초록

본 연구는 철도차량의 수명주기비용(LCC) 관리 체계를 벤치마킹하여 함정 총수명주기관리의 개선 방향을 도출한다. 기준, 관리 주체, 데이터, 분석 기법, 검증의 다섯 축을 비교한 결과, 철도는 거버넌스 일원화·데이터 표준화·정량 분석·독립 검증이 체계화된 반면, 함정은 정례 LCC 갱신과 표준화가 미흡하고 내부 검증 중심 경향이 뚜렷했다. 이에 관리 체계 일원화, 데이터 표준화 및 정합성 제고, 불확실성·민감도 분석의 상시화, 독립 검증 도입을 제안한다.

Abstract

This study derives directions to improve total life cycle system management (TLCSM) for naval ships by benchmarking the life-cycle cost (LCC) management framework used for railway vehicles. A five-axis comparison—basis, governance, data, analytical methods, and verification—shows that railways feature unified governance, standardized data, quantitative (uncertainty/sensitivity) analyses, and independent verification. By contrast, naval programs lack standardized, periodic LCC updates and rely heavily on internal verification. We recommend unifying the management framework, strengthening data standardization and consistency, institutionalizing uncertainty and sensitivity analyses, and introducing independent verification.
