Facility layouts including the geometric features and the specifications of container terminal as well as the number of installation of gantry cranes heavily influence the performance of container terminal. Therefore, the operational impact caused by different facility layouts is worth studying.
This paper adopts simulation as approach to deal with the studied problem. A simulation model is devised to regeneration the container terminal operations. The model takes into consideration of the core constituent aspects of container terminal operations, i.e., the assignment of berth and the assignment of gantry cranes, deliberately. The model keeps tracing the occupation of berths and gantry cranes. What is new on the matter of assignment of berth is that the model not only explicitly checks the available length and depth of all berths to see which berths can accommodate the arrival ship but also determinate the available number of gantry cranes time by time to foresee the required berthing hours of each available berths. In addition, this model is able to handle preemption situation resulting from berthing priority.
According to the results of simulations conducted with the assumed data, this study obtained three findings: 1) Quay is always better than pier in the mean and the deviation of ship’s waiting time, ship’s in-port-time, and ship’s productivity. Because quay has higher chance than pier to make use its berths and gantry cranes. 2) The shallow berths should not be put in the middle of the terminal. Because that could prevent a ship from berthing in case that the shallow berth is not deep enough and the adjacent berths are not long enough. 3) A proper number of gantry cranes must be carefully evaluated. Too few in number could result in a situation which none of gantry crane being available for a berthed ship.
Key words: container terminal, simulation, container terminal performance, gantry crane.
