b'In this episode Professor Graham Currie meets with Professor Stefan Vo\\xdf, who is Director of the Institute of Information Systems and (until the end of 2022 was) the Dean of the Hamburg Business School at the University of Hamburg. Stefan has a background in mathematics, computer science and related fields. He and Graham discuss this and the fields of operations and information management, including the application of artificial intelligence and heuristics to public transport and other scheduling problems. Stefan outlines research he has done on timetable synchronisation (sometimes referred to as timetable coordination). Much of this has been in partnership with industry, and Stefan and Graham briefly discuss some of the challenges of publishing research within the constraints of commercial confidentiality. \\n\\nRobustness in transport systems is another of Stefan\\u2019s other areas of research interest. He outlines work he has done on the Hamburg public transport system looking at predicting service delays and developing a mathematical formulation of robustness.\\n\\nStefan was also an co-author on A Scientometric Analysis of Public Transport Research, published in the Journal of Public Transportation (DOI: http://doi.org/10.5038/2375-0901.18.2.8, available at: https://digitalcommons.usf.edu/jpt/vol18/iss2/8). This paper undertook a broad review of the Public Transport research, looking at key authors, journals and other aspects of the field. Graham and Stefan discuss the use of Impact Factors in assessing the importance of research outputs, and Stefan highlights how the scientometric analysis findings might suggest that the current emphasis on Impact Factor may not provide a full picture of which publications are particularly important to the field. \\n\\nMoving on to discuss upcoming research, Stefan talks about his current work using digital twins to better understand power usage at container terminals. Graham and Stefan briefly discuss how similar issues of power supply may be turning out to be a problem for public transport depots that need to provide electric bus recharging. Stefan also talks about how digital twins might support research into, and the management of, public transport networks. \\n\\nFind out more about Stefan and his work at: \\nhis profile page at the University of Hamburg at https://www.bwl.uni-hamburg.de/en/iwi/team/mitglieder/stefan-voss.html \\nhis publications at World Transit Research at https://www.worldtransitresearch.info/do/search/?q=author%3A(%20stefan%20vo%C3%9F%20)&start=0&context=1060035&sort=score&facet= \\nhis ORCID page at https://orcid.org/0000-0003-1296-4221 \\n\\n\\nHave feedback?
