A STUDY ON THE REQUIREMENT TRACEABILITY OF URBAN TRANSIT SYSTEM USING FUNCTIONAL ANALYSIS

초록

The urban transit system is operated by driverless and automatic. In driverless and automatic system, the system function is accomplished exactly to obtain the safety and reliability of system and the system is designed to minimize risk. In order to design the system, the functional analysis is performed. Recently functional analysis is performed by design tool which is used and verified by aerospace, military, etc. Generally, the design tool is used to perform functional analysis in urban transit system development project. The design tool assist the system engineer to analysis the function of system in basic design. Therefore, In this paper, it is performed the functional analysis to satisfy the system requirement of urban transit system and to confirm the operation of system using design tool."
