Abstract

본 연구의 목적은 컨테이너터미널에서 야드 트랙터의 요구수량을 추정하는 것이다. 야드 트랙터의 수는 컨테이너터미널의 효율을 결정짓는 애로요인이며, 운행 속도와 운행 거리에서의 변화로 인해서 그 효율성을 추정하기가 어렵다. 야드 트랙터의 효율은 컨테이너 크레인과 트랜스퍼 크레인간의 대기네트워크를 고려하여 개발된 시뮬레이션 모델에 의해 추정된다. 컨테이너 크레인당 야드 트랙터의 수는 대안 분석에 의해서 추정되며 컨테이너 크레인당 야드 트랙터의 수를 결정하기 위해서 선석과 야드간의 거리와 야드 트랙터의 속도와 같은 평가척도를 시뮬레이션 하였다. The purpose of this study is to estimate the required number of yard tractor on port container terminal. The number of yard tractor is the bottleneck factor on the efficiency of container terminal. Due to the change in travel speed and travel distance, the efficiency is difficult to estimate. The efficiency of yard tractor is estimated by the proposed simulation model that developed considering the queueing network between container crane and transfer crane. The number of yard tractor per container crane is estimated by the alternative analysis. And to determine the number of yard tractor per container crane, the performance measure such as the distance between berth and yard, the speed of yard tractor are simulated.
