The adequate container terminal with high performance is required to satisfy the needs of customers such as cargo owner, shipping company and forwarder. In particular, increase of service time for chasses from outside in container terminal and in front of its gate is problem on waiting loss for forwarding agent and on container distribution to hinterland. Higher container throughput is required for needs of efficient container distribution. The purpose of this paper is to evaluate functionality of efficient container terminal and to consider for higher performance of container terminal. First, the process information of container operation is extracted through the database that is constructed by analysis of the daily work report of practical container terminal. And the formulae of skill factor of transfer crane operator including a driving speed and some troubles of machine is defined, and this skill factor is calculated by comparison of operation time of constructed database and defined the standard for operation time. Finally, a Petri-network model of container handling is proposed for estimation of performance of container throughput.
