Abstract

The system safety must be ensured before customization. There was no specific requirement representing system safety in Korea until now. So we should draw safety requirements to guarantee system safety for the first time. In this paper. the hazard identification and analysis to derive the safety requirements on the train control system are carried out. To analyze hazard, we have to deduce system functions. identify related hazards, derive the effects of the hazards, analyze current risks. define the target risks of the system, and deduce the alternative plans to reduce the effects of the hazards. For the case study, Preliminary Hazard Analysis(PHA) of the Automatic Train Control (ATC) System for Electrical Hazards are carried out.
