Currently, there are very few papers that have examined the efficiency of Vietnamese ports. Of those that have, some of them take into account only a few container ports in Northern Vietnam. Others focus on comparing all types of ports in Vietnam with regard to the differences in efficiency scores when applying different methods to evaluate efficiency. However, there is no paper that specifically analyzes the efficiency of Vietnamese container ports throughout the country or that compares Vietnamese container ports with those of other countries in terms of efficiency. In order to provide more accurate and interesting information for container port authorities, in this study, 21 major Vietnamese container ports and seven major Korean container ports are selected and examined with regard to their levels of efficiency in 2016 using data envelopment analysis (DEA). This paper applies both constant return to scale (CRS) and variable return to scale (VRS) to explore the differences among overall technical efficiency, pure technical efficiency, and scale efficiency of the selected container ports. This study also indicate slacks and sets projections for inefficient ports.

The main purpose of this study is to design the port marketing strategies for strengthening the competitive power of container terminal. So far many attempts have been made to analyze the international competitiveness of the terminal. Six factors hypothesized by this study come from previous research analyses about customers preference for port selection. Those are Cost Centrality and Intermediacy Free trade port Inland transportation connections Political and Economic institution and Port facilities. this study analyzes the most important factors about hob port and transhipment port separately through questionnaire analysis about users(shipper shipping company and freight forwarder) influencing on port selection. The results of this study were found as follows:

The fact that Pyeongtaek Port is located ideally at the central point of the Yellow Sea's Economic Zone and it is very close to the metropolitan area of South Korea which occupies more than 50 percent of the total trade volume in terms of tonnage is providing a good prospect of development for the Port of Pyeongtaek. This study examines the perception of shippers in Kyonggi-do on the development of Pyeongtaek Port, giving some suggestions to the Pyeongtaek Port Authority. It begins with a description of the port such as current economic status, statistics on the economy, trade and investment regarding the Port of Pyeongtaek. According to a particular questionnaire survey conducted in December 2001, the major obstacles to the utilization of the port are as follows: a shortage of liner shipping routes, lack of container handling facilities including container terminal, crane etc., and port sales promotion activity. Therefore the port should make aggressive efforts to attract container cargoes to and from China by expanding port facilities, implementing effective marketing strategies, introducing a customs-free zone/free trade zone, and strengthening port sales etc.

The Port of Busan is currently ranked as the seventh largest container port worldwide in terms of cargo throughput. However, port competition in the Far-East region is fierce. The growth rate of container throughput handled by the port of Busan has recently slowed down. In this study, we analyzed how economic conditions and multiple external shocks could influence cargo throughput and identified potential implications for port business. The aim of this study was to build a model to accurately forecast port throughput using the ARIMA model, which could incorporate external socio-economic shocks, and the VEC model considering causal variables having long-term effects on transshipment cargo. Findings of this study suggest that there are three main areas affecting container throughput in the port of Busan, namely the Russia-Ukraine war, the increased competition for transshipment cargo of Chinese ports, and the weaker growth rate of the Korean economy. Based on the forecast, in order for the Port of the Port of Busan to continue to grow as a logistics hub in Northeast-Asia, policy intervention is necessary to diversify the demand for transshipment cargo and maximize benefits of planned infrastructural investments.

An application of the genetic algorithm(GA) to the loading sequencing problem in port container terminals is presented in this paper. The efficiency of loading operations in port container terminals is highly dependent on the loading sequence of export containers. In order to sequence the loading operation, we hove to determine the route of each container handling equipment (transfer crane or straddle carried in the yard during the loading operation. The route of a container handling equipment is determined in a way of minimizing the total container handling time. An encoding method is developed which keeps intermediate solutions feasible and speeds up the evolution process. We determine the sequence of each individual container which the container handling equipment picks up at each yard-bay as well as the visiting sequence of yard-bays of the equipment during the loading operation. A numerical experiment is carried out to evaluate the performance of the algorithm developed.

This paper deals with the case study that determine the best equipment scale to be satisfied a handing capacity of the container terminal using computer simulation techniques. The objective of this study is to suggest an operation alternative of equipment scale including container canes, transfer cranes, and yard tractors which reflects a container throughput. For the simulation, the object-oriented simulator with the special purpose of container terminal analysis is used. And the used simulator was developed to simulate the transfer crane based container terminal for yard equipment. Using the simulator, we test an existing port container terminal, PECT(Pusan East Container Terminal).

각 항만의 터미널별 물동량을 기반으로 허쉬만-허핀달지수를 통해 부산항과 상하이항의 시장구조 측정을 실시하였고, 시장성과를 분석하기 위해 시장성과를 수익성과 성장성의 두 가지 측면으로 구분하였다. 수익성 측면에서는 각 컨테이너 터미널 운영사들의 가격-비용 마진율(PCM)과 자산수익률(ROA), 성장성 측면에서는 각 터미널의 처리 실적과 물동량 증감률을 통해 각 터미널 운영사의 성과를 측정하였다. 측정된 결과를 바탕으로 시장구조와 터미널 운영사의 성과에 대한 상관관계를 살펴보기 위해 회귀분석을 실시하였고, 결과를 상호 비교하였다. 연구결과, 부산항의 시장구조와 컨테이너 터미널 운영사의 성장성(처리실적), 상하이항의 시장구조와 컨테이너 터미널 운영사의 수익성(PCM, ROA) 및 성장성(처리실적)과의 관계가 유의적인 관계로 나타났다.

컨테이너 처리량(CHC)은 항만의 능력을 나타내는 중요한 지표다. 그러나 중국항만의 컨테이너 처리능력에 대한 연구는 부족하며, 연구결과 또한 예측치와 실제치와의 차이가 크다. 이는 컨테이너처리량이 다양한 경제적인 측면을 내포하고 있고 예측모델의 선택이 매우 어렵다는데 기인한다. 대체로 지금까지 사용되어왔던 회귀분석, 신경망분석 등은 과거행태모델을 벗어나지 못하고 있어 경제체제나 항만물동량의 동태적변화에 대한 고려가 결여되어 있다. 따라서 본 논문에서는 동태적 보정인과모델을 사용한 동태적 예측법을 사용해 보았고 그 결과 보다 신뢰성이 높고 현실성이 있는 연구결과를 도출할 수 있었다.
