  • 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.

  • Configuration management plays a key role in systems engineering process for any project from earlier stage of development. It consists of five major activities, ie., configuration management planing, configuration identification, configuration control, configuration status accounting and configuration verification and audit, and is essential to control system design, development and operation throughout entire life cycle of the system development. And it is directly associated with other part of systems engineering management process, ie., technical data management which provides traceability of important decisions and changes during development. In this paper, we describe how to apply CASE(Computer-aided Systems Engineering) tool-Cradle for the configuration management to achieve effectiveness of Technical Management process.

  • US DoD operated JCIDS(Joint Capability Integration and Development System) for top down requirement generation. Although the JCIDS can be a good practice for the countries which are trying to shift from bottom up to top down requirement generation, it contains many processes related with review and approval. In this study we structured a joint capability integration and development process from the JCIDS eliminating the organization dependent review or approval process so that it can be applied to any organization with some modification. Furthermore we implemented the process in the computer aided systems engineering tool, Cradle, for convenient use of the process. The result of this study can provide a basic process for top down capability development, and an efficient why of doing each element of the process using CASE tool.

  • 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.

  • The Cradle(R) is specialized systems engineering tool that developed by 3SL(Structure Software System Limited) that has headquarters in U.K. and U.S.A.. It is recognized as the fastest growing Computer-Aided Systems Engineering Tool(CASE Tool). We built up requirements management database by using Cradle(R) on urban maglev program in Korea. So Cradle(R) provide a network function, is available accesses of clients in external organization that is associated on urban maglev program by the internet. However the network function of Cradle(R) require an opening of some a specific network ports and may causes a decreasing network speed. In this paper, we propose the method to establish an user environment of a requirements management database that overcome constraints on network condition.

  • This paper presents a design procedure for the supervisory controller(SC) of the high-speed train car. The proposed SC manages control logic and scenario of the overall train system, and monitors input/output signals among the sub-controllers in the system, The roles and functions of each sub-control system are defined, and the interfaces among the control systems are developed. Train control system is modeled with automata, and the model is implemented into a program using a computer-aided software engineering(CASE) tool, Object GEODE, The designed SC is verified and evaluated by using simulation. The SC is shown to successfully perform the designed functions without any errors.

  • This study investigated the needs and effectiveness of the application of Computer-Aided Systems Engineering Tool in order to enhance the chance of success of the large and complex system development projects like City Train System. Furthermore, it was shown that the merits of Systems Engineering and Project Management must be complementary to each other in their interaction in a project. Especially, for the project plans must be executed based on the fully understood system being developed, the technical and management data of the system development need be integrated and be able to support exact and rapid decision making of project planning. As an alternative solution approach, a model for development knowledge capture integrating both technical and management data of system development was proposed using Computer Aided Systems Engineering tool-Cradle.

  • Computer Aided Software Engineering(CASE) tools are suggested as an automated method for the efficient development of softwares. This study are intended to measure the use level of CASE tools and to provide the meaningful information on the whole software development environment supported by CASE tools. Therefore, the results of a survey on CASE environment in Korea are empirically reported and analyzed. The use of CASE tools is measured; purposes purchasing CASE tools and achievement levels are investigated. Implications from the comparative analysis of the utilization of software engineering methodologies between the CASE user group and the non-user group are described. A proposition is suggested to check the request frequency for program change. Further studies on the reverse engineering, program reuse and the use of CASE tools under distributed processing systems such as client-server environments are suggested.

  • The Systems Engineering, as a methodology for engineering and management of today's ever-growing complex system, is a comprehensive and iterative problem-solving process. The process centers on the analysis and management of the stakeholders' needs throughout the entire life-cycle of a system and searches for an optimized system architecture. There are many essential needs and requirements to be met when a system development task is carried out. Systems Engineering Management Plan(SEMP), as a specification for system development process, must be established to satisfy constraints and requirements of stakeholders successfully and to prevent cost overrun and schedule delay. SEMP defines technical management functions and comprehensive plans for managing and controlling the entire system development process, specialty engineering processes, etc. Especially. in the case of a large-scale complex system development program where various disciplinary engineering such as mechanical; electrical; electronics; control; telecommunication; material; civil engineering etc. must be synthesized, it Is essential to develop SEMP to ensure systematic and continuous process improvements for quality and to prevent cost/schedule overruns. This study will enable the process knowledge management on the subject of SEMP as a core systems engineering management effort, that is, definitely defining and continuously managing specification of development process about requirements, functions, and process realization of it using a computer-aided systems engineering software. The paper suggests a systematic SEMP development process and demonstrates a data model and schema for computer-aided systems engineering software, RDD-100, for use in the development and management of SEMP. These are being applied to the systems engineering technology development task for the next-generation high-speed railway systems in progress.
