NCS(Naval Combat System)는 함정에 설치된 이기종의 센서와 무기를 연동하여 표적탐지, 추적, 위협분석, 교전 및 명중평가에 이르기까지 함정의 전투효과를 극대화시키기 위한 시스템이다. 함정전투체계의 목적을 달성하기 위해서는 승조원들의 함정전투체계에 대한 운용 숙달이 요구된다. 이를 위해서 함정전투체계에서는 모의훈련 기능을 제공하며, 승조원들은 함상에서 체계 운용 숙달 및 팀워크 훈련을 수행한다. 훈련을 통제하는 훈련교관은 높은 수준의 훈련 통제 및 감시가 가능해야 하며 이에 대한 연구가 필요하다. 본 논문은 훈련교관의 훈련상황 가시화를 위한 3차원 전시 방안을 연구한다.

국방부에서는 "국방개혁 2.0"의 과학화 훈련체계 확대에 따라 가상현실·증강현실 기반의 실감형 전투 모의 훈련체계를 구축하기로 하였다. 실감형 전투 모의 훈련체계는 훈련자간 교전을 통해 실전과 같은 긴장감 조성과 훈련효과를 극대화 할 수 있어야 한다. 또한, 엄폐훈련을 통해 실전과 유사한 사격훈련과 동시에 생존훈련 효과 배가가 가능해야 한다. 선행 연구들은 훈련자의 사격 정밀도를 향상 시키기에는 적합한 기술이지만 실전과 같이 쌍방 교전을 연습하기는 어려우며 특히 엄폐물을 활용한 전투사격 훈련을 하기에는 부족한 점이 있다. 따라서 본 논문에서는 가상 사격 훈련자의 스크린에 상대 훈련자의 사격 자세를 인식하여 가상의 아바타를 생성하기 위해 Depth센서를 통해 취득된 깊이 정보를 토대로 훈련자와 엄폐물을 인지하고 훈련자의 자세를 추정할 수 있는 S/W 알고리즘을 제시한다.

M&S (Modeling & Simulation) based design is widely accepted for the development of the future weapon system with better performance in a cheaper and faster way. Integrated simulation environment (ISE) is needed for the M&S based design. On the ISE, system engineers can not only verify design options but also validate system requirements. In this paper, we propose architectural models of the integrated simulation environment (ISE) which incorporates mission effectiveness M&S (Modeling & Simulation), system performance M&S, the optimization model of integrated performances, digital mockup and virtual prototype. The ISE architectural models may be used to implement the ISE for the development of the future unmanned ground combat vehicle.

The conventional systems engineering has been performed mainly based on documentation artifacts. Although the Document-Based Systems Engineering has played a very important role in developing and deploying systems, it is difficult for systems engineers to build, to clarify, and to reuse the operational, functional and physical views of the System of Interest (SOI) efficiently. An information-age approach to this problem is the Model-Based Systems Engineering which has been emerging as a very productive solution for stakeholders to define, and understand the desired systems easily, to communicate and collaborate efficiently among each other, and also to verify and validate the systems solutions effectively. This paper proposes a set of MBSE process, methods, and models for use during the systems analysis and design phase of the naval combat system development. An example application of the proposed approach was exercised and a set of artifacts was generated for an export combat system project to demonstrate its effectiveness.

Korea Ministry of National Defense has directed the state-of-the-art technology Forces troops structures that can respond to security threats in all directions through the Defense Innovation 2.0, which aims to reorganize the personnel and organizations in response to population decline. An implement of effective analysis to maintain combat power is necessary due to possible restrictions on combat power, especially in division of mobilization where reserve manpower is operated frequently. In this study, the normal operations of the reserve officers were investigated, the direct effects of the combat forces of the reserve officers was analyzed using ARENA modeling, and the budget required to operate the innovation and indirect effects of employment of veterans were studied. The result of the simulation proved to be effective in demonstrating unit combat power when the reserve officer was in full-time operations and economic benefits were also significant in terms of efficiency of defense budget management.

