국내에서는 고도의 정보인프라 구축을 위한 광대역통합망(BcN) 추진에 대한 관심이 점점 높아져 가고 있다. 한편, 미래의 전쟁수행개념은 정보우위 확보를 위한 네트워크 중심의 전투(Network Centric Warfare)수행이며 이러한 전쟁수행패러다임 변화에 대응하기 위한 통합망 연구가 중요하나 아키텍처 모델 제시 등 D-BcN을 위한 연구실적은 미흡한 실정이다. 따라서 본 논문에서는 D-BcN에 대한 하나의 아키텍처를 모덱링 하고자 한다. 이를 위해 BcN 개념 및 구조, 외국군 사례, 현 국방 정보통신망 문제점 분석을 통해 국방아키텍처 프레임워크(MND-AF) 지침에 의한 개발방법을 적용, 최상위 운용 및 체계관점에서 하나의 아키텍처 모델링을 제시하였다. 그리고 상용 BcN과 비교하여 주요 차이점을 제시하였다. 이러한 D-BcN 아키텍처 모델링은 보다 구체적인 D-BcN 아키텍처 설정에 도움이 될 것으로 기대된다.

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.

The ROK military has established the MND-AF (Ministry of National Defense- Architecture Framework) and is applying it when developing architecture for Enterprise (MND), Segment (component) and Solution (weapons and force support system). The AMM (Architecture Meta model) of the MND-AF supports the establishment of interoperability by systematizing the architecture information structure defined by the Architecture artifact, describing the relationship between data and also by liking reference models and Information technology standard, common components, and MND-Meta data. which are interoperability standards. However, the MND-AMM has insufficient linkage with the standards, which places constraints on applying interoperability standards when developing Solution architecture. This study suggests a logical data model (OV-7c) from the MND-Meta-data-based Architecture meta model that will enhance the application of MND meta data managed by the MND interoperability standard when developing Solution architecture.

As system is larger, and technology evolves, the system gets complicated due to its integration and heterogeneity of system components. To address its complexity and to accomplish efficient system development, various methodologies have been developed. MBSE using Models and tools is one of methodologies. MBSE methodologies and its products are differently applied according to the organization and project. It is proper that unique methodology is applied in a development of single system. But what if a variety of methodologies are applied in the same domain or SoS development, it will cause a confusion of communication and waste of engineering efforts. As a way to resolve this, it can be considered that MBSE using architecture framework that clearly define products. In other words, by taking advantage of that an architecture framework provides the type, representation and meta-model of products, the reusability and universality of MBSE products can be improved.

Architecture framework (AF) is a guideline to define components needed to develop and operate enterprise architecture (EA), and to define relationships among the components. There are many architecture frameworks to operate EA of governments and businesses such as Zachman framework, DoDAF, TOGAF, FEAF, and TEAF. DoDAF is the most representative AF to support the development of the EA in the military domain. DoDAF is composed of eight viewpoints and 40 views that are affiliated with the viewpoints. To develop an AF for a specific goal, system architects decide a set of views. Furthermore, they determine data that are needed for a view modeling. However, views and data in DoDAF are structurally inter-related explicitly and/or implicitly. So, developing an AF for a specific goal is going to be a project to be carried out over a long haul. To reduce the burden of its development, in this paper, we develop ONT-SAF (Ontology for DoDAF) that can infer inter-relationships like referential and transitive relationships and the sequences among the views. Furthermore, to promote reusability and consistency of the views and the data within an AF, we adopt the view-data separation strategy. ONT-DAT contains classes like 'viewpoint', 'view', 'data', 'expression method', and 'reference model', and 11 properties including 'hasView.' To prove the effectiveness of ONT-SAF, we perform a case study.

