초록

본 논문에서는 위험사건 및 안전사고를 유발할 수 있는 무기체계의 치명기능 및 치명구성품을 식별하는 프로세스을 제시한다. 제안된 프로세스는 MIL-STD-882E 기반의 위험요인 분석(hazard analysis) 방법을 활용하였으며, 허용 불가능한 리스크 수준에 해당하는 위험요인의 안전대책 유형을 확인하여 치명기능 및 치명구성품을 선정한다. 또한 위험요인의 심각도 및 발생도를 정량화하여 우선순위를 제시한다. 마지막으로 특정 무기체계를 대상으로 해당 프로세스를 적용한 사례연구를 수행하였다.

Abstract

This study presents a process for identifying critical functions and critical items of a weapon system that can cause hazardous events and accidents. The proposed process utilizes the hazard analysis method based on MIL-STD-882E to select critical functions and critical items by identifying the types of mitigation measures for hazards that correspond to unacceptable risk levels. It also quantifies the severity and probability of hazards and prioritizes them. Finally, a case study was conducted to apply the process to a specific weapon
