Paper accepted in European Journal of Operational Research

2019-04-23

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.
