BRAIN-TRAINS (2014-2018)

BRAIN-TRAINS deals with rail freight intermodality, and the extent to which it can be made successful, under market, society and policy-making challenges, and analyzing how intermodality contributes to answering these challenges. Starting point is the relative weak usage of this type of transport.

Potential of Liege as inland container port

The Ports and Logistics Advisory together with the University of Liege, Prof. Sabine Limbourg, have executed a study on the potential of Liege as inland container port and resulting business opportunities for companies in transport & logistics. The study is commissioned jointly by AWEX (the Export & Foreign Investment promotion agency of Wallonia) and Port of Rotterdam Authority. The Liege Port Authority fully supports the study.

START – POCAT (2010-2013)

Planification et Optimisation des Chaînes d’Approvisionnement et des Transport

The research project consists of analyzing planning and decision optimization problems faced by enterprises in the context of their production and transportation activities. The research activities are motivated, on one hand, by real-world problems faced by the partner enterprises, and on the other hand, by more theoretical scientific studies. Our studies concentrate currently on rich vehicle routing problems faced by retail and food distribution chains. We develop a column generation based branch and bound method to be able to solve to optimality instances of reasonable size. With the aim of proposing good solutions for large instances, we develop metaheuristics that combine variable neighborhood search (VNS) methods and large neighborhood search (LNS) methods.

FOREM (2009-2010)

Research concerning the evolution of job contents, competencies and training required by employers in the logistics sector.
Supported by: FOREM (Walloon Public Office for Employment and Training)
Main actors: Y. Crama and Y. Arda(coordinators for QuantOM), V. François, R. Nondonfaz.

TransLogisTIC (2007-2009)

Acronym of Transport, Logistics, and Technologies of Information and Communication, TransLogisTIC (http://www.logisticsinwallonia.be/translogistic http://www.logisticsinwallonia.be/translogistic) is a project supported by the Walloon Region within the framework of the "Marshall Plan". The project is aimed at developing a complete and efficient multimodal transport system in Wallonia as well as high quality logistics services with high added value. The contribution of HEC-ULg consists in elaborating models and algorithms of optimization for real-time vehicle loading operations.
Supported by: Walloon Region
