The Requirement Development Process for Urban Transit System using Model Based System Engineering

초록

The Urban Transit is complex system which consists of vehicle and infra such as electric power, signal, and track. The system is more complex introducing manless driving recently. Design mistakes might happen because system is complex, therefore, there is need to reduce error in a basic design stage. System engineering methods are introduced to reduce design errors in space-air, national defense research area, also system engineering methods are introduced to reduce design errors in railway engineering recently. Even there is application method of system engineering in ISO 15288, it is hard to follow ISO regulations as stated in ISO regulations because it requires much time and cost. To reduce time and cost unique system engineering methods for railway engineering should be applied and one of them is analysis of system requirements.
