Following the success of previous EURO Conferences, we announce the XXVI EURO - INFORMS Joint International Conference: "All roads lead to OR" which will be held in Rome on July 1-4, 2013 (get-together evening and welcome reception on Sunday, June 30th at Sapienza University of Rome). The Programme Committee chaired by Marc Sevaux (EURO) and David Simchi Levi (INFORMS) and the Organizing Committee chaired by Paolo Dell'Olmo (AIRO), are preparing a high quality scientific programme and an exciting social programme for the conference. We are sure that the XXVI EURO - INFORMS Joint International Conference will be an extraordinary opportunity for the OR community to get together again in a unique location, and we are looking forward to meeting you in Rome in 2013.
