WORKING TIME ANALYSIS OF RTG AT CONTAINER TERMINAL AND APPLICATION TO CONTAINER HANDLING SIMULATION MODEL

Abstract

 Container handling simulation of container terminals is a technology to reproduce the movement of container handling machines and containers in a yard on a computer, and to use it for planning the layout of container terminals and evaluating and studying measures to improve their operation. In this container handling simulation model, parameters such as the loading/unloading time of RTG (Rubber Tired Gantry Crane) are generally calculated from the catalog values. However, in actual loading and unloading operations, the catalog cycle time deviates from the actual cycle time because efficient operation trajectory are taken depending on the container stacking situation of stacking bays. In this study, we compared the daily report data of RTGs obtained at container terminals and the results of work observation using camera images installed on RTGs, and studied a method for estimating the container handling time of RTGs using the daily report data. The estimated work time were aggregated for each storage coordinate in the bay, and their characteristics were analyzed. The estimated work time for each storage coordinate were used as input parameters in a container simulation model, and the reproducibility of simulation model was confirmed.
