오늘날 글로벌 수 출입 공급망 내에서 항만 하역작업의 효율성은 아주 중요하다. 해상운송에서는 컨테이너화와 더불어 늘어나는 화물량을 극복하기 위해서 초대형선의 운항이 일반화 되고 있다. 따라서 컨테이너 터미널의 관리자들은 안벽작업의 효율성을 극대화하기 위하여 더블 사이클과 듀얼 사이클 방법을 시도하고 있다. 또한, 야드 트랙터의 할당의 효율성을 높이기 위해서 야드 트랙터 풀링 방법이 제시되었다. 본 논문에서는 기존의 풀링 방법들과 듀얼 사이클을 고려한 풀링 방법의 비교를 통해서 듀얼 사이클의 효율성을 분석하였다. YT 할당 모형은 시뮬레이션 분석 소프트웨어인 Arena를 이용하여 수립되었다. 실험결과 듀얼 사이클이 많은 것이 항상 크레인 생산성을 높이는 것은 아닌 것으로 분석되었다.

항만국 통제 점검(Port State Control Inspection)은 해양 선박사고의 대부분이 선박 자체의 결함 보다는 인적 과실에 의하여 발생되고 있다는 사실을 인지하고 선박을 운항하고 있는 선원의 자격 검증과 교육훈련 부문의 점검을 강화하고 있다. 이에 따라 날로 강화되고 있는 국제 협약과 국제 법규를 충족시키기 위한 선원의 재교육훈련을 어떻게 효과적이고 효율적으로 시행하느냐가 해운기업에 있어서 풀어나가야 할 숙제라 할 수 있다. 이에 본 연구에서는 국내 S사의 피 교육자들을 대상으로 설문조사를 실시하고 연령, 학력, 근무연수, 직위 등을 기준으로 응답자를 분류하여 교육 훈련의 목적 및 필요성, 자기 동기부여, 교육효과 및 성과, 교육훈련의 만족도 등 4개 항목에 대한 인식의 차이를 분석하고 교육의 효과를 높일 수 있는 교육 방안 수립을 위한 시사점을 도출하였다.

Technological and organisational changes in transport system have introduced new dimension into port system development and inter-port competition. The quality of service now required by the customer is costly and not easily provided by small shipping companies and small ports. It has been suggested that in the future container shipping may be concentrated by space-sharing arrangements or actual mergers into the hands of a few mega-operators with the investment potential to provide total logistics networks. In order to compete effectively, high load factors will be essential and port concentration inevitable. A fa-voured few ports will become the load centres and other ports will assume a secondary feeder role. In this study, three questions are raised and attempts are made to answer them : (a) what is the new role of ports today ; (b) why should ports be engaged in this new role ; and (c) how can ports play this new role. In short, a modern port should be a service centre and a logistic platform for international trade and transport-a third generation port. Ports, in particular, have to make every effort to be competitive in the cost and quality of services and to make the port a transport and distribution service centre. For most ports, this is not an option but a must ; an essential requirement for survival in this win or lose situation. The best way to win is to maintain a close contact with port users, listen to them, discuss with them, help them and satisfy them. That is port marketing. Starting from the findings of port marketing, it is es-sential to work out appropriate development plans and marketing targets and to improve port competitive-ness. As an alternative method, a port competitiveness model is suggested, which may help port managers to make appropriate improvements.

In order to attract more transshipment cargoes, Busan Port Authority (BPA) has, since 2003, adopted the volume incentive policy by which more than US$ 10 million annually have been paid back to shipping lines that were called at the port. However, having been a transshipment port for the Northeast region of China, the port of Busan has come under threat from bold Chinese port development projects, notably Shanghai, as northern Chinese regionnl ports place more emphasis on building facilities capable of handling growing trade volumes. Undoubtedly this would lead to a decline in transshipment container traffic moved via Busan. The purpose of this paper is to identify some core factors that have been affecting the increase of transshipment cargoes of Busan and further to recommend BPA an improved incentive scheme with which more T/S cargoes can be attracted into the port of Busan To clarity the reason why T/S cargoes have increased in the port of Busan, several steps are made as follows: The first step is to make a quantitative model for explaining the development of T/S cargoes during the last decade. The second step is to define the dependent and the independent variables for multiple regressions after testing variable significance. For this, data collection and the accuracy of validation have been done by the direct interview with the experienced staffs in shipping companies of both domestic and foreign country. After validating the model with collected data, the final step is to find variables which are explaining the model mostly. In conclusion, 2 variables were clearly identified as core factors that explain well the development of T/S cargoes in the port of Busan: 'Mohring effect' and total cost. It is strongly recommended, by an empirical study, that an incentive scheme be changed to a way which more feeder vessels rather than mother vessels can reduce their direct costs to call in the port of Busan.

최근 컨테이너터미널 간의 경쟁이 심화되면서 생산성 측면뿐 만 아니라 비용경제성 측면에도 관심이 부각되고 있다. 특히, 에너지 소모량 및 장비투입 규모가 큰 트랜스퍼 크레인 부문에 대한 비효율적인 작업요소가 컨테이너터미널 경쟁력 제고에 있어서 걸림돌이 되고 있으며 이에 대한 개선은 인적, 물적 운영비용의 절감과 함께 생산성의 향상에도 긍정적인 영향을 미칠 것으로 기대된다. 따라서 본 연구에서는 현재 국토해양부 주관으로 진행 중인 'RFID를 활용한 RTLS 기반 항만물류효율화 사업'을 통하여 제공 가능한 컨테이너터미널 반 출입 대상 컨테이너의 시간적 가시성을 토대의 트랜스퍼 크레인의 배정 및 이동경로에 대한 클러스터링 기반 최적화모델을 제안하고 시뮬레이션 기법을 통하여 기대효과수준을 확인하였다.
