초록

체계의 신뢰도 향상을 위한 활동으로 고장 보고, 분석 및 고장 수리체계 (FRACAS: Failure Reporting, Analysis and Corrective Action System)가 다양한 산업 분야에서 적용되고 있다. FRACAS는 식별된 고장에 대한 원인 분석과 적절한 시정 조치, 결과 검증을 반복 수행하는 활동으로 신뢰도 향상에 효과적이지만, 기존의 개발 환경에 통합 운용하기에는 프로세스, 데이터 수집 및 관리 등 여러 가지 측면에서 제약사항이 있다. 국내 방산분야에서는 FRACAS 적용의 어려움을 해소하기 위해서 FRACAS 시스템 개발 및 프로세스 개선에 관한 연구가 진행되었지만, 대부분이 운용/유지 단계에 집중되어 있다. FRACAS는 총 수명주기 체계관리(TLCSM: Total Life Cycle System Management) 관점에서 운용되어야 하므로, 개발 초기인 설계 단계부터 FRACAS를 적용할 수 있도록 참조 아키텍처에 대한 연구가 필요하다. 본 논문에서는 국방 무기체계의 전 수명주기에 걸쳐 FRACAS를 효과적으로 적용하기 위해, 체계 수명주기 단계와 FRACAS Closed-Loop 프로세스, FRACAS 필수 요소 등을 고려한 TLCSM 기반의 통합 아키텍처 구축에 대해 연구하였다. 제시된 아키텍처는 함정 전투체계 사업에서 FRACAS 수행 시 참조 모델로 활용하였다.

FRACAS(Failure Reporting, Analysis and Corrective Action System) has been applied in various industries to improve the reliability of the systems. FRACAS is effective in improving reliability by repeating failure analysis, proper corrective action, and result verification for identified failures. However, FRACAS has many limitations in terms of process, data collection and management to be integrated into the existing development environment. In the domestic defense industry, studies on the development of FRACAS system and process improvement have been conducted to solve the difficulties of applying FRACAS, but most of them are concentrated in the operation/maintenance phase. Since FRACAS should be conducted in consideration of TLCSM(Total Life Cycle System Management), it is necessary to study the reference architecture so that FRACAS can be applied from the early design phase. In this paper, we studied the TLCSM-based integrated architecture considering the system life cycle phases, FRACAS closed-loop process, and FRACAS essentials in order to effectively apply FRACAS throughout the life cycle of defense systems. The proposed architecture was used as a reference model for FRACAS in a shipboard combat system.
