Simulation Model of Smart Port

Park, Nam Kyu

nbsp;Most existing capacity models are based on the use of simulation,mathematical programming or queueing network models. Empirical formulas are usedto calculate the berth, yard and gate capacities for a year. This method has often beenused because of its simple measures of port capacity. However, empirical measures ofport capacity have been criticized due to the volatility that can change the input valuearbitrarily for the measure of port capacity.Simulation models introduced in this chapter include berth, CY, gate and AGVoperation. Berth simulation reproduces the process of ship call, waiting, berthing,unloading/loading, and departure of ships at the terminal through simulation. As aresult 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 perhour 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 takenout 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), andwhat is the truck turnaround time.AGV simulation proposes which method is appropriate through the performance ofLift-AGV and non-Lift-AGV. It also measures the AGV's performance on the numberof blocks, which are the number of containers transported by AGV for an hour
