This paper presents the Case of Systems Engineering Application for the Railway Total-Safety Project. Key points to consider for project are: 1) Establish the SE Based-Project organization system, 2) Define the SE Activities, 3) Manage technically the SE Based-Project, etc. They were of much help that the Railway Total-Safety Project which were efficiently implemented and managed. As I take it, the Systems Engineering is very reasonable approach for the systematical and technical conduct of a project.

When a system or service is realized, it needs to be verified by requirements. The process of verification is to check whether customers/stakeholders requirements have been property transformed into a system or service. A set of verification processes is described in the international or industrial standards. However, it is not appropriate to directly apply those verification processes in the national research and development projects. In particular, we noticed the problem in the development of safety systems, standards and process in the railway systems domain. As such, this paper is concerned with a detailed development of the verification process in that domain. Specifically, an effective and efficient verification process is presented regarding the safety systems and process, safety standards, and safety documents. Also, the verification process was modeled by a computer-aided systems engineering tool, Cradle(R). As a result, the outcomes of the verification process on be managed efficiently.

PSS 4000과 같이 표준화된, 또한 사용이 쉬운 자동화 시스템은 사용자들의 초기 투자 비용은 물론 운영 비용도 감소시킬 수 있습니다. PSS 4000-R은 철도 분야 관련 승인이 된 제품이기 때문에 인증 작업량도 상당 부분 줄일 수 있습니다. PSS 4000-R은 같은 제품을 다양한 아키텍처로 구성하여 원하는 안전 무결성 등급(SIL 2, 3, 및 4)을 만족할 수 있습니다. 이러한 어플리케이션은 철도 건설 장비는 물론 레벨 크로싱 신호 감시와 같은 신호 제어 부분에도 사용될 수 있습니다. 각 프로젝트에 적용될 다양한 조건들을 손쉽게 적용 가능함 물론 복잡한 인증 업무도 파격적으로 줄여 줄 수 있는 PSS 4000-R 솔루션은 사용자에게 엄청난 비용절감 효과를 안겨 줄 것입니다.

This paper presents the methods to acquire the Safety Certificate from Independent Safety Assessment based on the IEC standard62279 which is commonly applied to railway system for Automatic Train Control(ATC) system in accordance with Urban Maglev project. This also shows approach methods and relative activities for project life- cycle to accomplish and ensure the system requirements of ATC system, RAMS and S/W quality activities. Furthermore, the key tasks conducted with ISA are noted in detail. These kind of activities for software quality of ATC system to obtain S afety Certificate could be a CASE model to improve the quality of domestic railway system and products, and also contribute to the growth of railway business and toward the achievement of overseas' railway signaling markets.

In this paper, there is the case study which assesses the systems engineering capability maturity of the safety organization that performs the Railway Safety project using systems engineering method. To In ore effective and efficient a research and development to railway safety domain, a new research and development method can be progressively needed such as systems engineering. To assess quantitatively research of systems engineering efforts in the railway safety project, SECM(EIA/IS 731) Standard is utilized in the paper. It is by questionnaire that the capability maturity assessment is executed wit h the safety organization and staffs who performs the systems engineering activities; requirement analysis and management, interface control management. product verification and validation, and so on. As a result, the systems engineering capability level of the safety organization rises from 0 level at the initial project to 2 level after two years and all staffs give an affirmative answer about the importance and effectiveness of the systems engineering approach.

The Systems Engineering Management Plan (SEMP) is the primary, top level technical management document for the integration of all engineering activities at the project plan phase. This document defined the activities to plan, control, and perform overall engineering integration. To develop the SEMP for Railway Safety System, several standards are reviewed and analyzed. And then a common requirement for SEMP preparation is derived from the results of analysis. Also, the SEMP example available practically applies to Railway Safety System. In particular, The SEMP focused on controling technical program management has been organized so far, but in this study the detailed contents of SEMP put stress on project management is derived. And it is related to each other between project management and technical engineering management. At the end, to continuously manage the items and contents of the SEMP, a database management and an automatic document generation system is presented using Computer-Aided Systems Engineering (CASE) tool.

This paper presents the methods to acquire the Safety Certificate from Independent Safety Assessment based on the IEC or EN standard which is commonly applied to railway system for Automatic Train Protection (ATP) system in accordance with ERTMS/ETCS Level 1 system. This also shows approach methods and relative activities for project lifecycle to accomplish and ensure the system requirements of ATP system, RAMS and system quality activities. These kind of activities for quality assurance of ATP system to obtain Safety Certificate could improve the quality of domestic railway system based on On-Board system of ERTMS/ETCS Level 1 and also contribute to the growth of railway business.

During the complex systems development, a great deal of data are generated from both the systems engineering process and project management process, and also some data are required to be prepared for the system engineering management plan (SEMP). For the successful completion of the project, it is necessary to effectively manage all the data in order to maintain data consistency and traceability. To fulfill the necessity, this paper introduces the concept of an integrated data architecture and discusses its realization with $Cradle^{(R)}$(a computer aided systems engineering tool). Also, it was described how to automate the production of the SEMP in that working environment. The result of the approach, managing complex data efficiently in the systems engineering view, has been successfully applied in the Railway Safety Development Program.
