Global Positioning System(hereafter; GPS) is recently an essential element in the various navigation and weapon delivery systems of military aircraft. However, GPS is vulnerable to the jamming threats since its signal power is very weak. Therefore, ROK defense has been concerning how to resolve this issue and how to integrate these systems needed, and is trying to acquire the proper anti-jamming GPS system. This study is to provide several schemes against the jamming threats effectively. We propose the several processes to analyze the required capability and demonstrate the result's of modeling and simulations(hereafter; M&S) for this integration of military aircraft, and the mathematical programming model for system optimization of military aircraft anti-jamming GPS system on the basis analysis of M&S results which could be considered available budget and the project characteristic. These schemes will be helpful on proper acquisition of these systems and. We are looking forward to contributing to the integration of anti-jamming GPS system of ROK military aircraft.

우리나라는 1983년에 절충교역 제도를 도입하여 국방 전력증강의 효율적 수단으로 활용하여 왔다. 그런데 절충교역은 계약체결이 획득기술에 대한 가치평가 결과를 근거로 이루어지기 때문에 국외업체와의 협상 등 업무과정상 지연될 가능성이 존재한다. 절충교역 계약체결이 지연되면 무기체계 구매사업이 늦어져 국방 전력증강에 심각한 악영향을 주게 된다. 따라서 본 연구에서는 절충교역 계약 과정, 특히 계약 소요기간에 영향을 미치는 요인들을 통계적으로 분석하여 소요기간을 결정하는 요인을 규명하고자 하였다. 영향 요인으로는 국외업체 국적, 사업진행 형태 (경쟁/단독 입찰), 사업 특성 (최초/계속 사업), 최초 제안기술의 수, 국내 무기체계 분야별 국방과학기술수준, 기본사업 규모 등 6개를 고려하였다. 가설 검증은 절충교역 계약이 체결된 25개 사업을 대상으로, 상관분석 및 다중회귀분석을 통하여 이루어졌다. 상관분석 결과에 의하면, 기본사업 규모, 최초 제안기술의 수, 사업 특성 등이 종속변수인 절충교역 계약 기간과 양의 상관관계를 갖고 있음을 알 수 있었다. 다중회귀분석 결과에서는 기본사업 규모와 사업진행 형태가 절충교역 계약 소요기간에 유의한 영향을 미치는 것으로 나타났다.

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.

So far, the existing guideline called "Proposal Evaluation and Negotiation Guidelines for Weapon Systems (PE&NG)" has been employed even when choosing a development firm for the newly-adapted defense acquisition system, "Advanced Concept Technology Development(ACTD)". However, in that PE&NG ignores distinctive characteristics associated with ACTD programs, it is inappropriate. This study aims to propose an appropriate evaluation index which could be used to select the most suitable development company for the successful ACTD project. For this, Delphi techniques were used to collect extensive opinions of the hands-on workers. These opinion were consistently given but never gathered previously. The newly proposed index has a similar direction and range to the existing ones with its contents a little modified and simplified. Yet, it is more capable of evaluating candidates' proposals.

본 연구에서는 군수품 무역대리점과 관련하여 크게 두가지의 연구를 수행하였다. 첫째는 군수품 무역대리점의 활용 효과도를 정량적으로 측정하기 위해 방위사업 종사자들을 대상으로 설문조사를 하였고, 두 번째는 중개수수료의 적정 기준을 제시하기 위해 실제 무기체계 국외구매사업의 사례에서 군수품 무역대리점이 실제로 활동한 내역을 분석함과 동시에 통계청에서 발표한 일반 상품중계업의 평균 영업이익이 군수품 중개업에도 보장될 수 있도록 적용하였다. 그 결과 군수품 무역대리점의 효과도 측면의 설문조사에서는 무역대리점을 활용하는 것이 활용하지 않는 것 대비 1.07배 효과적인 것으로 분석되었다. 적정 중개수수료와 관련된 분석에서는 중/소형사업과 대형 사업에서 상이한 결과가 나왔는데, 중/소형사업의 경우 총사업비의 5.1~8.7%가 적정 중개수수료인 반면, 대형사업의 경우 총사업비의 1.2~1.8%가 적정 중개수수료로 분석되었다. 따라서 본 연구에서는 군수품 무역대리점을 활용시 활용하지 않는 것 대비 어느 정도 효용성이 있는 것으로 확인되었고, 만약 정부가 적정 중개수수료율을 제시한다면 지금까지 논의 되었던 것처럼 고정된 특정 값을 일괄적으로 제시하는 것은 현실적이지 않고 총사업비 규모에 따라서 그 요율을 탄력적으로 적용하되, 사업의 성격을 분석하여 필수 활동비 소요를 사전에 파악하여 가감하는 것이 적절함을 알 수 있었다.

