After studying the real system and building an overall understanding of the on-going operations, a conceptual
model can be inferred and constructed. Entities moving within the simulation model include ships, trucks, trains and
containers. The resources in the model include quay cranes for loading and unloading, RTGs for stacking and
unloading, ship berths, and storage areas or container yard. The processes in the model are constructed based on the
operations that take place at the port including loading/unloading containers from sea or land and moving containers
to the container yard or around the port to another transportation mode. Fig 1 shows the flow chart of the port and
the processes involved.
The proposed simulation studies different scenarios regarding the number of cranes, RTG, and yard trucks to
understand their impact on the port progression. Furthermore, the simulation model is set up as a platform to study
the impact of customs and security check points on the port .
