본 논문은 온톨로지 기반의 임무공간 개념 모델링 체계인 한국형 임무공간 개념모델 (CMMSK:The Conceptual Models of the Mission Space-Korea)을 제안한다. 모델링과 시뮬레이션을 이용하면 실제 군사 훈련을 실행할 때 발생하는 시간, 공간 그리고 경제적인 비용을 크게 줄일 수 있다. CMMS-K는 국방 모델과 시뮬레이션의 상호운용성과 재사용성을 향상시키기 위해 개발되고 있다. CMMS-K의 구조는 한국 국방 환경을 기반으로 기존 국방 개념 모델링 체계를 참조하여 생성되었다. CMMS-K의 주요 구성요소는 도메인 온톨로지, 임무공간 모델 기술 언어, 임무공간 모델링 도구, 그리고 CMMS-K 관리 시스템이다. CMMS-K 도메인 온톨로지는 개체 및 과제 온톨로지로 구성된다. 본 논문은 CMMS-K 도메인 온톨로지에 대해서 자세히 기술하고 제안된 방법의 적용 가능성을 예제를 이용하여 평가한다.

The paper describes the analysis of deployment strategies and trajectories design suitable for executing the inspection of an operative spacecraft in orbit through re-usable CubeSats. Similar missions have been though indeed, and one mission recently flew from the International Space Station. However, it is important to underline that the inspection of an operative spacecraft in orbit features some peculiar characteristics which have not been demonstrated by any mission flown to date. The most critical aspects of the CubeSat inspection mission stem from safety issues and technology availability in the following areas: trajectory design and motion control of the inspector relative to the target, communications architecture, deployment and retrieval of the inspector, and observation needs. The objectives of the present study are 1) the identification of requirements applicable to the deployment of a nanosatellite from the mother-craft, which is also the subject of the inspection, and 2) the identification of solutions for the trajectories to be flown along the mission phases. The mission for the in-situ observation of Space Rider is proposed as reference case, but the conclusions are applicable to other targets such as the ISS, and they might also be useful for missions targeted at debris inspection.

ROK Joint Chiefs of Staff in developing an WMA-EA(Warfighting Mission Area-Enterprise Architecture) tries to create the practical buildup requirements of military power through precise requirements and operational capabilities based on the architectures. However, it is difficult to verify the effectiveness of target architectures and do efficient requirement planning because we cannot know the gap of quantitative combat effectiveness between current and target WMA-EAs. This study presents an evaluation method of combat effectiveness and focuses on combat's positive effects in WMA-EAs. The method proposed is based on C2 model which is appropriate for the evaluation of combat effectiveness in architectures. We verify the effectiveness of the proposed method through a case study of an anti-ship warfare architecture.

As CAS, X-ATK, and INT models considered as the most typical Air-to-Ground operation models in ROKAF are mainly designed as the voice-centered system between aircraft and ground control facilities, it is critical to newly develop the Link-16 based model for the ROK-US combined operation between F-15K, AWACS, M-SAM, and KDX-III equipped with Link-16. Former studies had been limited to the CAS operation, and they had mainly focused on reducing the voice transmission time to exchange the information between each mission step with maintaining existing operation steps. Therefore, this paper makes up the weak point in former studies, thereby designing new Air-to-Ground operation model for CAS, X-ATK, INT mission using Enterprise Architecture OV6c, which enables both aircraft and ground control facilities or between aircraft to obtain the real-time information on the location, identification, armament and the real-time image data through the broadcasting function. Based on the analysis of new operation model, we come to a conclusion that by simultaneously exchanging the information on mission between nodes concerned through the broadcasting function of Link-16. It is possible to cut down superfluous steps among the mission steps, and to reduce the mission time. It is clear that it gives rise to improve the battle efficiency and the decision-making tempo as well as the battlefield situational awareness.

A network QoS model for the joint integrated C4I structure was proposed for the integration of network infrastructure and network operations(NetOps) for NCOE. Detailed QoS requirements process of the joint integrated C4I systems are needs in the Multi-Domain Operation Environment(MDOE). A process is proposed for identifying QoS requirements and establishing in the MDOE using JMT(Joint Mission Thread) reference architecture and solution architecture. Mission analysis identify JCOAs(Joint Critical Operational Activities) and related activities based on JMT & System architecture's OVs, and Information analysis identify QoS attributes using System architecture's SVs. Identifying QoS attributes will be registered at PPS Registry by pre-regulated process, and will be set-up by NetOps. MDOE QoS requirement Process will support efficiently MUM-T and smart defense platform users under the future uncertain battlefield circumstances.

우리나라는 보안산업 현장에 적용할 적합한 비즈모델 분석 방법론을 발견하기 어렵고 단편적 이론은 존재하지만 종합적 분석 방법론은 희소한 실정이다. 정보보안 기업 비즈모델 분석은 외부요인과 내부요인에 관해 수집된 정보를 통합하고 포괄적으로 분석하는 정보시스템 개발이 요구된다. 비즈모델 분석을 위한 정보시스템의 소프트웨어 아키텍처는 시스템 설계의 초기 결정사항으로서 초기 결정은 설계, 개발, 테스트, 유지보수에 지속적인 영향을 미친다. 정보보안 비즈모델 분석시 BMO에 기반한 소프트웨어 아키텍쳐는 정보시스템의 목적이나 사명 수행을 지원 한다. 정보보안 비즈모델 분석을 위한 정보시스템은 여러 이해관계자들이 사명과 환경을 결정하며 그 결과가 아키텍처 기술서로 문서화 되어야 활용될 수 있다. 아키텍처 기술서는 소프트웨어 아키텍처를 결정한 근거를 제시하기 때문이다.

Euclid is an astronomy and astrophysics space mission of the European Space Agency. The mission aims to understand why the expansion of the Universe is accelerating and what is the nature of the source responsible for this acceleration which physicists refer to as dark energy. This paper provides both an overview of the spacecraft mechanical architecture and a synthesis of the process applied to establish adequate mechanical loads for design and testing. Basic methodologies and procedures, logics and criteria which have been used with the target to meet a compliant, "optimised" design are illustrated. The strategy implemented to limit the risk for overdesign and over-testing without jeopardizing the design margins is also addressed.

High Level Architecture/Run-Time Infrastructure (HLA/RTI) is used to connect individual simulators on networks in order to interoperate heterogeneous simulators. In defense domain, Ship Air Defense Model (SADM) and Extended Air Defense Simulation (EADSIM) are two of most advanced simulation tools. To interoperate these SADM and EADSIM, this paper attempts to use HLA/RTI that helps to support a Composite Combat Mission Planning Simulation Environment (CCMPSE). The CCMPSE allows us to analyze a group of simulations for comprehensive and accurate experiments. For the first time, this paper analyzes guided missile simulations in EADSIM and SADM by comparing related simulation models in their parameters and considerations. It presents characteristics of these models in view of guided missile simulation perspectives. For the contributions of this paper, it provides insights to select guided missiles between SADM and EADSIM on the CCMPSE according to specific simulation purposes.
