Systematic and efficient Management of Development requirements will lead to success of project such as aircraft system development consisting of complex subsystem. For such reason, Requirements management tools have been used in most of project. In the case of FA-50 development project, requirements management tools have been used for systematic and efficient management of FA-50 Requirements. Especially FA-50 system was designed on the basis of the TA-50 configuration. Therefore, it needs traceability of requirements about functions, which have been already developed and will be newly developed. This paper was described about the implementation method of FA-50 development requirements traceability management.

Software inspection is widely believed to be an effective method for software verification and validation (V&V). However, software inspection is labor-intensive and, since it uses little technology, software inspection is viewed upon as unsuitable for a more technology-oriented development environment. Nevertheless, software inspection is gaining in popularity. KAIST Nuclear I&C and Information Engineering Laboratory (NICIEL) has developed software management and inspection support tools, collectively named "SIS-RT. "SIS-RT is designed to partially automate the software inspection processes. SIS-RT supports the analyses of traceability between a given set of specification documents. To make SIS-RT compatible for documents written in Korean, certain techniques in natural language processing have been studied [9]. Among the techniques considered, case grammar is most suitable for analyses of the Korean language [3]. In this paper, we propose a methodology that uses a case grammar approach to analyze the traceability between documents written in Korean. A discussion regarding some examples of such an analysis will follow.

소프트웨어 개발 시 요구사항들이 개발시스템에 반영되었는지 추적하는 일은 매우 중요하다. 하지만 기존 연구들은 대부분 요구사항추적표를 개발관리방법론에 따른 전체 SDLC에 모두 적용하고 있다. 그리고 추적항목이 많으며 추적방법이 복잡하여 실제 정보시스템 개발에서는 실질적인 관리가 거의 이루어지고 있지 않아 실용성에 한계가 있다. 따라서 본 연구에서는 요구사항추적표를 제안요청 및 제안단계부터 SDLC단계 중에서 효과적으로 관리할 수 있는 적용범위와 요구사항추적에 꼭 필요한 항목만을 구성한 개선된 추적표를 제안하고 이를 적용한 K사의 정보시스템 개발프로젝트의 6개 실제 적용 사례를 통하여 그 효과를 확인 하였다.

This paper will describe the design of database for system engineering of High Speed Railway Systems, focusing on tile ability to capture a full thread of traceability, from tile inception of a system requirement, to the test results that validate that the designed system meets criteria defined by the requirement. The database includes data models for requirement, function, component, work, work process, resource, etc.. These data models are utilized for tile efficient management of data related system design, development work, and validation.

We proposed a methodology to automatically extract the requirements from the documents and check the consistency and traceability among them. The documents include not only text but also PDF or image files. We also suggest a method to visualize the result with maps, numbers, and graphs. By comparing the results with those of manual reviews from experts, we show that it is necessary to use knowledge-based method in future instead of the wordbased method for improving the reliability. The results can be applied effectively for already existing documents.

The HEMU-400X project starts at 2007. It is important first of all that describing correctly system requirement during configuration of system, design, manufacturing, installation and test verification so that the complicated high-speed electric multiple unit is to run safety and reliable and to achieve target performance and function properly. The system requirement assist the system designer to understand the performance and function of system in basic design. For this process, system engineer have to manage the system requirement. This paper proposes the management contents of system requirement such as change management, requirement traceability, etc, for HEMU-400X.

연결불가능성(unlinkability)과 추적불가능성(traceability)은 그룹-서명이 만족해야 하는 기본적인 요구사항이다. 본 논문에서 최근 Lee등과 Zhu등에 의해서 제안된 두 그룹 서명기법들이 갖는 취약점을 분석하였다. Lee등의 기법은 합법적인 서명자가 생성한 서명을 검증할 수 없는 설계상의 치명적인 문제를 갖고 있으며, 검증과정이 안고 있는 문제와 별개로 동일한 서명자가 생성한 서명을 항상 링크할 수 있음을 보인다. 또, Zhu등의 그룹서명기법에서 그룹의 관리자가 추적할 수 없도록 서명을 생성하는 것이 가능함을 보이고, 저자들의 주장과 달리, 그들의 기법이 전방향 안전성을 만족하지 않음을 보인다.

It is necessary to develop the requirement management system that could trace hazards and manage safety requirements for risk control of railway accident as low as reasonably practicable. In this paper, the requirement management system for control of railway accident risk is introduced. The requirement management system is containing the railway system configuration and safety activity related with identified hazards. The system shall be used to derive safety requirements for risk controland support the traceability of hazards on railway's operation & management. In the future, the system will be applied in the areas such as risk assessment and management, performing safety assurance and revising national regulations etc. for continuous safety improvement in the railway.

The weapon system applies the rule that the system engineering procedure must be applied at the acquisition stage. Naval ships, which are one of the important naval weapon systems, take a long period of time to acquire, and the leadership must be commissioned. Therefore, in order to acquire a naval ship, high risk management is necessary, and it is necessary to promote business success through effective application of system engineering which is a scientific management method. However, in the case of naval ships, there are no specific procedures and methods for applying the system engineering. Therefore, research on application method of system engineering which can be easily used by person in charge is necessary. This should have a simple approach to ensure effective business performance by systematically refining and simplifying existing works. QFD (Quality Function Deployment) is a way to improve product satisfaction, impress customers, reduce defective products, reduce design errors, and reduce costs. This systematically develops these mutual relationships by converting the needs of customers into quality characteristics of products and defining them as the design quality of products considering the functions, quality, and process elements of parts. The purpose of this research is to present concrete methodology at the practical level using QFD in a way to ensure traceability of requirements which is an important element of system engineering.

추적 링크는 요구사항과 아키텍처 설계서, 소스 코드, 테스트 케이스 등과 같은 시스템 산출물들 사이의 논리적인 연결을 의미한다. 이러한 추적 링크는 요구사항 변경 영향 분석, 요구사항 충돌 분석, 요구사항 일관성 점검에 매우 유용하다. 그러나, 복잡한 소프트웨어 개발시 많은 다양한 산출물들이 만들어지므로 추적 링크를 생성하거나 운용하는 것은 많은 부담을 초래한다. 본 논문은 가치분석을 근간으로 하고 휘처를 중간 매개체로 활용하는 휘처 기반의 요구사항 추적 기법을 제안한다. 이는 사용자 요구사항과 산출물간의 추적 링크를 생성하기 위한 중간 매개체로 휘처 개념을 적용하였고, 식별된 휘처들의 상세화 정도를 추정하기 위하여 요구사항의 우선순위에 따른 가치 평가를 포함한다. 또한, 본 논문에서 제안한 휘처 기반의 요구사항 추적 기법을 아파트 단지 내 홈 서비스를 통합하는 유비쿼터스 플랫폼에 적용한 사례의 결과를 기술한다.
