철도시스템 안전상태 평가·예측 소프트웨어 설계 연구

초록

Separately managed railway operational histories and safety measures hinder the traceability of risk progression and intervention decisions. This study designed software linking four safety-chain stages (risk factors, risk precursors, hazardous events, and consequences) with a current assessment, future prediction, and safety-measure review. The responsibilities, logical inputs, processes, outputs, and exchanges were defined by function. Five components cover risk-factor assessment, safety-chain assessment and prediction, social-impact cost-benefit assessment, safety-measure decision support, and integration and dashboards. The design specifies five linkage types and 22 entities across five data domains. Common identifiers connect the operational records, safety chains, assessment criteria, measures, and results. A hypothetical case traced the inputs, calculations, outputs, and source records. This integrated workflow and data structure supports assessment, prediction, and decision support. The case examined the design-level information flows and assumed-value calculations without validating prediction accuracy or field effectiveness.
