최근 들어 국방 분야 무기 시스템의 연구개발은 점차 대형화, 복잡화 그리고 장기화하고 있으며, 그에 따라 예산 및 개발 기간도 증가추세이다. 이러한 문제를 개선하기 위해 국방 분야에서는 민간분야의 예비 타당성 제도를 벤치마킹하여 전력소요검증위원회를 설치 운영하여 소요의 적절성, 사업의 추진 필요성 및 우선순위 등을 검증하는 업무를 수행하고 있다. 이에 본 연구는 무기체계 개발의 효과적인 개발 우선순위를 결정하기 위한 방법론을 제안하고자 있다. 첫 번째로 국방 분야의 연구개발을 평가하기 위한 평가 요소들을 기존 연구결과 및 국내 실정을 고려하여 선정하였으며, AHP 기법을 사용하여 기술적인 위험 및 수익성 차원에서 평가 요소들의 가중치 값을 구하였다. 또한, 연구개발 사업인 32개 무기체계에 방법론을 적용하고 결과를 위험성과 수익성 차원의 4가지 분류로 분석해 보았다. 결론적으로 기존 방법론에서는 간과할 수 있었던 수익성 차원의 분석이 가능해 짐에 따라 위험성이 높더라도 수익성이 높은 사업에 대한 재검토가 가능해졌으며 전략적인 국방연구개발 예산의 배분이 가능해졌다.

IT convergence technology can boost the advancement of weapon systems and efficient operation for the military reformation in Korea. This study investigated IT firms' concern about the defense acquisition process for IT-convergent systems and the role of IT firms in the process with Focus Group Interview and in-depth interview on executives of IT firms, and classified the concern to three major issues. They are the clarification of IT firms' role in the defense IT-convergent efforts, the establishment of the control tower for defense IT convergence, and reasonable estimation of software development cost in the defense acquisition process.

This paper describes the quality attributes of an integrated simulation software for weapon systems named Advanced distributed simulation environment(AddSIM). AddSIM is developed as a key enabler for Defense Modeling & Simulation(M&S) systems which simulate battlefields and used for battle experiments, analyses, military exercises, training, etc. AddSIM shall provide a standard simulation framework of the next Defense M&S systems. Therefore AddSIM shall satisfy not only functional but also quality requirements such as availability, modifiability, performance, testability, usability, and others. AddSIM consists of operating softwares of hierarchical components including graphical user interface, simulation engines, and support services(natural environment model, math utility, etc.), and separated weapon system models executable on the operating softwares. The relation between software architectures and their quality attributes are summarized from previous works. And the AddSIM architecture and its achievements in the aspect of quality attributes are reviewed.

Since military weapon accidents or breakdowns are directly linked to enormous damage, it is important to analyze the causes of weapons system accidents. Recently, in the defense sector, there have been cases in which budget has been saved through analysis of the causes of frequent breakdowns and improvement activities that have occurred in the process of operating weapon systems since 2015. But due to the nature of the defense sector, it is not easy to collect data and studies on weapons system accidents have been insufficient so far. Therefore, this study aims to investigate the causes and types of military weapon accidents by collecting military weapon accident data for military weapon systems and analyzing trends by weapon system classification through the analysis process. It analyzes statistically and visually through social network analysis, NodeXL. It is expected that this study will help improve the stability of the weapon system by reducing the number of military weapon accidents and failures.

Demand for performance analysis is increasing for efficient use of limited budgets such as improving investment efficiency and strategic budget allocation in accordance with the continuous increase demand of R&D budget for developing advanced weapon systems in the future battlefields. In accordance with the Act on the Performance Evaluation and Performance Management of the National R&D Projects established in March 2006, the performance analysis has been conducted for the systematic management and utilization of the R&D project performance. It was recognized as a project to achieve self-defense through strengthening the weapons system development capability, however, efficiency evaluation of Defense R&D projects was not much emphasized. Research on the efficiency analysis of defense R&D projects has been conducted in recent years, but most studies focused on corporate efficiency and productivity of defense companies. In this study, we analyzed the three-stage performance of defence R&D projects based on the logical model using the data envelope analysis(DEA) model. We also analyzed performance analysis from various perspectives through R&D type, technology classification and performance model. This study is expected to help defense department improve defense R&D projects and make decision.

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.

Rapid, early, accurate detection and identification of the various pathogenic agents associated with the development of biological weapons is critical in preventing loss of life and limiting the impact of these organisms when used against civilian or military targets. The aim of this study was to produce a system for the simple, rapid, accurate and simultaneous detection and identification of Ricin, Botulinum toxin B and Staphylococcal enterotoxin B as a proof of principle for developing field appropriate reverse transcription loop-mediated isothermal amplification systems for the accurate identification of potential biological threats. These systems were designed to facilitate the identification of potential threats even in remote or resource-limited locations.

군사적 목적으로 많은 레이다들이 근거리에서 동시에 운용된다. 특히, 동종의 레이다가 동시에 운용될 경우 주파수 할당을 해야 한다. 많은 레이다가 동시에 운용될 때 일부 주파수를 공유하여야 하는데, 부득이하게 레이다 시스템 간 간섭이 발생하게 된다. 레이다간 간섭은 성능을 저하시킬 수 있기 때문에, 간섭 신호의 억제는 중요한 문제이다. 본 논문에서는 두 대의 FMCW 레이다간 간섭 신호를 분석하고, 간섭 신호를 이용하여 레이다간 시간 동기화 방법을 제안하였다. 실제 레이다 시스템을 통해 제안된 방법의 성능을 검증하였다.

This paper addresses the maintenance optimization problem in multi-component systems in which parts are connected in series, carrying out several missions interspersed with scheduled finite breaks. Due to limited time or resources, maintenance actions can be only carried out on a limited set of components. The decision maker then has to decide which components to maintain to ensure a pre-specified performance level during next mission. Most of the existing models in the literature usually assume only one system and enough spare parts. However, there are situations in which maintenance is required for multiple systems of the same type. To overcome this restrictive assumption, this study optimizes the maintenance problem considering the lack of repair parts and cannibalism for many identical systems. This study presents two optimization models with different objectives to solve the problem and analyzes the results so that the decision maker can decide. The results of this study are expected to be used for the maintenance of multiple systems of the same type, such as swarm drones.
