Abstract

This research develops a berth scheduling simulation model to solve the Berth Scheduling Problem at a container terminal. Berth scheduling is influenced by the vessel’s arrival time, because it will affect the availability of the quay and material handling. The vessel needs material handling for loading and unloading process in container terminal, there are quay cranes and internal trucks. The internal truck moves the unloading containers from quay to the container yard and the loading containers from container yard to the quay. When the loading and unloading process of a vessel is running, an internal truck is dedicated to a quay crane until the loading and unloading process of a vessel is complete. The number of quay cranes serving a vessel is determined based on the LOA (length over all) of vessel. The quay crane will start loading and unloading when the internal trucks arrive at the quay. It often causes the quay cranes and vessels to wait for loading unloading process. In addition, this will have an impact on the berthing time of the vessel and the waiting time for other vessels that will berth. This research develops a berth scheduling simulation by considering the arrival time of the vessels and internal trucks to get the vessel’s berthing schedule and assign the quay crane by minimizing waiting time and berthing time.
