It is our great pleasure to invite you to the LIII International Symposium on Operational Research SYM-OP-IS 2026. The organizer of this year’s symposium is the University of Belgrade – Faculty of Transport and Traffic Engineering.

SYM-OP-IS is an international symposium that traditionally, since 1974, brings together researchers, industry representatives, and experts in the field of operational research, providing a platform for exchanging theoretical and practical knowledge through formal and informal discussions. As a venue for presenting new methods, models, and optimization techniques, the symposium fosters connections between different scientific disciplines and industrial sectors, encouraging the exchange of knowledge and experiences.

One of the key objectives of the symposium is to strengthen international cooperation by presenting the latest scientific achievements and promoting research that transcends disciplinary and national boundaries. Plenary lectures and thematic sessions offer opportunities for dynamic interaction between theory and practice, enhancing the development of operational research and its application in various fields.

We invite authors to contribute to the exchange of contemporary research in operational research—whether through methodological studies, the development of new techniques, or innovative real-world applications. Whether you explore the professional aspects of this discipline, its application in industry, or technological advancements that improve decision-making processes, your ideas and insights will enrich discussions and advance the further development of this field. The symposium is an opportunity to connect perspectives, share experiences, and collectively shape the future directions of operational research.

On behalf of the Program and Organizing Committees, we invite you to participate and contribute to the tradition and quality of this prestigious international event.
