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.

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.

The problem of establishing weapon system safety especially during the development process has been one of the very important fields related with public safety in advanced countries such as USA, UK and so on. These countries have launched strong policies on system safety to reduce the chance of accidents. However, the Republic of Korea (ROK) has limited experiences and application of the system safety on domestically produced weapon systems. Therefore, it is imperative that the government starts a comprehensive and systematic policy on system safety to reduce the occurrence of potential accidents during the development of weapon systems. In this paper, we analyze system-level activities needed through the life-cycle of the weapon systems and provide a suggestion for application of the system safety.

다표적-다무장 전장 환경에서는 다수의 무장이 동시에 발사되기 때문에 무장 간의 궤적 교차로 인한 충돌이 발생할 가능성이 항시 존재한다. 무장간 충돌은 신속한 작전 수행을 저해할 뿐만 아니라 아군 무장 자산을 무의미하게 손실시킴으로써 아군의 적군에 대한 위협 대응력을 약화시킨다. 본 논문에서는 다표적-다무장전장 환경에서 무장 궤적 간 교차 검증 및 간섭 배제 알고리즘을 제안한다. 제안하는 알고리즘은 무장 궤적 간 교차 분석을 통해 간섭 여부를 확인 한 후, 교차점이 발생할 경우 무장 궤적 간의 상호 간섭을 배제하는 것을 핵심으로 한다. 본 논문에서는 제안하는 알고리즘의 시뮬레이션 및 가시화를 통해 성능 평가 및 검증을 수행하였다. 성능 평가 결과 제안하는 알고리즘은 표적 수 및 무장군 수와 무관하게 교차점이 존재하지 않음을 보여줌으로써 효과적인 간섭 배제를 수행함을 입증하였다.

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.

Purpose: In this study, we propose that how to approach a effective system engineering and optimize system engineering management process for the mass production weapon system parts localization development process and success in DTaQ. Methods: To approach a effective system engineering for the mass production weapon system parts localization, we analyze a weapon system acquisition process and system engineering process of Republic of Korea and DTaQ parts localization business regulations in advance. after results of analysis of them, we implement a optimized parts localization development system engineering based on ISO/IEC/IEEE 15288. Results: In order to apply International Standard ISO/IEC/IEEE 15288 to the mass production weapon system parts localization development process, we compare the mass production weapon system parts localization acquisition environment with ISO/IEC/IEEE 15288 and analyze them. therefore, It is possible to implement a part of concept stage and development stage of ISO/IEC/IEEE total life cycle stage for the mass production weapon system parts localization development process. To achieve the technical review milestones of DTaQ parts localization business regulations in the selected stages of ISO/IEC/IEEE, the development and management agency perform 2 high rank process and 19 low rank process specified in ISO/IEC/IEEE. Conclusion: When the development and management agency perform the mass production weapon system parts localization development using the proposed system engineering approach, they should easily meet milestone through the clarified requirement and simplified System Engineering output documents in limited development period.

무기체계 효과도 분석을 위한 국방 M&S(Modeling & Simulation) 분야는 실 전장 환경과 유사한 무기체계 실험 환경을 제공하는 현실적인 수단으로 인정받고 있다. 그러나 무기체계에 대한 모델을 구축하기 위해서는 많은 시간과 비용이 필요하며, 이에 따라 기 개발된 모델을 재사용하려는 요구가 있어왔다. 본 논문에서는 기 개발된 모델의 재사용을 장려하기 위해 온톨로지 기반 국방 M&S자원 클라우드 저장소인 OB-Cloud(Ontology Based-Cloud Storage)를 제안한다. 본 논문의 구현물은 무기 체계 효과도 분석 과정을 지원하는 통합시뮬레이션 엔진인 OpenSIM(Open Simulation engine for Interoperable Models)에 적용되었으며, 온톨로지 및 시소러스를 고려하여 재사용 가능한 모델에 대한 의미기반 검색을 지원한다. 본 논문에서는 국방 M&S 개발자가 작성된 모델을 OB-Cloud에 등록하고 국방 M&S 사용자가 OB-Cloud에서 본인이 원하는 국방 M&S 자원을 검색하여 새로운 모델 개발에 사용하는 예제를 통해, 유사 M&S 자원 간 재사용성이 증진될 수 있음을 보이도록 한다.

무장통제 소프트웨어는 무장체계와 연동하여 함정 전투체계 내 무장 운용을 지원하는 기능을 수행한다. 무장통제 소프트웨어는 무장체계에 의존적이므로 연동 정보 변화에 따라 소프트웨어 수정이 필연적으로 이뤄지는 특성을 가진다. 소프트웨어의 수정은 신뢰성 시험과 같은 검증 단계를 반드시 거쳐야 하므로 개발 비용의 상승을 초래한다. 본 논문에서는 기존 무장통제 소프트웨어의 수정 요소를 최소화하기 위해 무장통제 소프트웨어 표준 아키텍처를 설계하였다. 연동 정보 관리를 위해 휘처 모델(Feature Model)로 공통요소와 가변요소를 구분하였고 디자인패턴 중 전략 패턴(Strategy Pattern)을 적용하여 소프트웨어 구조를 개선하였다. 소프트웨어 평가 실험을 통해 제안한 아키텍처가 기존 무장통제 소프트웨어보다 개발 비용이 감소하고 변경용이성과 재사용성이 향상된 것을 확인하였다.
