The aim of this study is to select the import and export goods which contribute to activate the operation of port hinterland. The spatial ranges of this study are A-am 1 logistics complex and 4dock hinterland. The Factor Analysis(FA) and Analytic Hierarchy Process(AHP) are used as the methodologies. Eleven low evaluation factors including 'creation of traffic cargo volume' are selected by precedent studies and four high evaluation factors including 'effective management' are grouped through factor analysis. As the result of priority among low evaluation factors through AHP, 'creation of traffic cargo volume' is the most important factor. Moreover using the AHP, 'electronic component' is the most important item which activate the Port of Incheon and its hinterland. So cargos which have the potential to create traffic cargo volume such as 'electronic component' must be managed strategically and this study can be used as important index when people concerned attract items.

It is important to adopt an operation system to operate the Automated warehouses using limited resources such as space, mobile racks, and forklift. The main purpose from the operation system is to reduce the length of moving and time for both mobile racks and forklift. The complexity of the warehouse will be higher because the racks and vehicles are moving at the same time. This complexity influences badly so the operation system has to control it well. Not only layout or receipt or issue, but also conflict between mobile racks and vehicles give more complexity to the warehouse. This paper aims to fine the proper operation method related to the layout and the cargo assignment.

As international trade has been increased, the competition of major ports is getting hard. The objective of this competition is that to get more cargoes, so port managements and operators are struggling to obtain cargoes. In addition the competition structure has classified several forms bemuse of specialization, integration and subdivision of port players. In this paper, therefore, we analyze the change of competition structure by port players' development characteristics. In the result of this study, competition structure is divided into five groups as among nations, among ports, among container terminal operation companies, among global container terminal operation companies and among container terminal operation companies operated by shipping companies. And they have showed not only competition but also co-operation partly in order to get strategic position.

As discussions of the International Maritime Organization for the introduction of the Marine Autonomous Surface Ship (MASS) began in earnest, discussions were conducted to prioritize cybersecurity (Cyber Risk Management) when developing a system to support MASS operation at the 27th ENAV Committee Working Group (WG2). Korea launched a technology development project for autonomous ships in 2020, and has been promoting detailed tasks for cybersecurity technology development since 2021. MASS operation in a digital maritime communication system environment requires network security of various digital equipment that was not considered in the existing maritime communication environment. This study introduces the basic concept of network security equipment to support MASS operation in the detailed task of cybersecurity technology development, and defines the network security equipment interface for MASS ship application in the basic stage.

Recently, container terminal managers make an experiment on the double cycle and dual cycle operation, which ship loading and unloading were carried out simultaneously, for increasing the productivity of quay side. If, however, we make an experiment on dual cycle operation in a real job site, the efficiency is poor up to terminal operation method as YTs(Yard Tractors)' allocation method, QCs(Quay Cranes)' working speed, and position of export containers. Especially, using the existing yard operation method, it is difficult to support to dual and double cycle operation. Therefore, this paper examine more efficient terminal operation method, when terminal uses dual cycle operation. We developed a simulation model using simulation analysis software, Arena.

Recently it has become easier to figure out cargo positional information by using GPS(Global Positioning System) and wireless communication technology. The acceleration of globalization in the shipping logistics is ever more increasing the need to provide visibility, traceability and real time informations of entry, departure of vessel including cargo and status of logistic vehicle entry into each logistic base. Providing such positional information to logistics party by using wireless communication technology can bring effective operation of supply chain and reduction in logistics costs. In the previous paper, I suggested a global location tracking system based on GPS data in global shipping logistics by means of software using GPS data. However, the previous system had a problem of being inadequate to figure out a real time location movement information and was unsatisfactory on quickly searching and checking the location of global logistics hubs according to the longitude and latitude coordinates. Hence, in this paper, I suggest a real-time location tracking system that provided real-time location of the container cargos and logistics hubs can be searched quickly according to the GPS coordinates in global shipping logistics.

Due to the changes in the distribution market, issues related to storage and distribution of agricultural, aquatic and livestock products, and storage and transportation of processed and fresh food are rapidly emerging, and as a result, Cold Chain is naturally receiving attention as one of the logistics services. The purpose of this study is to evaluate the competitiveness of location in the construction of a cold chain cluster centered on the metropolitan area, which has attracted attention in relation to the distribution of cold chains, such as recently refrigerated frozen foods. To this end, this study evaluated the competitiveness of cold chain cluster candidates in the metropolitan area by utilizing the CFPR (Consistent Fuzzy Preference Relations) method that can efficiently extract and quantify expert knowledge. As a result, the location competitiveness was found to be superior to Incheon New Port's hinterland, Gyeonggi South Area (Yongin), Gyeonggi West Area (Gimpo Logistics Complex), and Pyeongtaek Oseong Logistics Complex. In particular, this study extracted the knowledge of refrigerated and refrigerated logistics warehouse operation experts, and conducted detailed competitiveness assessments for cold chain cluster candidates in the metropolitan area, and suggested the optimal cluster candidates. In the future research, it is necessary to classify the questionnaire into the owner, large business group, and public business group, etc., who have the right to purchase and build to secure ownership of the fresh food distribution center.

This study estimated the regional economic effects by development of the logistics complex in Incheon New Port, applying the regional Input-Output tables in Incheon. And thereby, we tried to find some strategic implications on the priority to induce more effective industries for activated operation of the logistics complex in ports. According to the results, development of Incheon New Port will generate 2,579 billion KRWs(2.2 billion USDs) of production and 1,783 KRWs(1.5 billion USDs) of value-added annually. And we expect it to induce 38.8 thousand jobs, which is over the national average on the input-output table. By the business type, port logistics industry will contribute to develop regional economy more than any other ones in Incheon. We suggest business firms in port logistics industry to be induced to the logistics complex in Incheon New Port strategically. Until now, development of the logistics complex in Incheon New Port are planned to be postponed to 2015 when construction of the berth facilities, the access sea routes and the hinterland highways are completed. We suggest to invest more public fund, to induce the private capital, and then, to develop the logistics complex in Incheon New Port earlier in an appropriate scale.

Purpose - This paper evaluated the efficiency performance of the three major maritime transport markets and examined the determinants of the performance. The firms' revenue fluctuates with the changes of the economic cycle; hence it is important for them to set up business strategies to improve efficiencies. A lack of efficiency measurements for shipping firms leads to a significant gap in determining their overall performance. Research design, data, and methodology - Each of DEA scores was adopted for the evaluation and panel regression was used to examine the impact of determinants on the performance. The analysis included 50 shipping firms from three maritime transport markets as follows; 15 firms of container liners, 18 firms of bulk carrier and 17 firms of tanker carriers, and its period was from 2010 to 2016. Results - In the CCR model, container liners were the highest, tanker carriers were the second, and bulk carriers were the lowest in operation efficiency and financial efficiency. By region, operation efficiency and financial efficiency was high in the order of America, Asia, and Europe. Conclusions - This study suggests business strategies for maritime transport companies based on the analytical results of determinants of operational and financial efficiency.
