We are delighted to invite you to take part in the IFORS 2026 Conference, to be held in Vienna, Austria, from July 12 to 17, 2026.
The International Federation of Operational Research Societies (IFORS; https://www.ifors.org) is a 60-year-old organization with currently 50 national member societies. One of its core activities is the IFORS Triennial Conferences (https://www.ifors.org/ifors-triennial-conferences).
The Program Committee, chaired by Andrés L. Medaglia (Universidad de los Andes, Colombia); and the Organizing Committee, led by Karl F. Doerner, Jan F. Ehmke and Richard F. Hartl (University of Vienna, Austria), are working closely together to create an unforgettable scientific experience.
The 24th IFORS conference offers the global Operational Research community an excellent opportunity to reunite in a vibrant city. Vienna's location in the heart of Europe, its excellent infrastructure, short distances, and exceptional quality of life are just some of the city's many strengths. In addition, Vienna impresses with its high standards of hospitality and an outstanding range of art and cultural events.
The University of Vienna, located in the city center and host of IFORS 2026, is the oldest university in the German-speaking world and the largest university in Austria. As a “universitas litterarum”, it offers a broad range of subjects that promotes the development of innovative research areas and strengthens close connections between research fields.
We warmly welcome and encourage researchers, academics, practitioners, and students involved in Operational Research and related fields to submit their abstracts for review and contribute to this unique event!
