Port operational efficiency is considered as one of the most important competitive factors and plays a critical role in the port development all over the world, especially container ports. Haiphong Port, which is in the northern of Vietnam, is planned to become one of the national and regional ports. To do this objective, it is important to analyse the operational efficiency of its container terminals. The paper aims to comparatively analyse the operational efficiency of 16 container terminals in Haiphong Port from 2016 to 2022 by basic and Malmquist DEA models. With 112 observations collected and calculated in R software, DEA models have five inputs (container yard area, number of quay crane, berth draft, berth length, labour force) and one output (annual cargo throughput). Consequently, Hai An, Tan Vu, and Vip Greenport are more efficient terminals over the 7-year period, whereas Transvina and MIPEC have lower efficiency. Paper contributions are the literature review about port operational efficiency and references to propose resolutions in next author’s research as well as masterplans to develop Vietnam seaport’s system. Besides, the limitations are discussed as the number of observations and environmental factors in ports.

Along the 3,200km-long coastline, Vietnam has a significant number of seaports, which are relatively large and named as the keys to economic development. However, most ports are relatively small with obsolete facilities and poor supporting services. Among three largest ports countrywide, Ho Chi Minh City seaport has had the highest throughput and productivity per annum of the country for years, assumed the role of the major port in the south, where cargos and containers come and go from all industrial parks in the southern region. Situated on what was the outskirts but is now the outskirts or suburbs of Ho Chi Minh City, it has however shown some drawbacks, i.e., expansion of the port is not an option regardless of the high throughput. Apart from the inadequate infrastructure, ports are facing another setback due to backward pricing. The rapid increase in number of ports also created a “race to the bottom” situation, where Vietnam ports have reduced their price to attract customers. The direct results are lower service quality and an inability to reinvest into port development. Therefore, the restructuring of Ho Chi Minh City seaport system has been launched since 2006 whereby the plan not only resolves the limited size, obsolete facilities and traffic issues, but also becomes more efficient as the new port complex is located conveniently among the region’s industrial parks and export processing zones of Ho Chi Minh City, Binh Duong, Dong Nai, and Ba Ria – Vung Tau. In line with this plan, the paper will mainly aim to provide the outstanding constraints which Ho Chi Minh City seaport system faced, including illogical distribution among ports/terminals regardless the scale, capacity and geographic locations; ineffective and insecured mooring and anchorage buoys; undeveloped logistic services centres and lack of connecting infrastructure. As so, the recommendations for single issue will be provided.

본 연구는 3개의 투입변수와 3개의 산출변수로 구성된 DEA법을 이용하여 우리나라 항만의 노무효율성을 측정 평가하였다. 대상항만의 전체 기술적 효율성은 평균 94.18% 수준이었으며, 순수 기술적 효율성은 100%로 나타났고 규모의 효율성은 94.18%로 전체 기술적 비효율성이 가장 높게 나타났다. 분석결과 7개의 항만은 효율적인 항만으로 측정되었고 4개의 항만은 비효율적 항만으로 측정되었다. 4개의 비효율적 항만중 규모에 대한 수익체증은 동해항으로 나타났다. 그러나 비효율적인 항만들은 생산규모의 비효율성보다 자원운영의 비효율성이 높은 것으로 나타났다. 한편 초효율법을 이용하여 효율적인 항만의 우선순위를 분석한 결과 인천항, 목포항, 평택당진항, 마산항, 여수광양항, 제주항, 군산대산항 순으로 효율성이 높은 것으로 나타났다. 특히 비효율적인 부산항은 목포항 및 인천항을 벤치마킹하여 항만 물동량의 증대, 장비의 현대화 및 노무효율성의 향상을 위해 전면적인 노무상용화가 필요하다.

The need for improved port call performance in African ports is way overdue as none of the African sea ports appear on the top 100 sea ports in the World as presented by the Lloyds list. The performance of ports greatly serves and benefits various stakeholders besides the country in which they belong. These stakeholders do include but not limited to third-party logistics providers, vessel/ship owners etc hence the need to improve port call performance is critical. There is not much studies available that tackle the issue of port call performance a hence creating a gap which this study opted to fill and contribute towards the assessment of Africa maritime trade contributors port call performance as most of the ports in Africa are deemed not efficient. Hence this analysis aimed at analyzing the performance of African top ten leading countries that contribute to the global maritime trade and later combine both African countries and the world’s top ten leading maritime trading countries as a benchmark to establish an improvement strategy from which low performing DMUs in the analysis were to borrow a leaf from. Having conducted the study, some African countries came out to be more performing. A few adjustments are to be made for them to improve their port call performance. However, their performance was still above average in comparison to the world’s leading countries that posed as benchmark and a standard port call performance operation strategy.

The efficiency of port operations is an important indicator of port development. Moreover, there is excess handling capacity in Chinese ports, which results in a slower speed of development. Under the detrimental environment of the international shipping market, it is necessary to improve the operation efficiency of ports for long-term development. This paper provides an assessment of the competitiveness of Chinese seaport companies using the Boston Consulting Group’s matrix, and efficiency measurements using a data envelopment analysis and the Malmquist method. This analysis showed that highly efficient companies reformed their development strategies, which should be a solution considered by less efficient companies, such as Shenzhen Yan Tian Port Holdings Co., Ltd.. Although, having high throughput should be reformed in the investment structure. This research will assist port companies in gaining effective operating experience, and governments in establishing strategic planning to enhance the efficiency of port development.

