컨테이너 터미널의 블럭 내 효율적 재정돈 작업에 관한 연구

Abstract

In-stack shuffling means to get new position on the top tier in same bay with a minimum movement from original position for picking up and putting on the chassis of the Internal tractor (hereafter it is called YT)or, to get new scheduling from 섞임(Mixing Level)ed container working queues for loading operation in same bay. If operating system could not find new position on the top tier for next work queue in advance, or driver did not re-shuffle the container according to work sequence in time before YT arriving under the RTGC, then YT have to wait to shuffle accordingly. It means the quay crane’s total productivity decrease. To reduce waiting time of YT under RTGC, operating system or RTGC operator do the shuffling in time but previous shuffling in sufficient hour by driver could not make maximized effect due to actual situation change at the very time to pick up. So system has to be designed minimum shuffling under workable and practicable conditions. In consequence in this paper I will find the feasible solution under constraints and this feasible solution will be verified by simulation
