A Study on How to Link the Development of Weapons Systems with the Development of Technologies Using Technology-Product Relevance Analysis

Core technologies based on weapon systems are essential for establishing mid to long term defense technology roadmaps by reflecting the results of weapon system technology analysis. However, a systematic methodology for deriving core technologies remains insufficient. The relationship between weapon systems and core technology R&D must be distinctly analyzed. To address this, the study utilizes a Technology-product Relevance Analysis to examine the relationship between the Work Breakdown Structure(WBS) of weapon systems and their component technologies. This approach aims to reduce technological gaps and enhance the interconnectivity of required technologies within a single weapon system, ultimately contributing to more strategic core technology planning. It derives data that can be used for policy decision-making by applying the system contribution of technologies, the technology requirements of each system, and technology similarity. In particular, by creating a technology relation map through technology similarity information, it provides a basis for easier decision-making on resource and personnel allocation. The study also analyzes domestic and international cases related to this theory and derives implications, presenting verification and insights on its applicability through empirical analysis. The information obtained from technology relationship analysis is provided as objective data for decision-making and is expected to contribute to the efficient use of limited defense budgets in defense science and technology research and development.
