Abstract
As terminals and liner shipping companies face increasing congestion and tighter berth line-ups, the effective scheduling of vessel operations in terminals has become a critical factor in port operations. To tackle this challenge, we introduce a mixed integer linear programming (MILP) model designed to optimize berth scheduling in maritime terminals with high transshipment volume. This model prioritizes the liner’s operational efficiency by optimizing schedule reliability, transshipment success, and bunker consumption, as well as respecting terminal resources availability, i.e., crane availability and yard capacity.
The main contributions of this work are twofold: (i) include transshipment success as part of the objective function to optimize berth line-ups in terminals with high transshipment volume, (ii) constrain berth line-ups to respect yard capacity limits. The former has a considerable impact on the liner’s commercial performance and has only been studied in a small number of previous works. The latter adds a new capacity dimension that is critical for terminals handling high levels of transshipments and has not been addressed in previous work.
The proposed MILP model has demonstrated substantial business value by ensuring that thousands of containers are successfully transshipped, while reducing delays on vessel schedules and bunker consumption.
