This paper aims to determine terminal performance and to calculate optimal throughput of a quay by port type. To this end, we have collected data, processed them, and inputted to the developed simulation model. The three port types of new port are considered to be typical of the future ports under construction or to be construction soon. The optimal throughput calculation of quay, the required number of cranes, and optimal berth occupancy can be given by using the simulation models of this study. The existing calculation methods of optimal throughput of a container terminal have mainly been based the berth capacity alone. Because of this, the container handling volume over the design capacity has rapidly worsened the traffic congestion of CY. The high density of CY worsens not only the productivity of a container terminal, but also increases sharply its logistics costs by forcing some cargoes into the ODCY. According to the questionnaire survey centring on the opinions of veteran terminal operators, the CY occupancy ratio of 60% is suitable for smooth workflow of the whole container terminal. Based on this idea, if the logistics volume is generally maintained at the level of CY occupancy of 60%, it will be reasonable and productive.
