항만컨테이너터미널에서는 컨테이너 생산성뿐만 아니라 하역작업 안전성도 중요하게 고려되고 있다. 생산성 증대를 위해서 도입되는 대형 하역장비의 운영 효율성과 더불어 하역장비를 운영하는 장비기사들의 작업안전성 향상도 중요함에 따라 하역장비기사를 대상으로 하역장비 교육훈련 실시가 필요하게 되었다. 그러나 실제 하역장비운영을 통한 교육훈련은 장비운영비용과 위험성이 수반되기 때문에 경제적으로 장비 운영 시 발생되는 문제점을 최소화시키는 방법 가운데 하나가 항만크레인시뮬레이터를 이용한 하역장비 교육훈련이 제기되고 있다. 이에 본 연구는 교육기관에서 보유하고 있는 실제 항만의 운영환경을 고려하여 개발된 최첨단 장비인 항만크레인시뮬레이터를 이용한 부산항 신항만을 중심으로 하역장비기사 교육현황과 그 성과를 통한 항만크레인시뮬레이터 장비 효율성을 제시하고자 한다.

부산항 및 부산신항 개발의 특징은 매립으로 인하여 가항수역은 협소화되는 반면에 선박은 대형화되면서 흘수가 증가함으로 인하여 점점 더 깊은 수심을 필요로 하게 되었다. 따라서 초대형선들은 출입항선 상호간의 간섭이 증가하고, 심흘수화로 인한 조종성능의 저하와 비상시 대응책의 한계를 드러내는 등의 문제점을 안고 있다. 또한 전반적인 선박 통항량의 증가는 거대형 컨테이너선이 부두전면에서 회두하거나 감속, 접근하는데 소요되는 시간에 따라서 항만의 효율성뿐만 아니라 주변수역의 안전에도 크게 영향을 미치고 있다. 따라서 본 연구에서는 항만의 안전과 효율성을 제고하기 위하여 초대형 선박의 조종특성과 주변 여건을 다각도로 고려한 최적의 표준 조선방법 및 응급조선을 2D베이스로 개발된 선박조종시뮬레이터를 이용하여 모색해 보고자 한다.

In order to effectively operate and manage the port terminal, it is necessary to use port terminal simulator for the analysis of port terminal. However, there are many difficulties in applying an existing port terminal simulator to various terminals, because each of the port terminals has different structures, facilities, equipment, and job processes. Therefore, in this paper, we propose a design method of port terminal simulator for the improvement of reusability by using model-based techniques. We also showed the implementation of the prototype of the port terminal simulator of applying the research content.

Due to the fast growing rate of the global container trade, every major port is under the pressure of meeting the projected capacity demand. As a result, alternative solutions have been sought for improving capacity and meeting the growing demand for container storage area and terminal capacity. Moreover, material handling process re-engineering is now a critical issue for logistics and supply chain managers of airline, shipping lines, terminal and warehousing enterprises around the world. Therefore, the purpose of this paper is to develop the 3D simulator for executing performance valuation of port transportation systems. The developed 3D simulator system is to measure the effectiveness of the proposed total system and compare it with existing practices. The performance analysis variables are also defined for these comparisons.

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).

According to the increase of container flows and the appearance of large-sized container vessels, the container handling equipment in ports is evolving continuously. This research introduces the simulation model for evaluating in detail the mechanical productivity of container cranes. The model considers a single trolley and dual trolleys as the mechanism of a container crane and a single lift, a twin lift, and a tandem lift as the spreader type of it. Additionally, the detail specifications such as the dimension and the speed of a container crane are inputted and the kinematic characteristics of it are simulated. The model also considers the size of a vessel, the storage position of containers in the vessel, and the weight of containers as external physical constraints. Experimental conditions can be configured conveniently because various parameters in the model are separated. Moreover, the model can accommodate flexibly new equipment types and the changes of the existing equipment because it is designed and developed in object-oriented concept.

The container terminal is the unified transportation system which connects between a land transportation and a sea transportation. This system has many subsystems such as ship operation, yard transfer operation, yard storage system, gate operation, and information manage system. This paper presents a method of modeling a simulator with which user can evaluate the efficiency of the equipment and allocation policies in the container terminal. The final purpose is to estimate the efficiency of each equipments and the distribution policies. In a design step in the simulator development. We suggest the Object Oriented method with which the developer can easily design, because the object oriented method has the advantages of reusability and modularity.

In general mechanical servo systems, friction deteriorates the performance of controllers by its nonlinear characteristics. Especially, friction phenomenon causes steady-state tracking errors and limit cycles in position and velocity control systems, even though gains of controllers are tuned well in linear system model. Even if sensor is used higher accuracy level, it is difficult to improve tracking performance of the position to the same level with a general control method such as PID type. Therefore, many friction models were proposed and compensation methods have been researched actively. In this paper, we consider that the variation of mover's mass is various by loading and unloading. The normal force variation occurs by it an other parameters. Therefore, the proposed control system is composed of main position controller and a friction compensator. A parameter estimator for a nonlinear friction model is designed by adaptive control law and adaptive backstepping control method.
