Hub location and network design at IFORS in Vienna
by Sibel Alumur Alev 22 Jan '26

22 Jan '26

Dear friends and colleagues, Stefan Nickel and I are organizing a "Hub Location and Network Design" stream at the upcoming IFORS conference, which will be held July 12-17, 2026, in Vienna. I'm pasting our stream description below. If you would like to present, you can submit your abstract using the code 7d2ac1c7 or simply by writing to me. We will then organize the talks into sessions scheduled back-to-back, so that we can all participate together. Even if you do not present in Hub Location sessions, I hope you can still join us at the next IFORS conference. For more information, please visit the conference site: https://ifors2026.at/home/ Best regards, Sibel Hub Location and Network Design Hub location and network design stream will bring together research on the strategic and tactical aspects of locating hub facilities and designing efficient networks to support transportation, logistics, and distribution systems. Contributions may include new mathematical models, solution algorithms, and empirical studies that address the selection and configuration of hub-and-spoke systems, the allocation of demand nodes to hubs, the design of interhub connections, and the integration of cost, service, sustainability, and uncertainty considerations in network design problems. Topics of interest span classical hub location formulations and multi-objective extensions, resilient and robust network designs under disruptions, multimodal and hierarchical hub configurations, and innovative optimization and heuristic methods that advance both theory and real-world applications in freight, passenger, and service networks.
