A large-scale container terminal is being built one after another in Asia as well as in Japan along with the enlargement of container ships. Together with a role of container terminal cost reduction, effective operational method is most important for shipping companies and port managers facing with international competition. In order that the condition of a Hub port is maintained by container ports of Japan, fast, cheap, and reliable delivery of container cargo is a must. Precisely speaking it is necessary to satisfy shippers with QCD (quality, cost and delivery) to prevent the hollowing of container port operation and logistics. As for Q quality of logistics for 24 hours, as for C inexpensive port and terminal charges, and as for D is the reliable time of delivery. In Japan apart from Q and D, C is so expensive no matter who sees it that there seems to be no victory. Asian ports are enthusiastically constructing modernized ports as a new and powerful nation project. In the port of Kobe the utilization of gantry cranes is remarkably low with 20〜30%, whereas the operation rate of the port of Hong Kong is high with about 80%. Low utilization makes terminal expenses higher per every container handled, as well as the considerable decrease of the competitive power of the port itself. With the aid of computer simulation of container handling in port, performance were compared between container terminal systems with cooperative operation within a group of adjacent terminals versus independent operation at each terminal. As a result, the improvement of facility utilization is expected in the joint usage of several container terminals if the public port management policy of first-come, first-served priority is adopted.
