nbsp;For futuristic planning of smart port, it is very important to measure terminalcapacity considering service indicators such as ship waiting ratio, berth occupancy,yard occupancy, and truck turnaround time. The capacity of a port proposed byUNCTAD is divided into intrinsic capacity and proper capacity. The intrinsic capacityis calculated on the assumption that the unloading/loading of the ship is operated 24hours a day for 365 days per year. On the other hand, for the proper port capacity, theutilization ratio of the quay crane, the berth occupancy, and the actual number ofavailable workdays of berth as service level are considered in order to calculateappropriate port capacity.This chapter explains the basic mathematical theory required to calculate the propercapacity of smart port considering service level. The proper service of the berth isdetermined by the ship's waiting rate. Ship waiting ratio and berth occupancy have apositive relationship. Suppose there are 4 berths providing constant service in berth,60% occupancy and 10% ship waiting ratio are calculated as an appropriate servicelevel. The yard's capacity depends on the yard occupancy of 60% and the turnaroundtime within 30 minutes of the external truck. This value varies depending on thecircumstances of the terminal.
