COEA를 활용한 무기체계 기술가치평가 방법론: RAM-C 목표설정을 통한 실증 연구

초록

Conventional technology valuation methods are challenging to apply to defense weapon systems due to the defense market's closed and security-driven nature. To overcome this limitation, this study proposes an integrated technology valuation methodology that connects Cost and Operational Effectiveness Analysis (COEA) with Reliability, Availability, Maintainability–Cost (RAM-C) target setting. We developed a simplified model illustrating the interrelationships among availability, survivability, combat effectiveness, and life cycle cost, and applied the Design Science Research Methodology (DSRM) to create a framework for converting key analytical effectiveness indicators into monetary value. Empirical results show that the effectiveness of these principal indicators can be translated into monetary value, with availability having the most significant impact on the Cost-Effectiveness Ratio (CER). Moreover, by redefining RAM-C indicators as variables for economic value creation rather than solely as design targets, and by utilizing CER-based relative comparative evaluation, this study lays the groundwork for objective decision-making in RAM-C target setting that explicitly integrates economic considerations.
