Welcome

Welcome to The International Conference on Operations Research 2025 (OR 2025)

Quantitative approaches for a complex world

The International Conference on Operations Research, the annual conference of the German Operations Research Society (GOR), looks forward to welcoming you to Bielefeld, Germany.

The OR 2025 is an opportunity for academics, researchers and practitioners to discuss methods and applications of Operations Research, management science, data science and analytics. How can quantitative methods help to find solutions to problems in a closely networked world? This often requires interdisciplinary approaches typical of Operations Research applications.

The conference will take place from September 2-5, 2025 at Bielefeld University. We invite academics, researchers and practitioners from all over the world to participate in this inspiring OR 2025 conference and to submit an abstract and optionally a paper for the proceedings.

We look forward to seeing you in Bielefeld!