The amount and diversity of information is increasing, as is the information integration connecting data among the related institutions. In the defense field, DTAQ, which is in charge of the quality of military supplies, is attempting to collect and analyze the information which is related with it. In addition, the object of information integration is to expand civil data as well as defense data. There are many ways to integrate data in various environments. In the defense field, which needs enhanced security, it is necessary to establish and apply the information integration methods which are enhanced with more security. In this study, the framework and architecture of information integration was designed by considering task requirements and security conditions. As a result of example application of this framework for information systems to the selected 4 institutions, it was confirmed that the task can be performed through data connections. From the study result, integration architecture which can be applied securely in defense field was suggested. The data accumulated by using this framework with strengthened security are expected to be utilized for the quality improvement of military supplies.

The Korean military has developed and operated computer, network, communication technologies as well as war game models to strengthen the national defense M&S continuously. In particular, lots of projects for developing models for drill/training, analyses, and acquired fields are being conducted in the military. However, it needs to look into the actual conditions and seek for strategies to develop the national defense M&S. First of all, in the field of war games, various national defense architectures have been built, including war and information environment architectures starting from the resource architecture in 2006. However, the function of drill and training is limited, so additional war game architectures are required to be built. To build joint war game architectures available as an effective verification tool to implement plans of the national defense and war architectures, this study examines the actual conditions of the current war game systems and suggested building joint war game architectures.

국방 분야의 시스템 개발은 다양한 데이터표준 및 프로토콜로 인해 체계 간 상호 연동에 어려움이 있다. 특히, 다양한 아키텍처가 적용되는 LVC 연동훈련 체계는 적용 프로토콜 간 데이터 교환을 위해서 공통의 표준기술이 필요하다. 본 논문은 이러한 이기종 체계들 간 상호 연동을 위해서 객체 모델 변환 프레임워크를 제시하였다. 제안 프레임워크는 다양한 이기종 체계가 가지는 객체 모델들과 프로토콜들을 구분하여 독립적으로 연동할 수 있도록 하였다. 또한, 체계 간의 종속성을 줄이고 구성 요소의 유연한 설계를 제공하기 위해서 3-Part 지원 모듈의 플러그인 방식 구조로 설계하였다.

Many Countries are recently focued on building capability based military and operating for the defense budget efficiency and operational effectiveness. The EA not only defines enterprise scope but also identifies relation among them, manage change and complexity. Accordingly, this research aims to build architecture framework which can achieve alignment, integration and interoperability by developing it with output. Through this, architecture framework can be changed into force development and operation. And it can be used for construction of effective force and operation for NCO by applying mathematical model and method of force priority development based on developed capabilities-based architecture framework.

S/W 제품계열(S/W Product Line)은 공통의 유사한 기능을 지닌 S/W 제품 또는 S/W 시스템의 집합을 의미한다. S/W 제품 계열을 통해 특정 영역의 시장과 용도의 요구사항을 만족하여 특정 S/W 제품 개발시 미리 구축된 S/W 아키텍처 등의 S/W 핵심 자산을 재사용하여 개발한다. S/W 제품계열 기반의 S/W 개발방식은 미리 구축된 S/W 핵심자산을 재사용함으로 처음부터 전체 시스템을 개발하는 방식보다 쉽고, 빠르게 S/W를 생산할 수 있다. S/W 기술 선진국들은 S/W 제품계열을 S/W 생산기술의 핵심 분야로 선장하고 중점적으로 기술 개발을 지원하고 있다. 미국의 CMU/SEI는 산업체 및 국방성과 함께 제품계열 프레임워크 4.0 (Product-Line Framework 4.0)을 개발하였고 유럽은 ITEA(IT for European Advancement) 프로그램에서 제품계열 기술 개발을 지원하고 있다. 그러나 국내의 경우 S/W 개발의 생산성 향상 방안으로 제품계열 기반 S/W 생산기술의 필요성을 인식하고 있으나, 기술 개발 투자는 미흡한 상황이다. 본 논문에서는 이러한 S/W 제품계열 생산을 위한 S/W 제품계열의 공통 아키텍처를 정립하는 것을 목표로 하고 있다.
