Operations Research - doctoral student represents RTG at international conferences

RTG doctoral student Julia Erdmann (subproject H1) was represented at two important international conferences in the field of Operations Research this summer: EURO 2025 in Leeds (UK) (22. - 25.06.2025) and OR 2025 in Bielefeld (02. - 05.09.2025).

EURO 2025 - 34th European Conference on Operational Research

EURO 2025 was hosted at the University of Leeds and also marked the 50th anniversary of the EURO conference series. The special atmosphere was palpable: an international audience, diverse presentations and a lively discussion about the future of operations research. With participants from all over Europe and beyond, new methods, optimization approaches and applications were presented.

As part of this conference, Julia Erdmann gave a presentation on her research topic "A European-Wide Multi-Objective Hydrogen Supply Chain Model Considering Sector-Specific Decarbonization Potentials". In this paper, an optimization model was presented that maps a Europe-wide hydrogen supply chain, taking into account the emission reduction potential in various sectors in particular. The aim of the work is to make the trade-offs between costs and emission reduction transparent and to identify European regions and sectors that should be prioritized in the implementation of decarbonization strategies.

OR 2025 - International Conference on Operations Research

OR 2025 followed just a few weeks later at Bielefeld University. Under the motto "Quantitative Approaches for a Complex World", the conference brought together over 400 researchers from academia and practice. The spectrum of topics presented ranged from energy and climate issues to logistics and sustainable resource strategies.

Here, too, Julia Erdmann presented another research paper with her presentation: "Optimizing Biomass Collection under Uncertain Quality: A Stochastic Routing Approach with Decentralized Adaptability". In this work, a modeling approach was developed that addresses the challenges of varying biomass quality in bioenergy production and at the same time enables flexible operational decision adjustments during collection.

Participation in both conferences offered the opportunity to present current research results to an international audience of experts and at the same time to gain valuable impulses from other disciplines and application areas. In addition to the scientific sessions, there were numerous opportunities to network with colleagues from all over the world. It was this personal exchange that made the days in Leeds and Bielefeld a particularly enriching experience.
