소프트웨어 개발공정 상의 요구사항 문서적 분석에 치중되어 있던 요구사항 분석에 관한 논의는 기업 통합을 더욱 효과적으로 하기 위해 소프트웨어적 차원을 넘어 기업 아키텍처 기반의 정보시스템 개발 및 통합의 필요성에 대한 논의로 확대되고 있다. 본 연구에서는 궁극적으로 기업 아키텍처의 효과적인 수립을 지원하는 요구사항 분석, 관리 프레임 웍과 분석 프로세스를 제시한다. 요구사항 분석 프로세스는 기업 아키텍처의 개념을 바탕으로 다양한 사용자와 관점이 구별하고, 이를 다시 요구사항 추출을 위해 업무적 관점과 정보시스템 관점으로 구분한다. 이러한 요구사항 분석을 위한 프로세스는 기업 아키텍처의 수립을 효율적으로 지원할 것이다.

This paper presents the optimum design methodology for composite wing structure which automatically calculates the safety margin using optimization framework integrating failure modes. Particularly, its framework is possible to optimize sizing procedure to prevent failure mode which has the greatest effect on reducing the sizing time of composite structure. The main failure mode was set as the first ply failure, buckling failure mode, and bolted joint stress field, and the margin was calculated to minimize the weight. The design variable is a laminate sequence database and the responses are strain, buckling, bolted joint stress field. The objective function is the mass of the wing structure. The results of buckling analysis were compared using the finite element model to verify the robustness and reliability of Composite Optimizer.

For Optimization technology Was Developed in 1960, the Optimization Technology have grown into a full-featured, robust, highly rated and highly used. And Optimization techniques, having reached a degree of maturity over the past several years, are being used in a wide spectrum of industries, including aerospace, automotive, chemical, electrical, and manufacturing industries. With rapidly advancing computer technology, computers are becoming more powerful, and correspondingly, the size and the complexity of the problems being solved using Optimization techniques are also increasing. But Optimization techniques with analysis solver have many problems. For instance, the difficulties that a particular interface must be coded for each design problem and that the designer should be familiar with the optimization program as well as the analysis program. The purpose of this paper is Optimal Design Framework for Mechanical systems design. This Design Framework has two Optimizers, ADS (local optimizer) and RSM(Response Surface Method), and graphic user interfaces for formulation and optimum design problem and controlling the design process. Current Design Framework tested by two analysis solver, ADAMS and ANSYS. First this paper focused on the core Framework and their conception. In the second of the paper, I cover subjects such as Design Framework Operation. Next, The validity and effectiveness of Design Framework are shown by applying it to many practical design problems and obtaining satisfactory results. Finally, if you are an advanced Operator, you might want to use Response Surface Method, so that cover the result applied by RSM. here.

본 연구는 글로벌하고 분산된 환경하에서 다중 에이전트에 기반한 공급업자선정과 이를 통한 글로벌 제조를 위 한 프레임 웍을 구축하고자 하였다. 에이전트 시스템을 위해서는 KQML에 기반을 둔 메시지 전달 시스템에 근거하여 에이전트 통신 계층, 메시지 계층 및 내용서술계층으로 구분하였다. 또한 분산된 객체간에 클라이언트간의 통신을 위해서는 고정된 인터넷 프로토콜의 주소를 없어도 통신이 가능하도록 OLE automation서버와 ORB (Object Request Broker)를 이용하여 시스템을 구축하였다. 시스템 구현을 위해서는 스포츠용 신발을 주로 수출하는 중소기업의 업무를 대상으로 하여 정해진 생산계획에 대하여 관련 부품을 생산 납품할 수 있는 외부 공급자를 선정하는 업무에 대하여 프로토 타입을 만들어서 시험하였다. 네트웍시설이 열악한 동남아 등지에 협력업체를 많이 보유하고 있는 한국의 섬유분야나 신발산업 같은 분야에 있어서 본 시스템의 활용 가능성이 기대된다.

This paper presents the automated component generation system to support development of web application by the Model 2 framework on distributed environment. Model 2 framework is based on MVC(Model View Controller) model and this model capsulate the functionality of web application and have the benefits like extensibility, maintainability, resuability. In this paper, we propose a framework which is adapted in JSP environment and implement the automated component generation system. This system can efficiently utilized for web application development which require extensibility, maintainability, resuability as well as rapid web application development.