본 연구는 항만 물류배후단지에 입주하여 운영하는 입주업체들의 효율성을 분석하는 것을 연구의 목적으로 하였다. 인천항과 부산신항 항만 물류배후단지 13개 입주기업을 효율성 분석대상으로 하였으며, 투입변수는 투자액, 면적, 종업원 수를 사용하였고, 산출변수 는 물동량과 매출액을 선정하였다. 효율성 분석방법으로는 전통적인 CCR 모형과 BCC 모형을 적용하고 이들의 한계점을 극복하기 위해 초효율성 모형과 Super-SBM 모형을 적용하였다. 초효율성 모형의 분석결과, 평균값은 0.777, 표준편차는 0.541로 나타나 각 기업 간 효율 성 점수 차이는 33% 정도 존재하는 것으로 분석되었다. Super-SBM 모형의 분석결과, 평균값은 0.649, 표준편차는 0.489로 초효율성 모형 에서 여분을 고려할 경우 기업 간 효율성 점수 평균이 약 13% 정도 감소한 것으로 나타났다. 이러한 감소의 의미는 비방사형 여분이 존재 하는 DMU의 효율성 점수하락이 평균 13% 정도 됨을 의미한다. 투입요소의 비효율성 분석결과 면적 -33%, 투자액 -33%에 비해 종업원 수의 비효율성이 -45%로 가장 큰 것으로 분석되었다.

Recently, the fierce competitions in the shipping industry and the global economic downturn have heavily influenced ports’ operational strategies. In order for port authorities to remain competitive at an international level and to provide more accurate information to develop National policies, ports are required to analyse and improve operations’ efficiency. In this paper, the efficiency of 19 Italian ports in 2013, handling different types of cargoes, is assessed through the application of Data Envelopment Analysis (DEA), with constant return to scale (CRS) and variable return to scale (VRS). The purpose of this study is to analyze the efficiency of Italian ports and evaluate whether differences in size and specialization of each port (or cargo handled) are directly correlated with ports' efficiency.

With the fast development Growth of Chinese economy is towing the world economy, and the world economy's initiative gradually moves to Asia, the economy of this region is growing fast. In addition, since over 90% of the international trade are made through marine transport, the volume of trade shows a continuously increasing trend with its growth. Qingdao established a bonded area in 1992 and a bonded port zone in 2008. Through 20 years' development, it has achieved very large achievements and has good conditions of the construction of an international hub port as a bridgehead toward the Eurasian Continent. Considering this situation, this study limits its spatial scope to Qingdao Bonded Port and Shanghai Free Trade Area, which are called the center port of China's free trade areas and conducts a comparative analysis of the competitiveness of Qingdao Bonded Port through efficiency indicators. Based on these various situations, this study will look into efficiency and development strategy for Qingdao Bonded Port .

In order to improve the overall ASEAN maritime transport network, each port's efficiency is regarded as a crucial factor that should be calculated periodically. This study evaluated the relative efficiency of container port operations of 32 ports belonging to 9 ASEAN nations using Data Envelopment Analysis (DEA). It found that 2 out of 32 ports in 2010 were measured as efficient ports. This study yielded two major findings. Firstly, the ports assessed as inefficient need to benchmark similar ports in size and structure from the ports that are assessed as efficient to improve their efficiency. Secondly, these results could be used to determine potential candidates and country for an international port development co-operation programme with Korea to improve the performance of the entire ASEAN port network by developing the infrastructures of ill-equipped ports.

비선형 시스템의 제어를 위해서 일반적으로 사용하는 하나의 동작점에서 얻은 선형모델에 기초한 제어기는 여러 가지 선형제어기법을 응용할 수 있다는 장점이 있지만 파라미터 변동에 대해 적절히 대처하지 못하는 단점을 가진다. 따라서 본 논문에서는 제어대상의 시스템 파라미터가 변동하는 경우에도 제어기가 적응적으로 작동하기 위한 방법으로 보간-LQ 제어기법을 제안한다. 보간-LQ 제어기는 다수개의 서브-LQ 제어기를 설계하고, 이들의 이득을 다시 보간하는 방법을 사용하기 때문에 파라미터 변동에 따라 제어기의 이득이 지속적으로 조정되는 제어기이다. 제안한 방법은 파라미터 변동이 존재하는 컨테이너 크레인 시스템에 적용하여 유효성을 살펴본다.

본 연구에서는 국내 컨테이너 전용 터미널(부산항 8개 터미널, 광양항 6개 터미널)을 대상으로 DEA(Data Envelopment Analysis) 모형을 통해 효율성을 분석하였다. 일정 시점을 대상으로 한 분석이 아니라, 1998년~2005년 동안의 효율성 분석을 실시하였으며, 이를 통해 각 터미널의 효율성 변화를 살펴보았다. 본 논문의 분석 결과는 우리나라 터미널의 상대적인 효율성 값을 제시해 줄 뿐만 아니라 신규 터미널 생성, 운영사의 변화, 터미널의 통합 운영 등에 따른 터미널 생산성의 변화 등을 제시하여 줌으로써 터미널 운영사의 향후 운영전략에 시사점을 제공하고 있다.
