무기체계 건전성 프로그램 기반 시제 항공기 잔존자산가치 평가 모델 개발 및 시뮬레이션에 관한 연구

초록

As a System of Systems (SoS) where physical deterioration and technological obsolescence are intertwined during the R&D stage, prototype aircraft pose significant challenges for accurately estimating substantial residual value through conventional appraisal methods. This study developed system-specific residual value evaluation models using the U.S. Department of Defense Weapon System Integrity Guide (WSIG) and four major integrity programs (ASIP, ENSIP, MECSIP, and AVIP) as the engineering foundation. Specifically, the research designed models incorporating irreversible linear reduction for structures, wear and overhaul restoration (impulse functions) for mechanical and engine systems, and exponential decay alongside obsolescence (step functions) for avionics. Furthermore, by proposing an impairment adjustment model based on the Structural Index (SI), this study confirmed that a more precise valuation is possible compared to the conventional declining balance method based on regulatory useful life. While this methodology supports rational decision-making for prototype asset management, it is limited by the use of simulated data due to military security constraints.
