As the automation system in manufacturing field works more efficientely, the automation scheme is applied to many areas. In order to reduce the entire manufacturing, cost the design process must be automated. However, design process is so complicated, it is very difficult to construct the design automation system. The axiomatic approach to design provides a general theoretical framework for all design fields, including mechanical design. The key concepts of axiomatic design are : the existence of domains, the characteristic vectors within the domains that can be decomposed into hierarchies through zigzagging between the domains, and the design axioms. Using this approach, the glass bulb design process was analyzed and the design automation software was developed. Through menu display, a user can select or furnish the design input and generate the drawing with ease.

In order to completely automatize the moving load analysis for the three-dimensional frame model of the girder bridge, the efficient software technique is presented, which makes use of the signal among processes. If this software technique is used in automation, the separate algorithm is not needed for the transverse loading analysis, and the complete automatic moving load analysis algorithm can be easily developed. The program, which has the complete automatic moving load analysis function, has been developed with using this software technique, and has been verified by comparing the results with the one in the famous design book.

본 연구는 도서관자동화시스템에 대한 현황 분석을 기반으로 향후 개선 방향을 모색하는 것을 목적으로 한다. 연구에서는 KESLI와 KCUE 컨소시엄에 참여하는 기관의 담당 사서를 대상으로 설문을 진행함으로써 도서관자동화시스템의 현황과 만족도, 오픈소스 기반 도서관자동화시스템의 현황과 인식을 조사하였다. 연구 결과, 현재 도서관에서 사용하는 자동화시스템은 대부분 2000년대 혹은 2010년대에 외주도입 방식으로 개발되었으며, 도서관자동화시스템 전반에 대해서 50% 이상의 응답자가 만족 의견을 보였다. 전반적인 만족도는 개별 기능 만족도와 고객지원 서비스 만족도, 시스템의 구축 및 운영관리 만족도의 영향을 받는 것으로 확인되었다. 현재 도서관자동화시스템은 대부분 오픈소스 혹은 클라우드를 활용하지 않고 있었으나 향후 활용 의사가 높게 나타났으며, 특히 3년 이내에 도입하겠다는 답변도 40% 이상을 차지했다. 본 연구는 향후 오픈소스기반 도서관자동화시스템 구축을 위한 중요한 기초 자료가 될 것으로 기대된다

Automation of the key flight dynamics operations for the geostationary orbit satellite mission is analyzed and designed. The automation includes satellite orbit determination, orbit prediction, event prediction, and fuel accounting. An object-oriented analysis and design methodology is used for design of the automation system. Automation scenarios are investigated first and then the scenarios are allocated to use cases. Sequences of the use cases are diagramed. Then software components and graphical user interfaces are designed for automation. The automation will be applied to the Communication, Ocean, and Meteorology Satellite (COMS) flight dynamics system for daily routine operations.

Computer Integrated Manufacturing(CIM) is a growing technology as a solution for the total automation of a manufacturing system. However, the implementation in the shop floor is extremely difficult due to many reasons. Flexible Manufacturing System (FMS) is usually considered as a solution for the shop floor automation. One of the difficulties in FMS is the communications problem. Since various machinaries with different communications protocols are included, applying a unified scheme is almost impossible. Therefore, a systematic approach is a key point to solve the communication problem. A cell is defined as an automation unit where closely related for a job reside together. A cell is a messenger between upper level computers and lower level machine equipment. In this research, the functions of the cell are defined to have more capabilities than conventional cell since a cell can be often a total manufacturing system in a small to medium sized factory. The cell conducts communications with different machines through the communications schemes established here. A set of software system has been developed according to the defined communications. The software has been tested for a simulation and real experiments for proof.

Burr is an unavoidable and undesirable by-product of most metal cutting or shearing operations. This burr must be removed to improve the fit of machined parts and safety of workers, to improve the effectiveness of finishing operations. Despite the full or partial automation of FMC or FMS, deburring operations to obtain workpiece with fine surface quality are difficult to be automated since the occurrence and condition of burr are not constant. This study focused on developing a software for deburring automation, which includes automatic recognition of parts, generation of deburring tool path and NC code, by analyzing the IGES format file which contains information of part geometry. The successful performance of developed software was demonstrated by computer simulation and deburring experiment using miniature end brush. And, this research can provide a basis for further advanced studies for automated deburring applications.

'소방시설 내진설계 의무화'에 발맞추어 내진설계의 신뢰성과 효율성 향상을 위해서는 설계 자동화 소프트웨어 개발이 필수불가결하다. 본 연구에서 개발한 내진 설계 자동화 S/W는 소방청의 「소방시설의 내진설계 기준(이하 "국내 기준")」에 따른 흔들림 방지 버팀대(이하 "버팀대")의 자동 배치, 계산서 출력 및 그리고 물량 자동 산출 등의 기능을 제공한다. 또한, 자동화 S/W는 설계자의 수동설계와 비교하였을 때 약 3배 정도의 업무 속도를 단축시켜줄 뿐만 아니라 버팀대 등의 설계물량과 관련한 휴먼에러를 줄임으로써 설계안의 신뢰성을 높여준다. 뿐만 아니라 그동안 보수적으로 접근했던 소방시설의 내진설계방식에 있어 적어도 버팀대 사용에 대해서 컴퓨터 알고리즘을 이용한 최적의 내진설계를 수행할 수 있었다.

This paper proposes an expert system, which is able to determine the problem-solving strategy for diversity events occurred on the distribution system. The events include events related to the fault, scheduled outage and optimal operating task such as feeder line fault, line scheduled outage, line overload, system load balancing, system loss minimization, main transformer fault, main transformer scheduled outage, main transformer overload, main transformer protection control. The expert system enhances the reliability of software designed by the integrated concept for the diversity events. The expert system is implemented in C language. And the effectiveness and accuracy for the expert system is verified by simulating the event cases for typical distribution model.

BACnet is an international standard communication protocol especially designed for building automation and control systems. In this paper, a reference model of network management system for BACnet is proposed and its implementation method is introduced. In order to evaluate the feasibility and validity of proposed network management system, it is applied to a real experimental model of BACnet network system. Proposed network management system complies with standard BACnet protocol and its functions are implemented in software without hardware dependencies so that it can be applied not only to newly installed BACnet system but also to already installed BACnet system by software upgrade. The network management system and its implementation method introduced in this paper will help BACnet-based automation system to be managed efficiently and they can be practically applied in real BACnet-based automation systems.

A test simulator is needed to develop a fuel quantity measurement system that takes into account the roll and pitch motion of the aircraft. In this paper, we develop a test simulator that consists of attitude simulation equipment, fueling equipment, and data storage equipment. The attitude simulation equipment simulates the aircraft attitude. It is manufactured to operate pitch angle and roll angle movement. The fueling equipment supplies fuel to the supplementary fuel tank. The data storage equipment collects and stores the measured data. We also develop an automation software that operates the test simulator and collects data automatically. The test simulator has been automated to prevent testers from being exposed to toxic fuel. Through automation software, the collection period is reduced by one quarter compared to manual collection. The developed fuel quantity measurement system is verified through the test simulator.
