국내에 다양한 시스템 엔지니어링 전산지원도구(Computer Aided tools for Systems Engineering)가 도입되고 도구의 기능이 향상됨에 따라 시스템 엔지니어링 전산지원환경을 구축하는 사례가 늘어나고 있다. 전산지원환경을 구축하기 위해서는 기존의 국내외 시스템 엔지니어링 표준 및 지침에서 언급되지 않은 구체적인 업무에 대한 고려가 요구되기 때문에, 많은 노력과 시간이 소요된다. 시스템 엔지니어링 본 연구에서는 국내 연구소 및 기업의 시스템 엔지니어링 전산지원환경을 구축하는 과정에서 습득된 문제점과 경험적 교훈(lessons learned)을 정리하였다.

고속철도는 상당히 복잡한 시스템이기 때문에 적절한 시스템엔지니어링 도구의 사용 없이는 추적관리에 드는 인적비용 및 시간이 만만치 않으며 오류가 생기기 쉽고 매우 비효율적이다. 따라서, 시스템 요건에 정의된 목표 성능을 달성하고 시스템간의 불일치를 최소로 하기 위해 체계적인 시스템 통합 절차를 제공할 수 있는 시스템 엔지니어링 데이터베이스 구축이 필요하다. 이 데이터베이스는 시스템 요건부터 시스템 기능, 컴포넌트, 평가 요건, 평가 결과까지 추적성을 갖도록 구축되어서 연계 관리를 가능하게 한다.

This paper aims to analyze the result of SE Process Implementation on Light Rail Transit(LRT) Project. Currently the Light Rail Transit Project of Korea applies SE to the intermediate phase, that is, E&M phase which is a manufacturing and designing procedure. More seriously, the application effect of SE is not remarkable because it applies to some specific engineering fields like RAMS and it depends on superficial consulting of foreign companies with low SE support capability and investment capital. This study points out that the "Requirement Analysis" and "System Alternative Review" has not been conducted from the initial phase (basic plan and basic design) of the LRT projects. Several projects indicate that the amount of investments for SE activities through the Korea LRT project is relatively very small in comparison with the global capital which is about 10% of total project budget. Furthermore, Korea LRT projects have very few SE professionals and weak SE organization with no government directions and guide book for the efficient implementation of SE for the LRT projects.

The construction of a light rail transit (LRT) system is a large and complex infrastructure project involving hundreds of billions of won in construction costs for a single route, and it is very important to carry out such a project from a life-cycle perspective because of its long-term operation. Systems engineering is a means and methodology to successfully implement customers' needs, and it is useful in large projects such as light rail transit. An application model called Systems Engineering for Light Rail Transit (SELRT) was developed to support systems engineering activities in light rail transit projects. In order to utilize SELRT, it is necessary to ensure that system requirements are met. As such, in this paper, we present a verification procedure and architecture based on a systems engineering-based methodology, thereby identifying the system requirements and deriving the verification requirements to confirm the SELRT model for the proposed method. The results show that the traceability of the system requirements and verification requirements, the verification method for each requirement, and the demonstration results for computerized tools are mutually connected, and that the initial requirements are clearly implemented in the SELRT. The proposed method is valid for verifying the SELRT, which can also be utilized in a LRT project.

INERGEN 의 성능시험으로서 가장 확실한 방법은 직접적인 전량 방출시험이 최선의 방법이나 고비용, 안전문제 및 시험절차의 난이성 등의 이유로 NFPA 2001 이나 선급에서는 직접적인 방출 시험을 가급적 규제하고 있다. 지금까지는 이론적 계산을 통한 서류제출로 대체하거나, 간접 시험방법인 Door Fan Test 를 통하여 소화설비의 적정성을 평가하는 것이 보편적이었다. 하지만 이번 WOODSIDE 선주사의 전례없는 요구로 SHI 에서는 전량 방출시험을 I,G.G. Room 에 대해 수행하게 되었다. 본 자료에서는 조선설게자 관점에서 Full scale test 를 통한 Inergen 성능시험 최적화 방법을 제시하고자 한다.

