Abstract: High volumes, short buffer times and many other players influence the maritime transport chain and intraport container transport. Congestion at logistics hubs leads to inefficient processes, increased waiting times, costs and emissions. Truck appointment systems are designed to reduce congestion by offering trucking companies time slots for delivering or collecting containers. However, these systems lack flexibility, which limits utilization and reduces efficiency. The study aims to develop strategies to evaluate and improve these systems in a simulation study. The results show that medium-length time slots improve the situation for transparent processes, or long time slots for limited transparency. Overbooking and open access are mutually exclusive, but offer slight advantages individually. Adjustments to opening hours of other nodes show little benefit. Overall, flexibility options positively influence the ratio of load trips and waiting times.
