Stephane Zampelli: Berth Allocation and Quay Crane Assignment using Constraint programming

In this talk we will tackle the berth and crane allocation problem arising in large container terminals and describe a constraint programming approach able to model many realistic operational constraints. The costs for berth allocation, crane allocation, time windows, breaks and transition times during gang movements are optimized simultaneously. The model is richer than the state of the art in the operations research community. Experiments show that the model produces solutions with a cost gap of 1/10 (7,8%) to 1/5 (18,8%) compared to an ideal operational setting where operational constraints are ignored.
