Abstract: The proper allocation of vessels to berths represents a significant challenge that aims to utilise resources efficiently whilst providing good service to the vessels. This task is exceedingly complex when considering real-world constraints such as tides, draught, access channels, service times, speeds, and berthing and unberthing priorities. In this work, the berth allocation problem (BAP) is integrated with the channel scheduling problem (SChP) and the real constraints existing in maritime ports. To address this problem, we developed a mixed-integer linear programming model and compared it with a model presented in the literature. The results show that, by considering the real constraints of ports, vessel scheduling can change significantly.

Keywords: berth allocation; discrete berthing; access channel; tides; navigation speed.
