The advent of the 4th industrial technology brought about various changes and innovations in the overall industry, but the digitalization of the logistics industry, which involved complicated paperwork processes and various stakeholders, was somewhat behind compared to other industries. However, changes and innovations related to digitalization in the logistics industry began to accelerate due to the impact of COVID-19. This study is to check the digitalization status of container liners accelerated by these changes, analyze the impact of such changes on customer satisfaction and behavioral intention. In this study, a questionnaire survey was conducted for 30 days targeting workers in the logistics industry who had experience using digitalization products of container shipping companies, and a total of 144 questionnaire responses were used to verify hypotheses. To summarize the results of this study, first, it was confirmed that perceived ease of use has a positive (+) effect on perceived usefulness. Second, perceived ease of use was found to have a positive (+) effect on customer satisfaction. Third, it was found that perceived usefulness had a positive (+) effect on customer satisfaction. Fourth, perceived usefulness has a positive (+) effect on behavioral intention. Fifth, it was found that customer satisfaction had a positive (+) effect on behavioral intention. Summarizing the results of the study, it can be summarized that the digitization of regular shipping companies is convenient to use and has a positive effect on customer satisfaction and behavioral intention if it is useful.

This paper suggested an efficient mathematical model for strategic alliance of liner shipping companies. Even though a few previous research papers proposed the mathematical models for container slot chartering and allocation under liner shipping, those models were nonlinear and very difficult to solve. So their models had limits to apply them to real world problems. On the other hand, the model suggested in this paper is easy to solve and apply to real world problems because it is a integer linear programming model. This paper tried to apply the model to the same example problem as used in existing research paper. Excel add-in program, Premium Solver Platform was used to solve the problem and the optimal allocation and slot chartering for containers were able to be found easily. The result also showed that the total container shipping cost for applying the strategic alliance model was reduced compared to non-strategic alliance model.

Under the rapid change of the world shipping industry, the liner shipping company in Korea should initiate the adaptation power, counterplot for survival, and continuous development. The world shipping industry is in the middle of the wave for the liberalization and openness of it. According to this change in world shipping industry, it is the fact that government policy for shipping industry should start turning its direction from the protectionism to the liberalism. Under this kinds of situations, this study firstly treated the liner shipping company and its governmental policy of Korea and Japan. Based on those studies, analysis of the liner shipping company operation and management reality was executed. Through the execution of studies, the problems which should be solved for development occurred. Furthermore, this thesis takes two way of researches of literature and actual proof for reinforcement plan of international competitiveness. This standard time period of study is set in 1993 except the irregular liner shipping company.

Determination the optimal containership size is the most important factor for competitiveness if shipping companies. Accordingly, the objective if this research is determining the optimal containership size by service routes. Total shipping cost is calculated at the ground if capital cost, vessel operation costs, voyage costs, port charge and miscellaneous cost for 'Europe-Far East', 'Far East-North America' and 'Europe-Far East-North America' Services. Finally, the optimal containership size was utilized through total shipping cost, slot quantity if containership and average throughput by containership.

To induce container cargos to Gunsan port, we should struggle on securing the quantity of goods transported from the competitive Jeonbuk and Chungcheong areas by reducing transportation expenses by land, and make an activating plan for the international exchange between Gunsan port and nearby ports in China. As a result, if the plan to induce container cargos to Gunsan port is activated, the regular liners will stop at Gusan port. So the new sea route will be opened so that consignors can ship cargos in the proper time. The consignors will use Gunsan port frequently because of the reduction of distribution expenses. To do so, for the first, many incentives should be implemented to attract container cargos. In addition, various facilities should be fully equipped and improved. This paper is to improve the problems for which consignors, the shipping lines and forwarders may feel uncomfortable when they use Gunsan port. According to the research on the actual condition, the biggest problem in Gunsan port is the depth of water. The management, relation system, infrastructure and information system of Gunsan port are also insufficient. Therefore, this paper will make an alternative plan to improve these problems and help the container cargos induce to Gunsan port.

This study attempts to establish a precise forecast model for the container inventory demand of shipping companies through forecasts based on equipment type/size, ports, and weekly system dynamics. The forecast subjects were Shanghai and Yantian Ports. Only dry containers (20, 40) and high cubes (40) were used as the subject container inventory in this study due to their large demand and valid data computation. The simulation period was from 2011 to 2017 and weekly data were used, applying the actual data frequency among shipping companies. The results of the model accuracy test obtained through an application of Mean Absolute Percentage Error (MAPE) verified that the forecast model for dry 40' demand, dry 40' high cube demand, dry 20' supply, dry 40' supply, and dry 40' high cube supply in Shanghai Port provided an accurate prediction, with $0%{\leq}MAPE{\leq}10%$. The forecast model for supply and demand in Shanghai Port was otherwise verified to have relatively high prediction power, with $10%{\leq}MAPE{\leq}20%$. The forecast model for dry 40' high cube demand and dry 20' supply in Yantian Port was accurate, with $0%{\leq}MAPE{\leq}10%$. The forecast model for supply and demand in Yantian Port was generally verified to have relatively high prediction power, with $10%{\leq}MAPE{\leq}20%$. The forecast model in this study also had relatively high accuracy when compared with the actueal data managed in shipping companies.

The port industry is an important national industry which significantly affects Korea's imports and exports which are centered on economic structure. For instance, the Port of Busan, which handles 75% of domestic container freight volume, is expected to become increasingly critical for container liner routes. For this reason, there have been continued efforts to expand freight service to attract international freight volume. This study analyzes the structural characteristics of the port network connected to the Port of Busan by analyzing the pattern of the container liner route from 2012 to 2016 by using social network analysis. According to the Port of Busan's liner route network, the port with the highest degree of centrality, closeness centrality, and betweenness centrality was found to be the Port of Singapore. The comparison of Busan's annual container handling rank by countries and the port center network analysis of Port of Busan rank was found to be different. As a result, it was established that China's East Port, which occupies a high percentage of the volume of cargo handled by Port of Busan, is not a hub port of Busan when viewed on the Busan's container terminal liner network. In addition, even if the number of Port of Busan container liner service increases, it is estimated that the vessels to be added to the fleet will be limited to small to medium sized, or that Busan port has characteristic of a feeder port for the Port of Singapore, according to the network.
