Today international trade through maritime transportation is significantly increasing. Due to this increase, shipping companies are faced with problems concerning the repositioning of empty containers from import dominant ports. The liner shipping service network has been provided to transport containers which load customers' freights. Container ships are moved on the liner shipping service network by observing the predetermined route and transportation time. This research deals with the empty containers distribution problem considering the container ship route. A mathematical model based on the mixed integer program has been introduced in this study. The objective is to minimize the total relevant costs of empty containers such as handling, leasing, and inventory holding, etc. Due to the complexity of the problem, a genetic algorithm has been suggested to solve large sized problems within a reasonable time. Numerical experiments have been conducted to show the efficiency of the genetic algorithm.

Globalization of production, changing technology in ocean shipping sector, shifting bargaining power from port service provider to port users, changing distribution patterns of the containerization and new implementation for the environment and safety concerns introduced new ways of administration in port sector. In these days, port industries cannot survive alone. Port operation and management has to be proactive to cooperate and integrate with other port operators or other industries. In the 21st century, cooperation in maritime sector is more common than that in the past with several different reasons in a mixture of forms of cooperation. Cooperation among port authorities, port operators, shipping line, inland transport service providers and/or related organizations themselves becomes to exist to overcome the challenges and development of the global transport chain. This paper investigates the concept of port cooperation and the case analysis of the cooperation in the port industry.

Korea is worldwide top manufacturer of offshore plant industry, while shown weakness in high-valued offshore plant service industry (OPSI). The governmental support policies and studies for fostering programs are centered on shipbuilding and engineering sector. On the other hand, offshore logistics service sector among the programs is neither included as governmental fostering support sectors nor ever-studied. Domestic shipping and logistics companies have many experience of handling various project, heavy-lift cargo and even super blocks on shipbuilding industry. However they are faced with lack of appropriate heavy carrier and others. So for their successful entering into offshore plant logistics market, systematic preparation, studies and supporting policies are highly recommended.

This study shows how the service quality of port supply industry impacts with customer satisfaction and relationship orientation. Through previous research, service quality of port supply company is considered, at the same time, the key factor of service quality is divided into tangibles, reliability, responsiveness, assurance and empathy. Sample design is based on shipping companies which are registered in Korea Ship owners' Association and Korea Ship managers' Association from Aug. 8 through 26 in 2011. And total of 275 questionnaires are collected from shipping companies in Busan and Kyong nam. Result of this study would be utilized in marketing strategy for port supply industry. In the future research, based on analysis of port supply company's characteristics, the study for port supply industry which are perceived by customers could be conducted.

E-commerce has not only brought about a great change in the way we exchange goods and services but also revolutionized the way we handle business transactions. In addition, it has a significant influence upon the present business structure, and most of firms in service industry as well as manufacturing are considering adopting E-commerce in a serious manner. Most vessels purchase merchandises through a number of shipping agents. As the amount of harbor materials increase, the number of vessels and their navigation frequency also increase. As a result, the amount of procurement for ships has increased. Traditional means such as telephone and fax to handle ever-increasing harbor transaction, however, has proved to be very time-consuming and cost ineffective. Therefore, people are starting to look for more effective ways. In this paper, an internet-based scheme of B2B transaction is proposed to handle procurement problem between shipping agency and shipping company, and between vessel and suppliers as a more effective approach to streamline such problems. We extract problems of shipping agency through task-analysis and present a scheme that performs decision making and procurement as a system agent with brokering structure. Purchaser and supplier are offered material information rapidly and task loads are minimized by the scheme. Also, the system can support decision making of purchasing goods, and information is shared among purchaser, supplier and system through the system interface.

