Weapon systems are curcial instruments for the security of a nation and critical elements for the victory in a war. Since modern weapon systems tend to be capital-intensive with high precision and quality, they become more and more complex and diversified; their acquisition costs become huge; and their technological obsolescence becomes accelerated. Therefore, the systematic management of weapon acquisition process would be one of the most important defense tasks at the national level. To analyze such problems and find solutions, this paper has studied various aspects related to the efficient management of weapon system acquisition. After brief summarization of the general characteristics of weapon systems, their effectiveness, and developmental trend, the paper discusses the defense management policies and techniques for the weapon systems. Specifically, four alternative acquisition methods such as indigenous R & D, foreign purchase, co-production and joint-production are discussed and analyzed by systems approach. The systems analysis procedure to evaluate and select weapon acquisition method is as follows; 1) to analyze the merits and demerits of the alternative methods, 2) to screen unrealistic alternatives through the consideration of significant factors such as political, economic, military, technological, and social constraints, 3) to evaluate and select an optimal one among the remaining acquisition methods after the cost-effectivenss analysis. For the base of cost-effectivess analysis, cost analysis model as well as effectiveness analysis model of each acquisition method are developed.

무기체계의 획득은 획득과정 초기단계에서 시험평가 자료의 원천으로 모델링 및 시뮬레이션의 사용이 적극적으로 권장되고 있다. 이와 같이 무기체계의 획득에 있어서 신뢰성은 가장 중요한 부분 이라할 수 있고, 이를 위해 M&S를 적용하여 시험평가의 신뢰성과 정확성을 제공할 수 있으며, 시험에 소요되는 시간과 비용의 절감, 사전 예측 및 사후 검증등이 가능한 자료를 제공할 수 있다. 따라서 본 연구에서는 M&S의 이론적인 고찰과 무기체계의 획득을 위한 M&S 활용의 중요성, 획득모델의 특징, 무기체계 획득을 위한 활용실태 등을 고찰하여 효과적인 무기체계 획득을 위한 M&S의 활용방안을 찾고자 한다.

The Systems Engineering method is increasingly recognized as a central in the Acquisition of Weapon Systems in South Korea. Because of these trends, issues concerned with improving weapon system design are increasingly raised. This paper presents a development of Operational Mode Summary/Mission Profile (OMS/MP) in terms of Weapon Systems Acquisition for application to Systems Engineering method. For a systematic approach, a precise concept of OMS/MP is derived by analyzing the concept of conventional OMS/MP. This paper reviews the results of a series of previously reported examples aiming to develop the OMS/MP of a weapon system. Based on this, the limitations of the conventional OSM/MP applications are investigated. And these limitations can be resolved by the Fundamentals of Systems Engineering. Finally, the OMS/MP framework based on the Fundamentals of Systems Engineering has been proposed and is successfully implemented for the Harbor Underwater Surveillance System.

Due to the population of the Republic of Korea is getting less, the shortage of available troops has become a big issue. In response to this, the need for Unmanned weapon systems is rising. To operate an Unmanned weapon system near borderlines or low altitude, it is necessary to protect not only the system itself but also operational information communicated between the Unmanned system and control station, so that they should be safe using Cybersecurity measures. Besides, it is critical to protect a few core technologies applied to Unmanned weapon systems throughout the Anti-Tamper measures. As the precedent studies only focus partially, Cybersecurity or Anti-Tamper, it is acknowledged that comprehensive studies are needed to be conducted. This study is to incorporate both concepts into Korea's defense acquisition process. Specifically, we will outline the concepts and needs of Cybersecurity and Anti-Tamper, and briefly present ways to apply them simultaneously.

최근 획득방안 도출을 위한 선행연구 조사 분석의 객관성 및 신뢰성이 확보된 과학적 결과에 대한 요구가 증대되고 있다. 이러한 요구에 따라 획득방안 연구 방법론에 대한 검토가 진행되고는 있으나, 아직까지는 초기 단계이며 비 전문적인 실정이다. 본 연구에서는 실무에 활용할 수 있도록 일반적인 의사결정 방법 및 국가 연구 개발 사업 의사 결정 방법, 현재 활용 중인 AHP(Analytic Hierarchy Process), ANP(Analytic Network Process), KAAM(Knowledge-based Alternative Analysis Model) 등의 무기체계 획득 방안 연구 방법론 등을 비교하여 무기체계 획득방안 연구에 가장 적합한 AHP 기법을 방법론으로 제안하였다. AHP 항목으로 비용, 효과, 전력화 시기, 사업 관리 위험 등의 종합적인 요소들을 비교 분석함으로써 무기체계 획득방안 연구의 객관성과 신뢰성을 높이고, 정량적인 비교 분석으로써 과학적인 결과를 도출하였다. 본 연구를 통해 AHP를 활용하여 보다 무기체계 획득방안을 과학적이고 정량적으로 비교 분석할 수 있게 기여하였다.

The performance of weapon system, based on the acceleration of advanced scientific technology, has been reinforced to the state of precision, complexion and multi-function. People have given great interest for a long time on its development, acquisition cost and enormous expense of operation/support. Under this environmental situation, this research paper proposes two kinds of implementation that can improve the RAM(Reliability, Availability, Maintainability) on weapon system. The first section is to understand all of the actual states on its reliability, in the acquisition process and to make the improvement for RAM at the milestones on the acquisition steps. The next section is to establish a defense RAM center, which will be closely cooperated with acquisition organization such as Ministry of Defense, DAPA(Defense Acquisition Program Administration), DTaQ(Defense agency for Technology and Quality) and ADD(Agency for Defense Development), etc. and to conclusively improve the RAM of weapon system in South Korea.

본 연구는 무기체계 획득의 신뢰성과 연구개발의 효과를 증대하기 위한 모델링과 시뮬레이션 방법을 전산유체역학을 이용하여 연구하였다. 모델링과 시뮬레이션을 이용한 시험 평가가 무기체계의 획득에 신뢰성을 줄 수 있고, 시험에 필요한 시간과 비용의 절감, 사전에 예측하고 사후에 검증이 가능한 자료를 제공할 수 있다. 그러나 현재 우리의 무기체계 획득에서는 모델링과 시뮬레이션을 적극적으로 활용하지 않고 있으며 검증을 위한 소프트웨어 사용도 제한되고 있는 실정이다. 따라서 본 연구에서는 전산유체역학을 이용한 모델링과 시뮬레이션을 위해 GAMBIT과 FLUENT를 이용하여 모델링과 시뮬레이션을 실시하였다. 그 결과 기존의 연구보다 더 좋은 결과 확인하였고 향후 무기체계의 획득과 연구개발에 많이 활용될 것으로 기대된다.

The Core in Weapon system R&D is to realize the user required capabilities in limited schedule and cost. Therefore, the design of weapon system focuses to functional design for realization of requirement capabilities. However, the weapon system should not only basically bring the confidence to friendly forces bring fear to enemy forces to maximize the operational effectiveness of weapon systems and we consider the exterior design as the important factor to compete with foreign systems in international defense market besides capabilities and cost. For that reason, we made study case about the visual design decision process applied to the LVT(light tactical vehicle) project which was recent successful deployment among the many R&D projects of auto industry. Based on this case, this study suggests the necessity of the exterior design decision process the maneuver weapon system is developed.
