최근 컨테이너 터미널의 생산성 향상을 위한 자동화가 국내외에서 활발히 이루어지고 있다. 이에 따라 자동화 컨테이너 터미널의 주요 자원을 효율정으로 운영하는 방안에 대한 연구가 진행되어 왔다. 본 논문에서는 자동화 수평 장치장을 대상으로 ATC 작업 할당 휴리스틱과 YT 배정 휴리스틱을 조합하여 시뮬레이션으로 평가해 본다. 더불어 효율적인 장치 전략과 YT 풀링 범위를 알아보고자 한다. 실험 결과 연구되는 본선 작업들을 두 기의 ATC가 하나씩 번갈아 가며 수행하도록 컨테이너를 분산 장치하고 ATC의 작업 예상 완료 시각을 고려하여 마감 시각이 가장 빠른 작업을 우선 처리하는 작업 할당 휴리스틱과 터미널 전체에서 가장 먼저 올 수 있는 YT에 작업을 배정하는 휴리스틱 조합이 가장 효율적 이었다.

Remarshalling operation is one of the operations considered important in an automated container terminal to perform quickly loading operations and delivery operations. It arranges the containers scattered at a verticla yard block in order to reduce the transfer time and the rehandling time of ATC(Automated Transfer Crane)s. This paper deals with the remarshalling planning problem minimizing the weighted operation time. This problem can be decomposed into 2 subproblems, storage space assignment problem and operation sequencing problem Storage space assignment problem decides to where containers are transported in terms of transportation time cost.. With results of a previous subproblem, operation sequence problem determines the ATC operation sequence, which minimizes the dead-heading of ATC This study formulates each subproblem with mixed integer program and dynamic program. To illustrate the proposed model, we propose an instance to explain the process of remarshalling planning.

The objective of this study is to analyze the efficiency of marshalling work using ATC(automated transfer crane) for ACT(automated container terminal). It is important fact to assignment of containers, because the character of ACT which block layout is vertical for berth and there are four other works which are inbound, oubound, loading and unloading in one block. And then there is need which assignment of containers with remarshaling work using ATCs in one block. Therefore, we analyze the efficiency of remarshaling work using simulation and suggest the assignment methodology of containers in yard

It's important to operate the yard for improving to the productivity in container terminal effectively. Because the automated container terminal(ACT) has storage yard of automation and horizon, it's character is different from conventional terminal. As the automation yard in ACT is operated by the automated equipments, it needs to an efficient storage plan which is connected the automated equipment, the external truck, the shipment etc.. Hut the traditional method of storage plan is the space assignment problem. The efficiency of yard decreases and it is brought about increase of shipment time, because real-time automated equipments and present yard status is not reflected in. In order to solve this problems, we propose the algorithm for real-time storage location of container considering shipment plan, yard status and the state of ATC.
