선석계획 및 크레인 일정계획은 컨테이너 터미널에서 입항하는 선박들의 빈번한 변동상황에 능동적으로 대처하고 유연하면서도 신속한 의사결정이 가능하도록 여러 명의 전문가가 장기적인 계획을 바탕으로 지속적으로 수정 보완해 나가는 방법으로 이루어지고 있다. 본 논문에서는 선사 및 컨테이너 터미널에서 수시로 변경되는 다양한 요구조건을 수용하는 최적의 선석 및 크레인 일정계획 수립을 위하여 제약만족기법과 휴리스틱 교정(Heuristic Repair)기법을 이용하였다. 선석계획 및 크레인 일정 계획문제는 기본적으로 제약조건 만족문제로 정형화할 수 있지만 선박의 접안위치를 결정하는 문제는 목적함수를 가지는 최적화문제이다. 따라서 이 문제는 제약조건 만족문제와 최적화문제가 혼합된 문제(CSOP, Constraint Satisfaction and Optimization Problem)로 볼 수 있다. 이러한 문제를 해결하기 위해서 각 선박의 최적 전압위치를 찾고 최우선 순위 선박의 최적 접안위치로부터 주어진 모든 제약조건을 만족하는 해를 찾는 탐색기법을 활용했고 휴리스틱 교정기법을 사용해서 제약만족기법에서 찾은 해를 교정했다. 우선순위가 가장 높은 선박부터 탐색을 하기 위해 Variable Ordering 기법을 사용했고 그 선박의 최적 접안위치부터 탐색을 해 나가는 Value Ordering 기법을 사용하였다. 실제 부산 신선대 컨테이너 터미널의 선석계획자료를 사용해서 실험을 하였다.

The Principle objective of this paper is to introduce a systematic approach to identifying similar container ports in Asia. For this, it analyses data on port facilities, port facility availability, port service level total container throughput, and economic index, by using Multidimentional Scaling (MDS) method. Based on the analysis it identifies five groupings of similar container ports in Asia within which Port comparison can be justifiably made, evaluates a present position of five groupings on the basis of factors used to compare container ports in Asia ; and finally proposes policy implications for operation efficiency of Pusan container port in comparison with Kaohsiung Port. The major implication is that both the Kaosuing and the Pusan port have to strengthen port facility to attract more traffic, and particularly, Pusan Port has to reinforce the number of berth, total length of berth. and yard areas.

In the era of the 4th industrial revolution, automated technology innovation is emerging, and container terminals are being developed to introduce automation equipment and systems. With the advent of ultra-large vessels, terminals around the world are seeking to build port infrastructure by combining automated technology in order to attract more cargo and to enhance competitiveness to provide prompt service. To introduce automated technology that is emerging as a high-tech industry, this study proposes a structural equation model for the decision to introduce automated container terminal and conducts a questionnaire survey on workers engaged in terminal operators for empirical analysis. This paper presents the role and direction of guidelines for introduction of automated container terminal through decision model.

The inefficient operation of Busan New Port is due to container-terminal operators being dispersed in small groups, rather than being integrated. This dispersion increased following the reorganization of global shipping alliances in 2016 and causes unnecessary Inter-terminal Transportation(ITT) and ship delays. Studies of integrated operations for larger container terminals show that integration is not going well, however, due to the pre-emptive task that follows the integrated operation. Therefore, in this study, we divided the integrated operation into stages based on a simulated model of the container terminals in Busan New Port. The simulation took into account future increases in the ship's enlargement and terminal congestion, and the operational effects of each type of integrated operation were analyzed and evaluated.

As the importance of container ships in maritime transport grows, the demand and supply for such vessels have been increasing. To reduce costs and improve operational efficiency, container shipping lines have formed shipping alliances, engaging in joint operations and vessel-sharing arrangements. Since the establishment of these alliances in 1995, they have evolved in various forms. In 2024, Maersk and Hapag-Lloyd announced the formation of a new shipping alliance, the 'Gemini Cooperation,' set to begin in February 2025, signaling a potential realignment of shipping alliances. This shift will significantly impact operations of ports like Busan. In the case of Busan Port, the inability of a single terminal to accommodate large shipping alliance vessels has led to an increased reliance on multiple terminals, which in turn has caused an increase of inter-terminal transportation cost and a decrease in operational ef iciency. Therefore, this paper aimed to examine changes in shipping alliances since 2012, analyze the current usage of container terminals at Busan Port, and propose strategies for efficient port operations in response to expected realignment of shipping alliances.

Shipping and ports have important roles as the nodes and links in maritime logistics. The environment between shipping and ports is interrelated and has been changing' together. Recently, the changes of shipping and ports are rapidly in progress and it is expected to be developed complementarily. Especially, mega carriers reduce the number of ports of calls because the size of ships is becoming bigger and bigger and the 'hub and spokes' strategy is appeared. Therefore, the position of a hub port by the region has questioned This paper aims to research the competitive ports by the region on the basis of the patterns when mega carriers call at ports. Six regions, Far East, Southeast Asia, Northwest America, Northeast America, West Europe and Mediterranean, are organized for this research. According to the volume of cargoes, the top five ports of each region are analyzed. As a result, the competitive ports by the region are Shanghai, Hong Kong, Los Angeles, New York New Jersey, Rotterdam and Gioia Tauro.

This study suggests a development direction by comparing the cargo throughput of the port of Yeosu-Gwangyang during 2007-2015 with that of domestic ports. It derived a concentration index (HHI) of cargo throughput in domestic ports by Yeosu-Gwangyang port docks, shipping companies, and abroad regions. The main results were as follows. First, in terms of total cargo handled, the port of Yeosu-Gwangyang was second only to the port of Busan, and the HHIs for the past nine years were relatively low. Second, the port of Yeosu-Gwangyang ranked first for total import and export cargo throughput, showing relatively stable HHIs from 2007 to 2015. Third, the HHIs of container handling performance by national shipping companies showed stable levels below 1,800. Fourth, there were no regions where cargo volume was noticeably concentrated in the port of Yeosu-Gwangyang, and it showed cargo throughput across various abroad regions. While changes in national shipping companies are expected after the Hanjin Shipping Crisis, there should be no serious concern regarding the dependence of the port of Yeosu-Gwangyang. It is expected to develop further by realizing the full use of all its facilities, diversifying the tenants in the Yeosu-Gwangyang area, and improving the demurrage rate.

Busan Port which is the representative social overhead capital facilities for international trade of goods has need the driving force for economic development in Korea. Therefore, the central government should play the major role in building a rear road to Busan Port in order that it may function as a moor port of Northeastern Asia through the systemization of mutual assistance among connected facilities, completely equipped with port-related facilities befitting to the principal port of imports and exports. In this study, the validity of container tax is being examined, analyzing container tax which is considered as an obstacle to the development of Busan Port and its purpose, and grasping the present conditions by the realistic speculation on container tax issues and its abolition. First, the port rear road as a social overhead capital facilities, which connects port and expressway, should be considered as part of port, and port is social overhead capital invested by government. Second, the Busan City imposes taxes on container. As a result, a shipper and a shipping company are paying a double charge by paying container tax with port dues. Third, Empty container and Tranship container are the factor of Busan city traffic jam but their was excluded from container tax. This is deviate from equilibrium of the tax object. Forth, it has bad influence upon the competitiveness of Busan Port as Northeastern logistics base, as other ports who are competing with Busan Port like china, Taiwan, Japan's port make their competitiveness strong by decreasing the cost of port dues.
