Abstract

Due to the increase of container terminals, as the volume of terminals become distributed, the competition of preserving existing volume and inviting new volume are becoming fierce, and various ways for processing terminal volume and inviting volume are being sought. Container terminal efforts to maximize efficiency in order to improve the volume handling capability and productivity by both expansion of the latest equipment and development of the latest terminal system. There are a variety of factors that influence the improvement of productivity at container terminals. Among them, in the case of yard transfer equipment, if it were to convert from the method of a Yard Tractor(YT) being fixed allocated to a certain Gantry Cranes(GC) to a Pooling System that processes in a method that properly distributes and allocates a Yard Tractor(YT) to multiple Gantry Cranes(GC), the terminal productivity and the fusibility of YT may be increased. The KPI which is an indicator for the productivity at container terminals is GC productivity and since GC productivity cannot exceed the speed of physical GC operations, a Pooling System is applied to increase productivity which its meaning and effect is massive. Here in the Report, we produce the Pooling Algorithm system to improve the efficiency of the transported equipments in container terminal which is actually applying for this method and have compared Non pooling system with Pooling system in the fields. By introducing a transfer equipment pooling system and enhancing the productivity compared to other terminals, it may become an essential factor for increasing the continuous service quality and profitability in terms of terminal business.

컨테이너터미널의 증가로 터미널 물량이 분산되어 기존 물동량 보존과 새로운 물동량 유치 경쟁이 치열해지고 있으며 이에 터미널 물동량 처리 능력과 유치에 다양한 방법을 모색하고 있다. 컨테이너터미널은 물동량처리 능력을 향상시키기 위해서 최신 장비 확충과 최신 터미널 시스템 개발을 통해 터미널의 생산성 향상과 효율성 극대화에 노력을 기울이고 있다. 컨테이너터미널의 생산성 향상에 영향을 줄 수 있는 요인은 다양하게 존재 한다. 그중 야드 이송장비의 경우, 특정 선석크레인(GC, Gantry Crane)에 야드 트랙터(YT, Yard Tractor)가 고정 할당되는 방식에서 다수 선석크레인(GC, Gantry Crane)에 야드 트랙터(YT, Yard Tractor)가 적절하게 분산 할당 방식으로 처리하는 Pooling System으로 전환하게 되면 터미널 생산성과 YT의 가용성을 높일 수 있다. 컨테이너터미널에서 생산성 지표가 되는 KPI는 GC 생산성이고 GC 생산성은 물리적인 GC 작업 속도를 넘어설 수 없기에 Pooling System 적용하여 생산성을 높이는데 의미와 효과는 크다. 본 논문에서는 컨테이너터미널에서 생산성 향상을 위해 이송장비 운영을 더 효율적으로 할 수 있도록 Pooling System 알고리즘을 제시하고 실제로 컨테이너터미널에 적용하여 Non Pooling System과 Pooling System 생산성을 비교하였다. 이송장비 풀링시스템을 도입하여 타 터미널에 비해 생산성을 향상함으로써 터미널 비즈니스에 있어 지속적인 서비스 질과 수익성 향상을 위한 필수불가결한 요소가 될 수가 있다.
