Bethlehem, Pennsylvania, USA (August 15, 2013) – The winner of the 2013 AIMMS-MOPTA Competition has been named as Team ORopt from the Technische Universität in Berlin and ZIB. The announcement was made tonight at the MOPTA Conference dinner hosted at Lehigh University in Pennsylvania. The sole member of the winning team is Alexander Tesch (ZIB, TU-Berlin), who was advised by Ralf Borndörfer (ZIB).

Operation Room Management Under Uncertainty was the problem presented by the MOPTA Committee in January, for any student team in the world to solve by the June 14 deadline. This hospital operations problem challenged participating teams to consider a surgical scheduling problem. Their solution to the problem was required to utilize the AIMMS modeling platform, and had to give OR managers effective, quantitative and useful tools for managing staffing and sequences.

The judges found that the work performed by Alexander Tesch was outstanding. He was able to solve all models in the dataset (provided as part of the competition) to an optimal standard within a reasonable time. The key component of his solution was the use of “precedence networks” that could be solved efficiently due to the calculation of very tight bounds on some of the constants.

In addition to Team “ORopt”, finalists of the 2013 competition also included Team “OptNAR”(of Universidad Politécnica de Madrid and INTEC), Team “Universiteit Twente” (of Universiteit Twente), and Team “ORTEC”(of ORTEC, University of Amsterdam). Each of the finalists was on hand to present their team results at a dinner reception for MOPTA conference attendees.
