A Study on the Improvement of the TRA Framework for Complex Weapon Systems from the System Integration Perspective

TRA(Technology Readiness Assessment) quantitatively assesses the current level of domestic technology and is used as a key tool for determining possibility R&D risk management. However, since TRA utilizes hardware-oriented TRL(Technology Level), it suitable independent assessment each technologies, but has limitations in evaluation from system integration perspective. In addition, checklist-based highly likely to involve subjective evaluation. This study proposes an enhanced framework by redefining procedures criteria systems perspective engineering. We focused on developing that overcomes TRL/TRA enables easier more intuitive assessment. The proposed distinguishes between TE(Technology Element) CTE(Critical Technology terms HW, SW interface redefines TRL. performed according TRL redefined above three points view, lowest value maturity consideration CTE selection method minimizes intervention evaluator utilizing quantitative goal ROC(Required Operational Capability), development difficulty, application COTS(Common Off Shelf) technology. effectiveness this was confirmed through case TSS(Target Surveillance System). It hoped starting with study, research at will be activated contribute improvement system.
