Recently, brand equity is paid much attention in various industries. However, container liner shipping companies are still unfamiliar with this concept, and also the brand equity model has not been tested yet in shipping context. This study, therefore, aims to measure the relative importance of brand equity factors of container liner shipping companies by employing AHP (Analytic Hierarchy Process). This study concludes that perceived quality, in particular cost-related service quality, is the most influential factor of brand equity, while weak support is found for brand association. In addition to this, group comparisons were conducted between shipping companies, freight forwarders and academics. The results will be useful as they firstly define brand equity and its role in shipping context, highlighting the significance of brand management to container liner shipping firms. This evaluation is not an end in itself, but will eventually be utilised as a tool to build competitive advantage which cannot be easily imitated by competitors.

As the competition in the liner shipping industry is becoming fiercer, the shipping company is trying to find the way to keep the best competitive position by reducing the cost level as low as possible and offering the best quality of service to their customer. In order to achieve this goal, the selection of port and terminal that have the best quality of service and cost effective structure is essential for the shipping line, where they can only have a chance to save the money. In this context, the paper compares three European container terminals in order to understand the factors that have to be considered in the decision making process for the selection of terminal. And its advantages and disadvantages of each type of container terminal operation system were analyzed from the liner shipping company's point of view in terms of cost, time, flexibility, stability, hinterland connection, geographical position and terminal productivity. It is obvious that the cost factors are very important for liner shipping company to select their terminal. However, there might be even more important factors than the cost factors, such as quality of port and terminal service, mutual trust, and possibility of future development.

For container shipping company, fuel oil prise is a considerable expense. Since 2008, fuel oil prises have risen dramatically. An increasing fuel oil price in container shipping, in the short term, is only partially compensated through surcharges and may affect earnings negatively. This study discusses the impact of an increasing fuel oil price and capital costs for vessels on the Asia-Europe trade of 'H' Shipping Company. According to the result of 'H' carrier's operation in 2008, there were no cost differences between 8 and 9 vessels operations in case of fuel oil price with USD 169/tons while adopting USD 31,818 as a fixed cost. We can expect that the fuel oil price will not go lower than USD 200/Ton on the basis of current high oil price phenomenon. When the fuel oil price is over USD 200/ton, 9 vessel operation is more economic than 8 vessel operation even if the fixed cost is over USD 35,000.

From the beginning of 1990s , also in the shipping industry, especially liner shipping industry competition has been more intensive and difference of the service quality among shipping companies has been learned . On the other hand, a shipping company has some limitations to do its international mission for itself just by broadening service area. For this reason, the necessity for the global strategi alliance among the shipping companies, which is orginally aimed at sharing of facilities and organixation, has been developed. Through strategic alliance, liner shipping companies do not need to input the additional capitals to increase the material assets such as vessel capacity and spread the risk by the enlargement of the market. Also, they can secure the competitive edge through efficient utilizaton of assets. The purpose of strategic alliance of Hanjin Shipping Ltd., can be summarized as follows ; broadening of service area, cost reduction through vessel sharing, realization of rationalized shipping service by terminal and equipment or facilities sharing. Liner strategic alliances are agreement among liner companies to pol their equipment , andterminals for joint operations and services in which each alliance partner continues to serve its market using jointly operated or used inland feeders,inland terminals, port terminals, and mainline fleets of ship as well as joint pools of containers and equipment. Strategic alliances are generally more formal agreements than consortia and impose longer term and far reaching obligation on their members. It also acts as one in developing and advancing the strategic aims of the alliance members. The most important objective for liner strategic alliances is cost reduction and improvement in capital asset utilization. Main aims of strategic alliance drawn in this paper, can be enumerated follows : 1. improvements in service frequency and quality : 2. improvements in vessel and equipment utilization and thereby reductions in fixed and variable cost ; 3. improvements in market shares and high value cargo booking ; 4. reductions in intermodal storage and port terminal throughput costs ; 5. improvements in negotiating powers with ports and feeder transport providers ; 6. reduction in financial and other fixed costs such as insurance; 7. coordination and integration of MIS and EDI systems and service for greater efficiency and market penetration ; and, 8. improvements in logistic chain management and economic of scale by equipment depot, terminal, and vessel sharing.

