 Most existing capacity models are based on the use of simulation, mathematical programming or queueing network models. Empirical formulas are used to calculate the berth, yard and gate capacities for a year. This method has often been used because of its simple measures of port capacity. However, empirical measures of port capacity have been criticized due to the volatility that can change the input value arbitrarily for the measure of port capacity. Simulation models introduced in this chapter include berth, CY, gate and AGV operation. Berth simulation reproduces the process of ship call, waiting, berthing, unloading/loading, and departure of ships at the terminal through simulation. As a result of berth simulation, berth capacity, container throughput, the occupancy of berth, the number of calling ships, GBP, NBP, ship service time, the number of cranes per hour are derived. Yard simulation keeps containers brought in from the gate, railroad, the mother ship, and feeder ship for container dwell time. After a certain period of time, they are taken out to the mother ship, feeder ship, gate and railroad. As a result of the yard simulation, the capacity of the yard and occupancy by container type are derived. Gate simulation measures whether the number of designed gate lanes are appropriate, how many trucks are waiting at the gate and LSTP (Land Side Transfer Point), and what is the truck turnaround time. AGV simulation proposes which method is appropriate through the performance of Lift-AGV and non-Lift-AGV. It also measures the AGV's performance on the number of blocks, which are the number of containers transported by AGV for an hour
