safety evaluation of CAVs, and is a Forbes 30 Under 30 Europe list maker. He is also the project leader for ASAM standardisation project - OpenODD, and an active participant at ASAM, SAE, ISO and UNECE discussions. In this episode we talked about verification and validation of autonomous vehicles. This includes the advantages and challenges of simulations and how one research question raises several more questions. We also talked about the low-speed autonomous driving and about the new standard ISO 22737 “Low-Speed Automated Driving (LSAD) systems”. He was the lead author of that standard, as well as of ISO 34503 “Taxonomy for ODD”, where ODD stands for Operational design domain.

    Episode 16 (English) - Systems approach to Safety - with Michael Schmid

    Michael Schmid is a Technology Architect and Loss Prevention Specialist in the field of autonomous systems. His research focuses on preventing losses related to the use of Artificial Intelligence (AI) and making AI safe for use in everyday technology. Previously, Michael has worked on automation features in cars, self-driving software, and has developed a certification approach for automated vehicles. Michael has a Master‘s degree from the Massachusetts Institute of Technology (MIT) and is currently a PhD candidate in the Group for System Safety and Cybersecurity at MIT. In this episode, Michael provided some insights into his research and explained why we need a systems approach to solve many of today‘s problems in technology. As an example, Michael and I discussed some of the challenges of autonomous cars and he outlined a systems-based approach for their certification. Michael provided a quick overview of his current research, making AI-based technology safe, and described some of his main ideas. STAMP, a new accident causality model developed by Nancy Leveson, Michael‘s supervisor at MIT, serves as the basis for his approach.