본 연구는 부산항과 인천항간 컨테이너 연안운송이 중단된 배경을 비용구조와 수입 배분의 특성, 시장에서 기업의 행동상 제약으로 구분하여 살펴보았다. 이를 위해 연안운송의 국내물류체계와 연관된 선박 운영비용의 구조를 고찰하고 비용함수를 추정하였다. 또한 연안선사내 운영수입의 배분비율을 살펴보았으며, 144TEU급과 215TEU 급 선박의 평균수입을 산정하였다. 경제적 제약 측면에서는 기업의 이윤 극대화 혹은 손실 최소화라는 목표를 전제로, 연안운송의 중단 원인을 찾으려 노력하였다. 연구 결과, 연안운송은 운영비용 측면에서 최대적재능력에 가까운 적재율을 실현하고 대형선박을 투입할 경우 규모의 경제를 실현할 수 있었다. 운영수입에서는 트럭운송시장의 영향, 복잡한 물류체계에 따른 낮은 평균수입으로 적자가 누적될 가능성이 있었다. 경제적으로는 평균수입이 평균비용보다 낮아, 연안선사가 서비스를 중단하였던 것으로 판단되었다. 따라서 전용선박에 의한 연안운송이 지속되려면 정부 등의 보조금 지원이 필요하다고 판단된다.

연료유 비용은 컨테이너 해운 선사에 있어 상당한 비용을 차지한다. 지난 3년 간, 연료유 가격은 상당하게 증가하여 왔다. 컨테이너 해운에서 단기간에 계속적으로 증가하는 연료유 가격의 일부만이 운임애 대한 할증료를 통해서 보완되고 있다. 따라서 수익(earnings)에는 상당한 부정적인 영향을 주게 된다. 본 연구에서는 H선사의 AEX 항로에 대한 유가 및 선박 관련 자본비용에 대한 경제성 분석을 하였다. H선사의 2008년 DAYLY 척당 평균 고정비 31,818 USD 적용 시 연료유 가격이 169.35$/TON 일 때 8척 운항과 9척 운항의 항차당 운영비용이 동일하였다. 현제의 고유가 상황을 고려할 때 연료유 가격이 200$/TON이하로 형성되기 어려울 것으로 예상된다. 따라서 200$/TON이상 일 때 고정비(용선료)가 35,000$이 넘어서더라도 8척 운항 시 보다 9척 운항이 경제성이 있는 것으로 분석되었다.

Container terminals at Gwangyang Port are operated by three container operators: A, B and C. Ultimately, there is consensus that a single operator should operate all terminals so that economies of scale can be achieved even in the operation of the container terminal. Integration between operators has a positive effect on both operators and shipping companies. From the operator's point of view, overlapping fixed costs between operators can be unified, reducing overall costs and utilizing spare facilities. On the other hand, from the viewpoint of the shipping company, it is possible to ensure stable use of the port facilities and always allow berthing, reduce days on demurrage and ship waiting, and provide one-stop service for work. However, existing cases of operators' integration or relocation of terminals remained to estimate the expected effects of alternatives, emphasizing only the financial point of view. The port terminal is a large system, and it is important to consider that it is an aggregate of major logistics facilities and equipment. Moreover, if the estimation can be made by quantifying the expected effect, the justification of the terminals' relocation can be further emphasized. Therefore, it is very important to estimate the expected effect from the viewpoint of systemic operation. Moreover, the need for operators' integration can be further emphasized if it can be estimated through quantification of expected effects. Currently, three alternatives are considered as alternatives to the terminals' relocation, and in this study, the optimal plan was derived for the 3 alternatives by the linear planning model of the minimum shuttle transportation cost in the terminal. The optimal plan is alternative 2, which shows the most advantageous integration effect in terms of expected effects. Alternative 2 integrates the B terminal into the C terminal, and the A terminal operates independently as it is.
