정보통신시스템 요구사항 분석을 위한 기능 모델링 연구

초록

Urban transit consists of signaling system, railway systems, power facilities systems, information and communication system and the other complicated facilities. There are many new technologies to analysis the requirement of for information and communication system. The more system is complicate, the more system design error occur frequently in development of information and communication system. Now, we need to reduce the error by analysis the behavior of the requirements of it. Thus in this paper, we suggest the way to analysis the behavior of the requirements by using the computer aided design tools.
