This year, the ANT/OR group organises the ORBEL conference. ORBEL29 is the 29th conference on Operations Research (OR), reuniting the Belgian research community on OR-related topics. ORBEL29 is about exchanging ideas and insights, by stimulating interaction and discussion. The host institution of this year's conference is the University of Antwerp. This vivid city is located on the banks of the River Scheldt, and home to one of the largest seaports in the world. The name Antwerp is synonymous with diamonds, culture, art, Rubens and fashion.
