Abstract

A precedent defense project study was carried out in the early stage of the project to support efficient determination of the acquisition method of the determined weapons system. A precedent study in the early stage of the project has been neglected, but lack of performance and increased costs are continuing problems. In a precedent study on a number of items within a limited time frame, expected risks during project implementation were not identified and reduced by failing to review the key review element in depth. Therefore, in this paper, we studied the application of the FTA/FMEA technique used in the system safety analysis process to identify key factors to be considered when carrying out the defense research project. The methodology for the development of the key review items was established through the improvement of the FTA/FMEA technique in order to meet specific conditions and given conditions. Based on the results of this study, we redefined core key factors in the precedent study stage, thereby eliminating unnecessary and anticipated risks that may arise in the future project management aspects of the defense project. It is anticipated that this will reduce costs and time in terms of the lifecycle of the weapon system and promote stable operation of the project through reduction of risk.

방위력개선사업의 선행연구는 소요가 결정된 무기체계의 효율적인 획득방법 결정을 지원하기 위해 사업초기 단계에 수행되고 있다. 사업 초기단계의 선행연구는 그 중요성이 간과되어 소홀히 진행되어 왔으며, 이로 인한 성능 미충족 및 비용증가 등의 사업추진간 문제점이 지속적으로 발생되고 있다. 제한된 시간내 많은 항목의 선행연구를 수행한 결과, 핵심검토항목을 깊이 있게 검토하지 못함으로써 사업추진간 예상되는 위험을 식별하고 감소시키는 역할을 제대로 수행하지 못하고 있다. 따라서, 본 논문에서는 방위력개선사업 선행연구 단계에서 수행시 고려해야 할 핵심요소들을 식별하기 위해 시스템안전 분석과정에서 사용되고 있는 FTA/FMEA 기법의 활용에 대해 연구하였다. 구체적으로 수행방안 도출시 FTA/FMEA 기법의 적용에 대한 착안점 및 주어진 조건에 부응하도록 개선을 통해 핵심검토 항목 도출을 위한 방법론을 구축하였다. 본 연구의 결과를 토대로 방위력개선사업 선행 연구단계에서 핵심 수행요소 재정립을 통해 향후 방위력 개선사업의 사업관리 측면에서 발생할 수 있는 불필요성 및 예상되는 위험을 제거함에 따라, 비용 및 시간을 절감하고 위험감소를 통한 사업의 안정적 추진을 기대할 수 있을 것으로 기대된다.
