Gemeinsame Tagung der AG Wirtschaftsinformatik (GOR) und der WK Operations Research (VHB)

Der Lehrstuhl für Decision and Operation Technologies hält am 24/25 Januar 2019 eine Tagung zum Thema "Data Science and Operations Research". Anmeldungen sind nun möglich.

Paper accepted in European Journal of Operational Research


Our paper "A Branch and Bound Approach for Large Pre-marshalling Problems" has been accepted to the European Journal of Operational Research. The paper was coauthored with Prof. Shunji Tanaka, Consuelo Parreno-Torres, Prof. Ramon Alvarez-Valdes and Prof. Ruben Ruiz. We provide new lower bounds and a specialized branch-and-bound approach for solving the container pre-marshalling problem, an optimization problem found in certain types of container terminals. Our exact approach is extremely fast, providing solutions to even large scale problems in under an hour.
