About the Conference ISOLDE XVII will take place from June 21-25, 2026, at Loyola University in Downtown Chicago, IL. The conference, held every three years, involves scientists and practitioners, whose research interests deal with quantitative and qualitative methods for location theory, modeling and planning. All related areas of economics, engineering, geography, mathematics and operations research from both academic and business points of view are welcome to participate. Logistics Note ISOLDE conferences have been characterized by hosting the event in two different geographic locations. Based on survey feedback received from our community, we have decided to keep the conference in a single city. Many respondents indicated that cost is a major factor in their ability to attend, and hosting the second portion in a hotel would have significantly increased expenses. Despite the present uncertainties and huge financial risk involved in organizing the conference in its original form, we are still keeping up with the ISOLDE spirit by hosting the conference in two "locations" within the same city. The first and second half of the event will both be held in downtown Chicago, likely at a different facility or building. We will also provide a boat excursion in the middle of the conference. Please consider joining us and celebrate location analysis in the middle of the FIFA World Cup! We look forward to hosting you next year in Chicago!
