Abstract

This study deals with an integrated problem for deciding sequencing and storage location of export containers together at its receiving operation in the container terminal with a perpendicular layout. The preferred storage location of an export container varies with the priority of the corresponding loading operation and the waiting time of an external truck depends on its storage time. This paper proposes the mixed integer programming model considering the expected arrival time and expected finish time of an external truck and the preferred storage location for its loading operation. And we suggest the heuristic algorithm based on a simulated annealing algorithm for real world adaption. We compare the heuristic algorithm with the optimum model in terms of the computation times and total cost and the performance of the heuristic algorithm is analyzed through a numerical experiment.

본 연구는 수직 배치형 컨테이너 터미널에서 반입되는 수출 컨테이너의 작업순서와 장치위치를 결정하는 통합 문제를 다루었다. 수출 컨테이너에 대한 선호 장치위치는 대응하는 본선작업의 우선순위와 밀접하고 외부 트럭들의 대기시간은 장치 소요시간에 좌우된다. 본 연구는 외부 트럭들의 예정도착시간과 예정완료시간 그리고 적하작업의 선호 장치위치를 고려한 혼합정수모형을 제시하였다. 그리고 현장 적용을 위해 시뮬레이티드 어닐링에 기반한 휴리스틱 알고리즘을 개발하였다. 목적 함수값과 계산시간의 관점에서 최적 모형과 휴리스틱 알고리즘을 비교하였고 수치실행을 통해 휴리스틱 알고리즘의 수행도를 분석하였다.
