철도 화재안전 대책의 중복성 검토를 위한 모델 개발연구

초록

In order to improve safety performance in railway system, various safety measures cam be applied for a single accident. For example, about 140 fire safety measures can be applied in the field of rolling stock, infrastructure, operation, and staff management. Estimating effects of each safety measures are not easy because each safety measure have correlations among them. For the efficient use of resources and systematic decision making a model for redundancy check for safety measures are proposed in this study. The model is based on Fault Tree and Event Tree. Case studies have been done for verification of the model.
