The states of ship's waiting for berthing are increasing in number, because congestion problems in Japanese many ports are becoming worse year by year. Waiting time has a great influence not only on the ship owner's disadvantage but also on physical distribution cost. So that authors tried to solve a congestion problem through simulation which using the change of parameter of elements -the average number of the ships entering the port in a day, the number of berths, the amount of the cargo loaded on each vessel and the cargo handling rate- on basis of the present situation's data. As a result, Ship's waiting time would be reduced to nothing if the utilization factor of berth is kept within 0.6 except at the nighttime when all the vessels are prohibited to enter port. It is necessary to consider the four elements on the planning stage of berth and ship's operation as the four elements are in the correlation.
