        최근 세계 각국은 국가 안보, 국민 삶의 질 향상 등 국가 발전을 위한 중점 분야로 우주개발을 추진하는 신(􅨅) 우주개발 경쟁시대에 돌입하였다. 각국 정부는 국가의 미래 성장 동력으로서 우주활동에 대한 투자를 지속적으로 하고 있고, 또한 많은 민간 산업체는 유용한 우주 제품과 서비스 분야에 대한 상업적인 활동을 증가시키고 있다. 우주발사체는 우주공간으로의 접근을 위한 유일한 운송 수단으로서 우주개발을 위해 필수적인 시스템(체계)이다. 우주발사체는 고성능, 고신뢰성, 극저온·초고온, 초고압, 고청정 등 극한 기술의 적용과 십만 개 이상의 부품으로 구성되는 대표적인 대형복합 체계이다. 이러한 우주발사체 개발을 위한 사업은 개발 기간 동안 예상할 수 없는 많은 기술적 불확실성이 잠재되어 있어 매우 도전적인 프로젝트이다. 따라서 우주발사체 개발 사업에서 계획된 일정과 예산 범위 내에서 기술적 임무 목표를 성공적으로 달성하기 위해서는 발사체 핵심 기술과 함께 성숙된 체계 관리 기술의 적용이 필요하다. 한국항공우주연구원은 국가 우주개발 중장기계획에 따라 한국형 우주발사체를 첫 독자 개발하 기 위한 개발 사업을 진행하고 있다. 본 강연은 발사체 핵심 기술 확보를 위한 연구개발 활동과 더불어 체계관리 기술의 성숙도를 높이기 위해 한국형 우주발사체 개발 사업에 맞는 실제적인 체계관리 체계를 수립하여 적용하고 있는 현황을 소개하고 점진적인 개선 방향을 모색하고자 한다.

        It is important to complete the project within the specified time period and the limited budget in the current rapidly changing business environment. It is difficult to predict the cost of the project in early stage because of the large-scale trend. Budget shortfall due to the failure of cost prediction serves as a higher risk of success. Most previous studies to prevent the risk such as budget shortfall have investigated the direct costs. However, research on the overhead costs are insufficient in terms of both quality and quantity. Direct costs are easily computed for each basis of calculation. But overhead costs that include indirect costs except indirect material cost(IMC) are necessary reasonable and efficient management because they are changed in accordance with the rate of overhead costs. In this paper we introduce an analysis method of overhead costs applied for a Space Launch Vehicle R&D Project.

        A space launch vehicle system represents a typical example of large-scale multi-disciplinary systems, consisting of subsystems such as mechanical structure, electronics, control, telecommunication, propulsion, material engineering etc. Mission assurance for launch success is needed over the lifecycle of a space vehicle development program and through launch. This study suggests a comprehensive approach to analyzing failure spaces of space system failures, especially launch failures, from viewpoints of latent conditions and active failures in Reason's Model. First it reviews methods to identify process failure spaces using systems engineering process as latent conditions and explains their analysis results. Second it reviews literatures to identify physical failure spaces, deficiency areas of launch vehicles itself, as active failures and explains their analysis results.

        This study developed the planning process for technical management of engineering project applying systems engineering process in order to correctly design technical management activities early during the system development projects. The developed process describes a systemic design process of a product to be developed as well as the development process and the personnel team of project organization. As an outcome of the process implemented by a Model-Based Systems Engineering(MBSE) software, a systems engineering management plan(SEMP) and a risk management plan can easily be produced.

        Risk Management is an organized method for identifying and measuring risk and for selecting, developing, and implementing options for the handling of risk. The Risk management covers all programatic and technical factors which affect the system development performance, cost, and schedule. While technical issues are primary concern for systems engineering during a program, the three elements(performance, cost, and schedule) must be balanced for a successful risk management process and program. This paper describes the risk management process and intial results for the KSLV-I(Korea Space Launch Vehicle-I) program using computer-aided systems engineering tool, Cradle. The risk management process of KSLV-I program is similar to the general risk management process, but it has its own specific features to manage large-scale complex characteristics of KSLV-I program.
