A study on the requirement management system for the railway safety

초록

The risk control is the process of implementing measures to reduce the risk associated with a hazard. In the process, some difficulties are observed as lack of definite structures in requirements, lack of structured mapping, and lifecycle requirements especially for the complicated system such as railway system. With these difficulties, it is necessary to explore requirement management methodologies and develop tools to support requirement management. This paper introduces an approach to requirement management for the railway safety by reviewing the legal requirements. The approach is based on recognizing functional requirement patterns from regulatory requirements and taking into account system with consideration of the lifecycle. To demonstrate the methodology, a database system is developed. The database system improves risk control process with traceability between the identified hazards and safety requirements with the consideration of the system configurations and safety activities. The system could also be used for ensuring a legal compliance of design activities.
