Amid of the logistics hub center competition is going to intensifying between the world major port, it is essential to pre-occupied the base in the logistics hub world take advantage of advanced technology of logistics equipment than other ports. In existing container terminal, when container moves the terminal use the omnidirectional and directional antenna in order to exchange data information on the basis of 802.11 wireless network system. Case of loading height of exceeding, the blind sport will occur and a limited frequency channel can't help using in the area. A limited frequency channel usage and nested areas happen to use the closed terminal, it has a great influence to operate the terminal working. In this paper, LTE network is configured provided by the specified company ('L' Corp,.Ltd) and terminal data extracted through LBO (Local Breakout) in the cell site which is configured directly with container terminal operation server. Using this method, container terminal yard equipment operate without overlapping arises with uninterrupted data presented for ways to efficiently. I would suggest both the existing wireless AP LAN configuration of container terminal and new LTE system and applied to the real yard operating devices situations. Through these methods presented comparative the existing network traffic with new constructed LTE configuration. I admired to suggest that wireless network LTE introduction is fundamental factors to get rid of the blind spot, the problem of limited frequency channel and overlapping arises. These essential points can be a continual improving terminal services and more efficient terminal operational management.

컨테이너 크레인은 대형구조물로써 차폐물이 거의 없는 항만에 설치되므로 풍하중에 의한 영향이 매우 크다. 또한 초대형 컨테이너선의 등장과 대형선사의 등장과 함께 항만하역장비도 대형화, 고속화, 자동화됨으로써 컨테이너 크레인에 작용되는 풍하중의 영향이 더욱 증가하고 있다. 이로 인하여 컨테이너 크레인은 강풍에 의한 재난사고 발생위험이 항상 존재한다. 이러한 사고를 예방하기 위한 기상 및 하중 통합 모니터링 시스템 장치의 개발이 필요하며, 이러한 장치를 개발하게 되면, 국내외 기존 항만에 사용되고 있는 하역장비에 바로 설치할 수 있으며, 차후 개발되고 있는 자동화된 하역장비에도 적용이 가능함에 따라 관련 산업의 발전에 크게 기여할 수 있을 것이다. 본 논문에서는 이러한 하중 통합 모니터링 시스템의 가장 기본이 되는 컨테이너 크레인의 각 레그(Leg)부분에 부착되는 간접부착식 로드셀의 하중과 치수사이의 관계에 대한 연구를 제시하고자 한다.

In the current container port, the containers standardized by the automated operating system using the latest information and communication technology are systematically made according to the optimal stowage planning. However, loading of steel coils with a unit weight of several tens of tons is still performed manually, which is very inefficient. As a result, work is delayed and safety accidents occur frequently. In this study, an automated simulation system for loading steel coils was designed to prevent misjudgment, congestion, and safety accidents that occur during the manual loading process of steel coils.

Construction of automated terminal is urgently demanded to gain the foundation of hub-port in north east Asia. Therefore I suggest an adequate operating system model of automated terminal in Korea. In this paper the aim of automated terminal operating system is satisfied, four basic models are divided according to moving course of export and import cargo of each automated equipments, several input data are changed and analyzed dynamically by Trial and Error method, and then an optimized operating system model is designed. It is a Premise that all the yard equipments described in this paper must be automatic except quay crane.

Overseas advanced ports are promoting smartification, as well as full automation of the terminals surrounding container terminals. A smart port can be defined as a comprehensive concept that pursues increased operational efficiencies, maximization of profit, efficient use of energy, and construction of eco-friendly ports with the introduction of fourth-industrial-revolution technology, including port automation. However, Korea is making efforts to introduce fourth-industrial-revolution technology into ports, but indications are that they are somewhat insufficient compared to advanced ports abroad. Therefore, this study conducted a survey about operators and users of container terminals in Gwangyang Port by deriving the factors determining the introduction of smart ports, such as cost, service, time, safety, and environment, from previous studies. This study analyzed the factors determining the introduction of smart ports and moderating effects when the adjustment variables of operators and users were applied to the pros and cons. As a result of the analysis, it was found that port operators and users have a moderating effect on cost, time, safety, and environmental factors, but not on service factors. These results indicate that port operators try to reduce costs through efficient operation, time management, and by reducing safety accidents by building smart ports, but analysis showed that the negative effects of smart ports have affected port users. The results of this study were derived through a moderated regression analysis and suggested implications for introducing smart ports in the conclusion.

Significant increase of container flows in marine terminals requires more efficient automatic port systems. This paper presents a novel routing and collision avoidance algorithm of linear motor based shuttle cars using random access sequence dynamic programming (RAS DP). The proposed RAS DP is accomplished online for determining optimal paths for each shuttle car.

As the shipping market deteriorates, shipping companies seek to realize economies of scale by promoting the enlargement of container ships. Container terminal operators are increasingly adopting automated equipment and systems in order to quickly provide services and attract traffic. As such, the competition for each terminal to become a hub port is intensifying. Increased automation of advanced container terminals improves productivity and efficiency In the meantime, Korea remains semi-automated. Therefore, the relevant subject survey through SPSS 23.0 program for analysis of recognition difference, We will check the awareness among stakeholders for the smooth introduction.