날로 더욱 치열해지는 글로벌 경쟁환경 속에서 살아남기 위해 국제물류를 담당하는 해운기업들은 선사들간의 전략적 제휴, 자체 선대확보 및 서비스항로 확대 등을 통해 경쟁우위를 이루고자 힘쓰고 있다. 다시 말해 인수합병 또는 지속적인 투자를 통한 규모의 확대와 같은 서비스의 양적인 측면과 해운서비스품질 및 인적자원에 의한 고객서비스 향상 등 서비스의 질적인 측면을 강화하는 차별화된 해운서비스 제공을 위해 노력하고 있다. 따라서 본 연구의 목적은 조직-종업원-기업성과로 연결되는 이상과 같은 관계를 실증분석하여 정기선서비스를 제공하는 국적선사 및 외국적 선사의 지사나 대리점 등 해운기업이 경쟁력제고를 위해 각 요소들 간의 관계를 이해하고 이를 활용함으로써 효과적으로 경쟁우위를 점하기 위한 전략구상에 도움이 되고자 한다. 먼저 서비스지향성, 종업원 만족, 고객지향성, 기업성과 등에 관한 선행연구들과 해운서비스에 관한 선행연구를 토대로 정기선사에 적합한 개념들을 도출하고 측정도구를 개발하고, 이를 토대로 정기선사의 서비스지향성과 종업원의 직무만족과 조직몰입 그리고 고객지향성, 기업성과간의 관계에 대한 개념적 모형과 연구가설을 설정하였다. 연구가설을 검정하기 위해 정기선사를 대상으로 설문조사를 실시하였으며, SPSS ver. 12.0을 사용하여 수집된 자료를 분석하였다. 신뢰성 검정을 위해서는 크론바하(Cronbach)의 ${\alpha}$ 계수를 활용하였으며, 측정도구의 타당성을 검정하기 위해 요인분석을 이용하였고, 가설검정을 위하여 다중회귀분석을 실시하였다. 연구 결과는 다음과 같다. 정기선사의 서비스지향성은 종업원 만족에 정(+)의 영향을 미치는 주요한 요인이다. 또한 직무만족과 조직몰입을 통한 기업의 목표달성을 위한 종업원들의 헌신적인 태도에 영향을 미친다. 더불어 서비스지향성, 종업원 만족, 고객지향성과 기업성과 사이의 관계는 최종적으로 고객만족에 영향을 미치며 이러한 관계들은 기업의 성공적인 목표달성과 기업성과를 가져오는 주요한 원인이 될 것이다.

The analytical hierarchy process (AHP) enables decision makers to represent the interaction of multiple factors in complex and unstructured situations. The process requires the decision maker to develop a hierarchical structure of the factors in the given problem and to provide judgments about the relative importance of each of these factors and ultimately to specify a preference for each decision alternative with respect to each factor. The research presented in this paper applies the AHP to identify key players in promoting port competitiveness. The literature survey revealed four major criteria and 15 sub-criteria. The four factors are cost, service quality, facility/capacity and economic-social variable. 150 questionnaires suitable for AHP analysis were made and 77 were returned. It is found that in terms of cost, the first key player is terminal operator and the second key player is shipping companies calling Busan port; in terms of service quality, the first key player is terminal operator, and the second key player is shipping companies calling Busan port; in terms of facility/capacity, the first key player is port authority and the second key player is terminal operator; in terms of economic-social variable, the first key player is terminal operator, and the second key player is shipping companies calling Busan port.

It has been more recent trends in container trade to make bogger ship from shipowners that many more parties concerned are getting involved. Well, it is natural to swift these situations if we have looked into container trade market in present time, which a lot of trade volumes has increased in world economy. Thus, supply side of shipping service needs to employ more capacity in the shipping market, then newbuilding may be compulsory options, that is deployment of larger ships. To cope with market situations as able shipowner, some alternatives can be also adopted, such as newbuilding, chartering and securing the space by strategic alliance. But whatever he does, shipowner has to keep in mind to prepare for the future. This is much more important factor considered to make investment decision in case of newbuilding and then he can make more efficient decision as well. However, there has been a little problems arisen due to larger ship employed on the trade route, which is linked with seaport, shipping companies and freight rates as well. Although shipowner decides to build new larger vessel as one of corporate strategic decision, there are many questions to be considered in advance. Therefore, in order to take more efficient decision, shipowner has to take into an account various situations surrounded, and then it can lead truly thoughtful decision making process.