The analog or partly digital typed interface of main control room in nuclear power plant (NPP) is gradually being replaced to the totally digitalized interface suitable for the digital environment. SKN 3,4 Nuclear Power Plant is currently developed in such a way to employ advanced displays and controls such as computerized procedure system(CPS), large display panel(LDP), and Soft control. According to the developed design process, the main control room (MCR) of the SKN3,4 was aesthetically designed based on a design concept of the health and sustainability and technically evaluated with human factors guidelines, which somehow lack of the confidence on the evaluation for the rapidly changing digital environment. The suitable review guideline for the digitalized interface and the environment was developed such as the guideline for CPS with information displays on VDU. For the guideline development, tremendous guidelines and technical papers related to evaluation issues of digital environment has been collected, analyzed and transformed to electric database forms and then built on database management system, called Design Review Supporting System to retrieve the appropriate issues for the practical usage of evaluators-in-field.

It is well known that efficient management and thorough implementation of stakeholder requirements is vital for a successful development of a large-scale and complex system. Equally important is to make sure that all the requirements be correctly realized in the developed system. For the purpose, verification requirements are derived with traceability from the system requirements. This paper discusses a step by step process for constructing the requirements verification model which includes : 1) the schema modeling both requirements and their traceability; 2) the template documenting the verification requirements; 3) the verification model constructed from the schema; and 4) the test and evaluation plan that can be printed automatically.

최근 비연결지향형(Connectionless)의 IP 상에 연결지향형(Connection-oriented)의 LSP 를 지원하는 MPLS(Multi-Protocol Label Switching) 서비스에 대한 관심이 증가되고 있다. 이는 트래픽 엔지니어링(TE: Traffic Engineering)과 Qos(Quality of Service) 제공 등의 향상된 서비스에 대한 요구사항이 증가하면서, 이에 적합한 차세대 인터넷 서비스의 효율적인 제공 방안으로 IETF 에서 표준화하고 있는 MPLS 기술이 대두되고 있기 때문이다. 이러한 사용자의 요구사항을 만족하기 위하여 한국전자통신 연구원에서는 ACE2000 MPLS 시스템을 개발했으며, 초고속망에 적용되는 MPLS 시스템을 관리하기 위한 관리 시스템을 개발하였다. 본 논문에서는 SNMP(Simple Network Management Protocol) 기반의 MPLS 망 관리 시스템과 트래픽 엔지니어링 관리 기능을 중심으로 관리 대상, 관리 수행 절차 등을 설명한다.

To develop a plant safety training system using virtual reality technology, we constructed a training system for a large scale plant. Compared with safety training for small plants or unit equipment, many system configurations such as virtual plant model, in-process data processing, work instruction, etc. are required and integrated system works have been carried out. The target plant, RDS process, is a high-risk process(high-temperature, high-pressure) that takes into account the training scenarios that can be taken in the event of a leaking fire in the range and refer to the actual shutdown procedure. The proposed safety training integration system can be used in similar situations that can occur in the RDS process and can be a platform for safety training using virtual reality in a large plant.

This study introduces the verification, validation & accreditation (VV&A) process for modeling & simulation (M&S). VV&A is standard process for credibility of M&S. In several countries including USA, for weapon system of Defense Development using M&S, VV&A is necessary procedures to acquire official approving for credibility of M&S. Many countries have regular recommend practice guide (RPG) and instructive for VV&A of M&S. In this study, we focus the VV&A key concepts as Department of Defense RPG of USA and give the outline of the main VV&A concepts because we don't have any available VV&A Instructive. Also, this report documents the first significant VV&A application for a MITS(M-SAM Integrate Test System) including Verification and Validation(V&V) activity and tasks.
