Functional Design Based on Cargo Handling Operation Data Analysis in Container Terminal at Sea

Abstract

Container terminal is a important base point for physical distribution to connect between land and sea transportation. The highest priority on container transportation is given to time value to satisfy the requirement of customers under the present situation. Providing higher performance at container handling to container ship is the top priority at container terminal. But, this priority occasionally causes some problems such as to deploy excessive facility for container handling cargo gear, to suspend container handling to chassis from outside, which might influence the management for container handling. The purpose of this paper is to evaluate improvements by functional design based on analysis of container handling operation. The process data of container handling operation for cargo gears are obtained to develop the datalog system for gantry crane operation, to construct the container handling data base for transfer crane operation and to study a process data by work sampling for chassis operation. Petri-network model of container handling is constructed to based on the process data. An important consideration for adequate numbers of container handling gears is carried out to apply the developed methodology, as a trial calculation.
