This paper describes a development of the operational architecture of a low altitude air defense automation system using a systems engineering approach. The future battlefield is changing to new system of systems that command and control by the network based BM/C4I. Also, it is composed of various sensors and shooters in an single theater. Future threats may be characterized as unmanned mewing bodies that the strategic effect is great such as UAVs, cruise missiles or tactical ballistic missiles. New threats such as low altitude stealth cruise missiles may also appear. The implementation of a low altitude air defense against these future threats is required to complex and integrated approach based on systems engineering. In this view, this work established an operational scenario and derived operational requirements by identifying mission and future operational environments. It is presented the operational architecture of the low altitude air defense automation system by using the CORE 5.0.

국방 정보분야의 효율 효과적인 개발 및 운용을 위해 통합과 표준의 설정 등을 통한 상호운용성 확보가 요구된다. 상호운용성 표준화 기술은 전사적 아키텍처 기반 상호운용성 조정 통제, 플랫폼 중심의 상호운용성 확보를 위한 공통운용환경 및 데이터공유환경 구축에서 시작하여, 현재에는 네트워크 중심 환경에 적합한 SOA(Service Oriented Architecture) 기반 상호운용성 증진 전략으로 패러다임이 변화하고 있다. 미군의 경우 단일체계 관점에서 복합체계 관점으로 확대 적용을 위하여 기존의 공통운용환경 및 데이터 공유환경을 SOA 기반의 NCES(Net-Centric Enterprise Service)로 전환을 추진해왔다. 또한 이와 병행하여 미 육군 수준에서는 전쟁을 수행하는 각 객체를 컴퓨팅 환경으로 구분하여 육군 차원의 공통운용환경을 구축하고 있다. 이에 본 고에서는 국방 공통운용환경의 동향을 미군의 사례를 중심으로 살펴보고 시사점을 도출한다.

Recent modeling and simulation technology is being used in various fields. Especially in the field of military, Simulation-Based Acquisition (SBA) is recognized as a essential policy. To effectively carry out SBA, modeling and simulation techniques should be applied in the whole life-cycle for the weapon system development, and simulation architecture framework which provides easily reusable and interoperability is needed. Through reusability and interoperability, the costs of constructing the integrated collaborate environment for simulation based acquisition can be minimized. In this study, we define requirements, issues for enhancing reusability and interoperability, and propose simulation framework as a solution of the problem including structural design. Proposing simulation framework provides common functions for producing simulator as reusable units and easily changeable structure on user's purpose. In addition, we provide the result for applying simulation framework to our project.

In the component assembly and composition technique of software architecture, It is operated that the existing composition techniques based on architecture, ACME, Wright etc., used in FIFO with the direct connection structure between components through connector's Role. But, when the non-synchronizing request of components that have different characteristics occurs, the FIFO techniques is applied to the connector is difficult to process and operate effectively because of the high performance component waiting the sequence order if the low performance component is allocated first. Thus, the allocated request process according to the priority considering the characteristics of each call components in connector is necessary to improve the operation of assembled component. In this research, we extend the connector part that is available in multiplex connection structure based on existent Wright specification. For service process requested from component, the connector part is designed and implemented to operating with priority sequence through calculating the weight of CPU use rate, bean requesting process time and memory use rate among the efficiency elements of assembled components. To verify the efficiency if this designed connector, we implemented 20 samples EJB components that have different efficiency characteristics and applied these samples components to designed connector. The operating results with this designed connector show that the efficient operation of whole system is possible though the processing time takes 481ms more than the time of the existing FIFO techniques.

The US DoD architecture framework defines architecture Products according to three viewpoints : operational view, system view, and technical view. But, its coarse-grained development process causes leakage of the details In transforming among different views. It also uses different methods for architecture products development, so that the levels of those products are not consistent. So. we propose MND AF(Ministry of National Defense Architecture Framework) for military environment to solve those problems. We propose additional architecture products to achieve consistency, including “architecture disciplines definition description,”“organization-to-activity relationships matrix,” “system definition description,” and “technical reference model,” etc. We also propose the architecture development process in more detail through seven steps. In addition, we propose the applicability of those products to the life cycle processes of the acquisition management. MND AF can provide consistency and traceability of architecture products, provide the basis for sl·stem integration and interoperability. Also, architecture developers can construct architecture in a more effective and efficient way through MND AF.

The Korean naval weapon systems, combat experiments establish the concept of Battle operations, and create the future of the new weapons system. Doctrine development and training as well as ranging from experiments for evaluate the performance of mission operations for combat experiments are used. The battle lab is effectively support tool for the Korean Naval battle experiments. The battle lab is through a dedicated testing facility and to build efficient and effective simulation-based acquisition supporting environment. In this paper, the ship / submarines C2 operations virtual simulator was developed to support the concept of Battle operations of naval combat experiments in training and tactical development. The ship C2 operations virtual simulator makes the anti-ship and anti-aircraft the engagement scenario for performed experiments using the SADM. The submarines C2 operations virtual simulator makes the anti-submarine engagement scenario for performed experiments using EAS. EAS System was created before reuse. EAS system by modifying the additional interfaces HLA-RTI has been reused. Reflected in the tactics and training after analysis of the results through the battle experiment. Also increase training fidelity through operator involvement. The anti-ship and anti-aircraft system architecture (SADM) and anti-submarine system architecture (EAS) requires unique design of system framework since two separate architectures should be integrated into a system. An C2 virtual linked architecture was used to integrate different system architecture. A C2 virtual linked software framework, designed that have integrated protocol for battle experimental linkage and battlefield visualization environment.

CBD를 지원하는 소프트웨어 개발기법이 최근 많은 관심과 함께 도입되면서 이를 효과적으로 운용할 수 있는 아키텍처기반의 조립 및 활용분야가 활발히 연구되고 있다. 특히, C2(Chiron-2) 스타일 아키텍처는 GUI를 지원하기 위한 메시지방식의 컴포넌트 조합기법이라는 점에서 많은 관심을 받고 있다. 그러나, 서버측 컴포넌트 모델인 EJB(Enterprise Java Beans)의 경우 쓰레드를 포함할 수 없으며, 직접적인 메소드를 호출하는 방식으로 이하여 GUI 기반 메시지 방식에서는 수정이 불가피하다. 따라서, 본 논문에서는 C2 스타일 아키텍처에 EJB 컴포넌트를 적용할 수 있는 기법을 제안하고자한다. 즉 디자인패턴 중 구조패턴의 하나인 Adapter패턴을 이용하여 EJB 컴포넌트를 C2 프레임워크에 적용할 수 있는 컴포넌트 쓰레드로 생성 및 운영하였다. 이를 위하여, J2EE 1.2.1과 J2SDK1.3환경에서 구현 및 실행하였다.

In this paper, we have proposed Architecture Development methodology which can connect both operational view and system view. The Functional Architecture can connect both user and developer, and it is located between Activity analysis and System analysis. We suggest the new architecture methodology using the Functional Architecture and it provides effect to analyze the connection between user(military) and developer(enterprise) in Defence R&D and the new Architecture with the feedback analyze activity on a point of system view and the new architecture make the functional architecture.
