Present at IFORS CHILE 2023

Between July 10 and 14, our country hosted the 23rd version of the IFORS (International Federation of Operational Research Societies) world conference and in this event that brought together more than 1,000 researchers and students dedicated to Operations Research (OR), our Operations group could not be missing. Thus, during the week that this congress lasted, hosted at the University of Chile and the Pontificia Universidad Católica and organized by the Chilean Institute of Operations Research (ICHIO) and the Institute of Complex Engineering Systems (ISCI) -the latter housed in our department-, several professors and students from our department gave talks presenting their work on OR.

Here is the record of our participation in the conference program:
