A CHS(Container Handling System) is a system to load and to unload ISO 2000 or ISO 4000 standard containers which is widely used for various industrial transport purpose. A new light type of CHS is introduced in this paper, in order to reduce weight of cargos and to give the convenience in cargo loading and unloading without additional lifting equipments. The structural models of this system are created to assemble the smooth integration of system and to interface the each composing units with the specification of truck chassis to be mounted. These models are applied to find the suitable design parameters under the condition of force restrictions of each units. Finally, the stability of this system are investigated by analyzing the dynamic simulation using Visual NASTRAN 4D, and it could be recommend the good design parameters for the manufacturing purpose.

In this study, it is performed that the assessment of feasibility of developed material processing facilities using tele-operation manipulator system for the pyroprocessing. To evaluate the performance of developed facilities using tele-operation system, several performance indices are considered as remote visibility, remote reachability and remote manipulability. These are applied to RHEM (Remote Handling Evaluation Mock-up) and digital mock-up system respectively. Through this approaches, several requirements for the system improvement are deduced and preliminary inspection for real system application is fully performed. Additionally, assembly and disassembly tasks for the repair of remote handling system are also examined remotely in RHEM and evaluated those performances.

업무프로세스 관리시스템(BPMS：business process management system)을 이용하면 새로운 프로세스를 정의하거나 기존의 프로세스를 갱신하는 일이 매우 용이하다. 대체로 표준화되고 일상적인 업무를 대상으로 프로세스를 관리하는 것은 이러한 소프트웨어를 사용하여 효율성을 높일 수 있겠으나, 비일상적인 예외상황에 대한 처리를 위해서는 별도의 전문가 참여나 특수한 의사결정 과정을 거쳐야 하는 경우가 많다. 본 논문은 다수의 예외처리용 업무 프로세스가 저장소에 축적된 상황을 전제로 예외처리 프로세스 선정의 자동화 방안을 제시한다. 예외처리에 가장 적합한 프로세스를 검색하는 것은 예외상황에 관한 충분한 이해가 필요하기 때문에 상황의 인지(context awareness)는 매우 중요한 과제이다. 예외상황의 이해를 원활히 하고, 예외처리 프로세스의 효율적인 선정을 위해 본 연구에서는 '상황변수'와 '의사결정변수' 자료구조를 도입하였다. 전자상거래의 배송과정의 예외사례를 사용하여 제시한 변수구조가 어떻게 검색트리 생성에 활용되는지를 예시하였다. C5.0 알고리즘은 최적검색트리를 생성해주며, 그것은 또한 문제의 상황에 최적인 예외처리 프로세스의 선정을 위한 검색경로를 설정한 것임을 보여준다.

In this study, the graphical design system is developed and the digital mock-up is implemented for designing the spent fuel handling and disassembling processes. This system is used throughout the design stages from the conceptual design to the motion analysis. By using this system, all the processes involved in the spent fuel handling and disassembling precesses are analyzed and optimized. Also, this system is used in developing the on-line graphic simulator to enhance the reliability and safety of the spent fuel handling process by providing the remote monitoring function of the process. The graphical design system and the digital mock-up system can be effectively used for designing the process equipment, as well as the optimization of the main processes and maintenance processes of the spent fuel management.

Recently, many enterprises are installing AMSs(Automated Manufacturing Systems) for their competitive advantages. As the level of automation increases, proper design and validation of control logic is a imperative task for the successful operation of AMSs. However, current discrete event simulation methods mainly focus on the performance evaluation. As a result, they lack the modeling capabilities for the detail logic of automated manufacturing system controller. Proposed in this paper is a method of validation of the controller logic for automated material handling system using an object-oriented design and simulation. Using this method, FA engineers can validate the controller logic easily in earlier stage of system design, so they can reduce the time for correcting the logic errors and enhance the productivity of control program development Generated simulation model can also be used as a communication tool among FA engineers who have different experiences and disciplines.

It is conducted to analyze vibration loads on KSR-III(KSR: Korea Sounding Rocket) and its major segments during their ground transportation and various handling process. These loads may be different from the real flight environment. Inadequate assessment of these loads can cause not only local damages on the rocket system but also the critical problem like flight mission failure. Therefore, transportation and handling loads must be considered during design and attenuated to ensure that the rocket structural damage does not occur. This work is concerned with the generation of criteria and prediction of transportation and handling loads for KSR-III. The results show that the shipping container is well designed to satisfy the design requirements. The maximum vibration level recorded during whole transportation and handling for KSR-III is less than 2g, the criteria of KSR-III movement condition.

선박 조종자는 방파제를 통항할 경우 조선 부담감을 느낀다. 아직까지 선박 운항자의 조선 부담감을 고려한 방파제 배치에 관한 기준은 없다. 이 연구는 해상교통류 시뮬레이션을 이용하여 조선 부담감이 발생하는 상황을 재현하여 선박 운항자의 조선 부담감을 정량적으로 표현한 모델인 환경스트레스모델을 재현된 상황에 적용, 평가하였다. 주요한 결과는 다음과 같다. (1) 방파제 배치 변화에 의한 조선 부담감의 차이는 그다지 크지 않다. (2) 동일한 방파제 폭일 경우에는 선박의 항행속력의 차이로 인하여 선박 운항자의 조선 부담감은 상이하다. (3) 방파제폭의 확장함으로써 선박 운항자의 조선 부담감이 평균적으로 감소한다.
