평택 당진항은 지난 1996년 3대 국책항만 및 5대 국책개발사업에 선정된 이래 단기간 내 급속한 항만성장을 이룬 결과 지난 10년전과 비교하여 선석규모는 약 3.2배 증가하였으며, 지속적인 항만개발계획에 따라 2030년까지 총 92선석을 개발할 예정이다. 이러한 항만규모의 증가와 함께 선박입출항 및 화물처리실적 또한 2015년도 기준 전국 5위의 규모로 성장하였다. 하지만 항만의 수심, 항로폭, 정박지 규모 등 선박통항을 지원하는 기반시설의 개발은 상대적으로 부족하여 통항안전의 저해요소로 작용하는 바 이러한 항로와 정박지를 중심으로 선박통항안전에 부정적 영향을 끼치는 요소를 분석하고 그에 따른 개선방안을 모색해보았다.

컨테이너 터미널에서의 선석 및 크레인 일정계획은 일정 기간 동안 입항 예정인 선박들을 대상으로 접안 위치와 접안 시기 및 기간을 결정하며, 또한 각 선박별로 컨테이너를 싣고 내릴 크레인을 배정하되 각 크레인의 서비스 시작과 완료시간가지 지정하는 전 과정을 포함한다. 이 문제는 여러 선박들 사이의 시간적 공간적 제약관계를 준수하고 크레인들을 충돌 없이 각 선박에 할당하여야 하는 제약조건 만족 문제인 동시에, 각 선박의 선호 위치와 희망 입출항 시간을 최대한 준수해야 하는 최적화 문제이기도 하다. 기존의 연구에서는 제약만족탐색기법을 사용하여 초기계획을 수립한 후 최적의 해를 유도해 내기 위해 휴리스틱 교정기법을 제약만족 탐색기법의 틀 내에서 반복적으로 적용하였다. 본 논문에서는 반복적 개선 탐색 도중에 도출되는 해의 정보를 이용하여 새로운 제약조건을 추가함으로써 다음 제약만족 탐색 시 보다 쉽게 더 충은 해를 찾을 수 있도록 하였으며 이 방법을 기존의 휴리스틱 교정기법과 결합하여 휴리스틱 교정기법의 성능을 향상시켰다.

선박이 지정된 선석에 안전하게 접안하기 위해서는 도선사와 예인선의 도움이 필요하다. 접안 과정에서 선박이 선석까지 남은 거리와 접안 속도는 선박에 탑승한 도선사와 선원들의 육안에 의존하는 경우가 많으므로 안전에 대한 위험 요소가 있다. 본 연구에서는 접안 과정에서의 위험요소를 줄이고, 접안에 도움을 줄 수 있는 인공지능 센서 기반 선박 접·이안 정보 추출 기술을 개발하였다. 개발 기술은 임베디드 시스템과 클라우드 시스템에서 구동되며, 인공 지능 영상처리 기술과 센서 융합 기술을 기반으로 측정한 접안 중인 선박의 운동 정보를 접안 이해 관계자들에게 서비스한다.

Competition between international Hub ports has been more and more intense. In order to invigorate itself, Gwang-Yang port has been making multilateral efforts. However, it has not still reached 300Millions TEU which is the standard to be permitted as a self-reliance Hub port. Therefore, a functional modification of berth should be considered. This study suggests to transform container berths to general berths. This article is focused on reserve berth mode of Gwang Yang hub port and selected three kinds of berths as alternative subjects of the study: general berth, exclusive berth, and multipurpose berth. This research has conducted that The subjects of the survey were in relation with Logistics as professional mutually group about Gwang-Yang hub port. The measurements of this survey were measure section and factor. Also, Fuzzy AHP(Analytic Hierarchy Process) was applied to the survey. According to the result, by measuring weight values of alternatives, the best favored one was multipurpose berth expect stability (32.6%), Exclusive berth was graded the most among the alternatives. Also, based on total weight value, the order of priority is as follows: multipurpose berth(38.2%), exclusive port(33.7%), general berth(28.1%).

The improvements of berth productivity is closely related to berth/port systems and its relationship extends to the overall pattern of port development/logistics, transport and trade. Since ports in general and berths in specific function as a bridge transferring seaborne cargoes from seaside to landside and vice versa, berth productivity improvements should be considered in terms of the total system in which the cargoes are transported from origin to destination via berths/ports. In that respect, the objective of this study is to improve berth productivity which is a vital factor in the strategic planning in port development and operation and logistics. According to a literature survey on the subject, the contents of the studies have been limited to either a macro-perspective or a micro-perspective which is only a partial solution to the problem. Hence, this limitation requires an integrated approach to find and ultimate solution, which should be considered not separately, but as a whole. The contents and scope of this study cover the improvements of berth productivity in conjunction with strategic planning in port development. efficient operation and logistics from two different viewpoints, macro- and micro-perspective. After that, a combination of these two perspectives is applied to the integrated approach due to lacking a comprehensive perspective from either macro-approach or micro-approach. In reality, a port itself is a complex and dynamic organization. Therefore, a comprehensive insight needs an integrated approach for the long-term national economic development. In this approach, the utmost importance is how to find the bottlenecks and to solve the problems effectively from the beginning stage in port development. In conclusion, derived from the macro- and micro-perspective. the attempt to establish an integrated approach is the merit of this study, which is required as a comprehensive measure since none of the two can be a solution independently. In terms of reinforcing this study, it needs further empirical research due to the restriction of the theoretical method of this paper. Consequently, the reinforced research will be able to enhance the integrated approach on the basis of the conceptual perspective.

The purpose of this paper is to develop a knowledge-based real-time decision support system to support decision makers for efficient berth operation of Inchon Port. In these days the berth operation problems have been many studied. The berth operation rules differ from port to port and the problem is highly dependent on natural geographical and operational environment of port. In Inchon Port the ship’s entrance into port and departure from port is extremely affected status of dock. In this paper we analyzed some effects of dock a specific character of Inchon Port with a real data of ship’s in Inchon Port. And reconstruct a previous expert’s knowledge of berth allocating problem in Inchon Port. Also the mechanism for the efficient berth operation has been studied by repeatedly dispatching in order to obtain a best effect of berth allocation, with real-time updated information for delay at service time of a specific berth and changing of a working-berth. The system is developed with graphic user interface(GUI) concept using user interactive approach. And this system will be provide decision support maker with an efficient and fast way to berth allocating and reduce wastes of time space and manpower in Inchon Port operation.

The purpose of this paper is to evaluate the efficiency of two yard layout of HSS at container terminal, one is that the container yard blocks are placed horizontally in parallel with berth, the other is that the yard blocks are arranged vertically in perpendicular to the berth. In stevedoring system of container terminal, stacking and transport performance are influenced according to block arrangement type of yard. Therefore, efficient design that can improve stacking and transport performance is required. In this paper, we compared their efficiency of two block arrangement concepts in terms of storage capacity, productivity, facility investments, truck service level.
