Abstract

Owing to the complexity and modernization of weapon systems, the role of the defense industry in producing military companies has become increasingly important. In the past defense industries, price competitiveness is a key factor in product choice. On the other hand, product quality is becoming increasingly important compared to price competitiveness. In particular, improving the quality efficiency of small and medium defense suppliers is a necessary part of realizing completed weapon systems, and measures are required to evaluate the quality efficiency of small and medium defense suppliers objectively. This study measured the efficiency of quality using DEA, which is one of the decision methodologies. To use DEA, the number of employees (QA Team) and the number of improvement requirements (Through the activity of onsite quality-support team in aeronautical system center) were set as the input variables. In addition, the output variables were based on sales and the number of certification acquisitions (QMS). To analyze the quality efficiency of small and medium defense suppliers in the aeronautical field, both CCR and BCC models were analyzed, and the scale efficiency values were derived. Strategic development plans for small and medium defense suppliers can be guided using the research results.

무기체계의 복잡성과 현대화로 인해 군수품을 생산하는 방산업체의 역할은 점점 더 중요시되고 있다. 과거 내수 위주의 방위산업은 가격 경쟁력이 제품 선택의 주요 요소였다. 하지만, 오늘날 가격 경쟁력 보다는 제품 품질의 중요성이 대두되고 있는 실정이다. 특히 방산 중소 협력업체의 품질 효율성 향상은 완벽한 무기체계 실현에 반드시 필요하며 국방분야 중소 협력 업체의 품질 효율성을 객관적으로 평가 할 수 있는 방안이 필요 시 되고 있다. 이에 본 연구에서는 의사결정 방법론 중 하나인 자료포락분석기법 (DEA)를 활용 하여 국방산업의 항공분야 중소 협력업체 품질 효율성을 측정하고자 한다. DEA 분석을 위한 입력변수로 종업원수(품질부서), 개선사항건수(항공센터 현장품질지원반 활동)로 설정하였으며, 출력변수로 매출액 및 인증획득수(품질경영시스템 등) 설정하였다. 항공분야 중소 협력업체의 품질 효율성 분석을 위해 CCR 모형과 BCC 모형을 모두 분석하였으며 규모 효율성 값을 도출하였다. 분석 결과를 바탕으로 국방산업 항공분야의 중소협력업체 품질 효율성을 저해하는 원인을 도출 하였으며, 향후 개선 및 발전 방안을 도출하였다.
