This paper aims to suggest the strategies for Korea port, especially Busan to develope into a viable transhipment center and/or Hub port as the articulation points between mainline and feeder nets. To tackle this goal, the authors clarify the requirements for Korea port which will be critical in determining its position as Hub through the careful analysis on competitiveness, environmental impact, port policy and capacity, transhipment traffic and inherent ablity to generate traffic. The results are summerized as follows. (1) Coping with increasing container volumes, new investment is sustainedly necessary to increase the capacity and inherent ability of container port and create economies of scale. Moreover, increasing port capacity will increase the potential for the Korea port's inclusion into mainline rather than feeder networks. (2) Considering an increasing awareness of need for customer-oriented option s and service quality rather than simply a reliance on infrastructure-led efficiency, privatization of one sort or another and corporation of port have been key strategies in achieving greater efficiency in Korea containerport.

For the purpose of building the simulation model on cargo handling capacity in container terminal we composed a model of container logistics system which has a 4 subsystem; cargo handling transportation storage and gate complex system. Several data are used in simulation which were gained through a field study and a basic statistic analysis of raw data on BCTOC from January to Jane in 1998. The results of this study are as follows; First average available ratios of each subsystems were 50% for G/C, 57.5% for Y/T, 56% for storage system and 50% for gate complex. And there were no subsystems occurring specific bottleneck. Second comparing the results of simulation to the results of basic statistics analysis we can verifying the suitability of this simulation model. Third comparing the results of this study to the results of existed similar study in 1996, we were able to confirm the changes of container logistics system in BCTOC.

최근에는 Non-PC 디바이스들을 위한 Embedded OS들이 PCS, PDA, 핸드헬드(Handheld) 컴퓨터, 터미널, 산업용 제어기 및 다른 소형 컴퓨터에서부터 인터넷 TV, 디지털 셋탑 박스, 웹폰, 인터넷 디바이스, 및 Mobile Computing 분야에 이르기까지 다양한 분야에서 그 요구가 급증하고 있다. 현재 이러한 응용들은 사용자의 응답시간이 빠른 표준 API(Application Programming Interface)의 사용을 필요로 한다. Window System의 Application을 개발하기 위해서는 보통 Win32 API를 사용한다. 그런, Win32 API에서 제공하는 자료형과 관련 함수들이 크기가 크고 속도가 느려서 소형의 적은 메모리와 빠른 속도를 필요로 하는 PCS 단말기에는 적합하지가 않다. 따라서 기존의 API의 기능을 충실히 수행하면서 PCS에 최적화된 API에 대한 연구가 필요하다. 본 논문에서는 PCS 정보단말기용 소형 운영체제에 적합한 API를 GWES(Graphics, Windowing, and Events Subsystem) 모델을 기반으로 설계하였으며 사용자 응답시간 지연을 해결하기 위해서는 Event 처리를 최소화하는 다중 메시지 처리 방식을 개발하였다.

Construction of automated terminal it urgently demanded to gain the foundation of hub-port in north east Asia. Therefore we suggest an adequate operating system layout 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 selected, and designed for yard operating system layout on the basis of the selected model. Particularly, the productivity of automated port is up to the kind of automated equipments. However, because expense and present work process must be considered actually. In order to prevent confusion of the work, the method to optimize the present work and substitute prevent equipments and automated equipments was designed. It is a premise that ail the yard equipments described in this paper must be automatic except quay crane.

This paper focuses on the integration aspect of operators to determine an improvement strategy for the operating system to enhance competitiveness of Busan Port. This Study proposes the following alternatives: valuation standards for the integration of operators, the road map for the integration period, the scope and role setting of integrated operators' participation of Busan Port Authority(BPA), and the separation and linkage North Port and the New Port operators. First, the valuation standards for operator integration should be based on international standards. Additionally quantitative factors such as financial situation, business performance and participating companies' profitability, and the qualitative factors such as management ability, technology, and labor relations should be considered. Second, the timing of North Port's operator integration should be prioritized in the short term in conjunction with the commencement of its phase 2-4, 2-5, and 2-6. The integration of New Port operators should provide a road map for a relatively long-term perspective. Third, the participation of BPA' integrated operators should be considered in terms of publicity as a policy coordinator between terminals and by pursuing the profitability of entering into overseas business by fostering Korean global terminal operators. The scope and role of participation ensures that the experience and technology of the terminal operation business is maximized. Fourth, because physically intergrating the North Port' operator into a single corporate form is difficult, initially establishing a special purpose company to maximize the effect of the integrated operation is necessary. Then, the operators decided to convert to a holding company given the termination of the lease term contract with the State or BPA, and ultimately proposed a merger into a single corporation.

In modern automated container terminals, automated guided vehicle (AGV) systems are considered a viable option for the horizontal tansportation of containers between the stacking yard and the quayside cranes. AGVs in a container terminal move rather freely and do not follow fixed guide paths. For an efficient operation of such AGVs, however, a sophisticated traffic management system is required. Although the flexible routing scheme allows us to find the shortest possible routes for each of the AGVs, it may incur many coincidental encounters and path intersections of the AGVs, leading to collisions or deadlocks. However, the computational cost of perfect prediction and avoidance of deadlocks is prohibitively expensive for a real time application. In this paper, we propose a traffic control method that predicts and avoids some simple, but at the same time the most frequently occurring, cases of deadlocks between two AGVs. More complicated deadlock situations are not predicted ahead of time but detected and resolved after they occur. Our method is computationally cheap and readily applicable to real time applications. The efficiency and effectiveness of our proposed methods have been validated by simulation.

The global container terminal market is predicted to see continued future volume growth. According to Drewry, global container shipments rose by 6.3% year-on-year to 750 billion twenty-foot equivalent units (TEUs) in 2017 and are forecast to experience continued growth to 9.3 billion TEUs in 2022. According to IHS Markit, the global terminal operator (GTO) market is forecast to grow more than 10% annually, up from $2.4 billion in 2017, to exceed $3 billion by 2022. However, Hyundai Merchant Marine is the only real GTO in Korea. In particular, the shipping and port markets are facing drastic changes, both at home and abroad, including a slowdown in the growth of domestic export and import shipments, environmental changes in the container market caused by the trade frictions between the US and China, and increased changes in container shipments caused by the trade frictions between Korea and Japan. In this study, we propose ways for domestic companies to participate in the continuously growing GTO market. After analyzing the current status of the global GTO market, the government expressed a desire to explore ways to establish GTOs through the Port Authority and the Korea Ocean Business Corporation. Therefore, four types of establishment plans were proposed, along with a legal framework for the establishment of GTOs.

A methodology to the operation standards of the service performance of airport terminal fadlities using Perception-Response Model is discussed in this paper. The proposed approach has defined as the graphical presentation of the collective attitudes of a category of passengers towards the range of operational service at a facility of airport terminal. It adopts new concepts to establish service standards through special survey, that can achieve better interpretation of capadty and level of service at each facility. It is expressed in terms of perception of the passenger population of different amounts of the service measure and their response to the respective service conditions classified into distinct levels of satisfaction with service. The methodology can provide a practical service standards of airport terminals and may prove to be a practical and convenient technique to airport planners, designers, consultants, operators, and to airport managers.