The private sector is currently reviewing the feasibility of the project or deciding economic policies by analyzing the economic ripple effects. However, the arms acquisition project focuses on the need for the national defense weapons system by analyzing the costs and the effectiveness of the analysis and reviewing the necessity and feasibility of the project. In order to analyze the economic ripple effects, KB (the Bank of Korea) prepares and publishes an analysis table of industrial associations in a given unit. IAAR (the industrial association analysis report) is difficult to apply directly to the defense weapons system. Therefore, research on the economic ripple effects applicable to the defense arms procurement project was needed. In this study, we propose the generic methodology for estimating economical and technical ripple effects resulted in acquiring new weapon systems. Based on the analysis of inter-industrial relations, economical ripple effects are estimated with production inducing effects, value-induced effects, employment-induced effects and export-induced effects. Also, the technological ripple effects are estimated with technological intensity represented by investment cost in research and development. To show the validity of proposed methodology, a case study of acquiring new weapon systems such as GR (guided rocket), destroyer, and helicopter is accomplished. From the case study, it is concluded that these economical & technological ripple effects can be used as a reference to decision making in the course of acquiring major future defense weapons systems.

The defense M&S system, which has been classified as a weapon system between requirements determination and project implementation, is being developed by applying the weapon system development procedure of the Defense Acquisition Program Administration. The M&S system abstracts and models the real world to suit the intended use and proceeds with the process of developing it as a software-oriented system. Overseas, the conceptual model development stage is staged before entering the design stage after the requirements analysis. In addition, each step includes verification and validation processes. In Korea, while establishing and applying the weapon system development procedure based on the SE process, the M&S system is also applied in the same way as the general weapon system, limiting appropriate development outputs and verification and validation. In this study, the system development procedure of the M&S system is established and presented based on the relevant standards and SE process of developed countries.

In general, similar or previous projects are mainly referred to in order to derive operational test and evaluation(OT&E) items after acquiring weapon system. The idea that a more systematic method is needed is spreading because some of OT&E items derived in this process are redundant or unnecessary. Therefore, in this topic, we plan to use WBS, a tool that classifies components into a hierarchical structure and manages development easily to achieve the weapon system development goal. In addition, the WBS tool is applied to the medium-sized standard vehicle project, which is currently being research and developed, to effectively derive OT&E items. As a result of deriving OT&E items by applying WBS to the vehicle development field and electric devices of the medium-sized standard vehicle project, the operability and relationship were judged early, and then contents of the evaluation items could be written substantially while working on environmental adaptability. In the future, it is judged that the efficiency will be increased if the method discussed in this paper is applied when deriving the OT&E items from the R&D development project.

The PMB(performance measurement baseline) is the total time-phased budget plan against which program performance is measured. Additionally it is the schedule for expenditure of the resources allocated to accomplish program scope and schedule objectives, and is formed by the budget assigned. In this paper, we suggest an improvement of the R & D(research and development) program for defense acquisition by using the PMB and an application of the IBR(integrated baseline review) to review the PMB for project manager of the defense agency.

The research and development stage can improve the goal level of the project through systematic operation and management of systems engineering. The test evaluation tasks in the R&D process have a lot of connections with the system engineering in terms of requirement management, and the methodology for deriving the requirements when establishing the test evaluation items has been consistently required. In this paper, we propose the process of effectively establishing and using QFD (Quality Function Deployment), a tool to manage customer requirement, and drawing up HOQ (House of Quality) in the search and exploratory development stage of the self - propelled mortar project.