In modern warfare, securing time for preemptive response is recognized as an important factor of victory. The naval combat system, the core of naval forces, also strives to increase the effectiveness of engagement by improving its real-time information processing capabilities. As part of that, it is considered to use the TPR-tree in the naval combat system's target indexing because spatio-temporal searches can be performed quickly even as the number of target information increases. However, because the TPR-tree is slow to process updates, there is a limitation to handling frequent updates. In this paper, we present a method for improving the update performance of TPR-tree by applying the bottom-up update scheme, previously proposed for R-tree, to the TPR-tree. In particular, we analyze the causes of overlaps occurring when applying the bottom-up updates and propose ways to limit the MBR expansion to solve it. Our experimental results show that the proposed technique improves the update performance of TPR-tree from 3.5 times to 12 times while maintaining search performance.

U.S. Air Force Regulation 80-1 defines that a weapon system is composed of equipments, skills, and techniques, the composite of which ferns an instrument of combat. The complete weapon system includes all related facilities, equipments, materials, services, and personnels required for the operation of the system, so that the instrument of combat can be considered as a self-sufficient unit of striking power in its intended operational environment. Effectiveness of a weapon system can be expressed as a function of its liability, reliability and performance capability. Among these attributes which influence the weapon effectiveness, performance capability is considered to be the most critical factor for many weapon systems. In order to illustrate the application of the methodology of performance capability, a specific ease study on the effectiveness of Vulcan anti-air craft gun system is presented with special emphasis on hitting probability on moving targets, effects of artificial rounds dispersion, and several principles related to the deployment of the system. This thesis includes the thorough survey of the possibility of calculating the absolute value of hitting probability on moving targets, indicates that the effects of artificial rounds dispersion increase the value of probability only when the total number of rounds fired within fire range exceeds a certain critical number, and suggests that concentrated guns deployment is better than scattered deployment in order to obtain higher probability and lower average amount of rounds if it is assumed that the effects of counter-attack from enemy threats are not serious.

In this paper, the result of study on the effectiveness of anti-submarine defense plan according to the disposition of surface ships has been proposed. The surface ship carries a hull mounted sonar(HMS) as a underwater sensor and a torpedo acoustic counter measure(TACM) as a soft-kill weapon against torpedo attacks from the enemy. Nowadays these underwater systems have been combined into a integrated anti-submarine warfare combat system. And in the real anti-submarine operation environment, several surface ships cooperate for executing ASW plans. Considering these ASW systems and the ASW environment, the models of underwater systems mounted on an surface ship and the a general model of anti-submarine defense plan are proposed. And we designed a scenario for conducting simulations to evaluate the ASW plan according to the variation of the range and the relative angle between surface ships and a capital ship. The simulation results show the effectiveness of ASW plan depends on the formation of surface ships and a capital ship.

함정 전투체계는 생존성과 임무효과의 극대화를 위해 수집된 정보를 종합하고, 실시간으로 처리하여 최적의 전투능력을 제공하도록 고안되었다. 전투체계의 소프트웨어 컴포넌트는 함정 규모에 따라 수십 개에서 수천 개에 이르며, 각 컴포넌트 간 통신은 메시지 지향 미들웨어인 DDS(Data Distribution Service)를 통해 이뤄진다. DDS를 통한 전투체계 메시지 인터페이스는 MDMS(Message Define & Management System)를 통해 관리되어 왔으나, 체계 규모가 증가함에 따라 개발 효율이 저하되는 등 다양한 문제점들이 대두되었다. 따라서, 본 논문에서는 분산 처리 환경 운용이 가능한 차세대 메시지 정의 및 관리 시스템을 개발하고, 이를 통해 기존의 문제들을 해결하고자 한다. 실험 결과는 XMDMS(neXt Message Define & Management System)가 기존 시스템에 비해 처리 지연 및 네트워크 성능이 향상됨을 보여준다.
