전투공간 시뮬레이션 결과를 가시화할 뿐 아니라 시나리오 가시화 중에 사용자가 선택한 엔티티의 상세한 관찰을 제공하기 위해 스테레오 3D 모델 뷰어를 개발하여 가시화 시스템의 프로토타입을 구성하였다. 전투공간 가시화를 위해서는 가시화 스프트웨어인 SIMDIS를 사용하였다. 사용자는 시뮬레이션 가시화 스크린 상에서 엔티티를 선택할 수 있으며, 이 엔티티의 자세한 관찰은 스테레오 3D 모델 뷰어에 가시화 된다. 모델 뷰어는 사용자에게 엔티티 관찰 시 몰입감과 인지도를 향상시키기 위하여 헤드 트래킹 기술을 적용하였다. 사용자의 위치를 추적하기 위해서는 깊이 카메라를 이용하였으며, 획득한 깊이 영상을 통해 실시간 사용자 헤드 트래킹을 적용하였다. 구현된 시스템은 SIMDIS를 이용한 전투공간 시뮬레이션 가시화와 스테레오 3D 뷰어를 각각 가시화하기 위하여 2D 디스플레이와 3D TV를 사용하였다.

We suggest the C2 modeling method to develop a simulation model for training command groups which consist of commanders and staffs. By using C2 models in constructive simulation models, combat entities or units directly receive and execute orders from a command group without mediating human role players. We also compare combat results from suggested modeling method with the results of existing models by building and implementing a simulation model with C2 models. Our analysis by comparison demonstrates advantages of suggested method to model C2 for computer assisted exercises.

This paper presents the battle space model, which is capable of propagating various types of emissions from platforms in underwater warfare simulation, predicting interesting encounters between pairs of platforms, and managing environmental information. The battle space model has four components: the logger, spatial encounter predictor (SEP), propagator, and geographic information system (GIS) models. The logger model stores brief data on all the platforms in the simulation, and the GIS model stores and updates environmental factors such as temperature and current speed. The SEP model infers an encounter among the platforms in the simulation, and progresses the simulation to the time when this encounter will happen. The propagator model receives various emissions from platforms and propagates these to other "within-range" platforms by considering the propagation losses and delays. The battle space model is based on the discrete event system specification (DEVS) and the discrete time system specification (DTSS) formalisms. To verify the battle space model, simple underwater warfare between a battleship and a submarine was simulated. The simulation results with the model were the same as the simulation results without the model.

A wheeled armored vehicle is a military vehicle that has been developed to enhance combat capabilities and mobility for the army. The wheeled armored vehicle has a high center of gravity, and it operates on unpaved and sloped roads. Therefore, this vehicle has a high risk of rollover crashes. To design the interior of the military vehicle, the crew's safety during rollover crashes is an important factor. However, actual vehicle tests for design are extremely expensive. In this paper, nonlinear dynamic analysis is performed to simulate the rollover crashes and the passenger injury is assessed for a wheeled armored vehicle. The scope of this research is the rollover condition, FE modeling of the wheeled armored vehicle and the dummy, arrangement of dummies, assessment of passenger injuries, and simulation model for rollover crashes.

The purpose of this paper is to propose a methodology that can measure the combat effectiveness of attack helicopter which Korea army will be operating in the near future. To measure the combat effectiveness, firstly, we use a wargame model, AAsim (Army Aviation simulation), as a analytic simulation model which is used to analyze DOTMLPF and operation in army aviation field, secondly we use an Analytic Hierarchy Process by opinion of experts. For simulation and AHP, we consider anti armored corps operation reflecting attack helicopter's combat effectiveness. As a result of this study, the combat effectiveness per each attack helicopter can be measured and this combat effectiveness is useful for reasonable decision making such as selection helicopter type, quantity when acquiring new weapon system.

Anti-Air Warfare(AAW) functionality of the naval combat system is the key functionality to ensure the ship's survivability. We have applied a novel method using model-based-simulation to analyze and design AAW functionality of the Patrol Killer Experimemnt Combat System. In this approach, an AAW functional model is described with the FSM(Finite State Machine) and directly executed for the AAW simulation. After prototyping using model based simulation, Hardware In Loop Simulation(HILS) is conducted as the AAW functionality is interfaced with the other ones of the combat system for completing the integration of the system components. This incremental and iterative development approach based on the model based simulation can minimize the development risks and costs caused by the system complexity for military system, bringing out the merit of the rapid prototyping.

The real data obtained from field exercises has a crucial role in modeling and simulation of a combat or a wargame. This becomes an important input especially in analyzing weapon systems realization. Many existing models have been using the mean value of the time between each fire. The firing data can be incorporated into a known probability distribution or used directly as an empirical distribution. Data of field exercises are very useful instead of the real combat outcomes. This study finds a new modeling approach and techniques to compare the data with the previously generated outcomes. This fundamental research work will continue to consider more of the various weapon systems, the sizes, and other tactical aspects.

Most battleship warfare M&S systems run relatively slow and the simulation results are often unfair since the system should interact with human operators(controller and/or gamer). To deal with these problems, we have proposed the agent-based battleship warfare M&S system which interact with multiple agent systems instead of human operators. Agent-based M&S system may be able to efficiently support the analysis of effectiveness and/or the operational tactics development of given warfare by providing autonomous reasoning capabilities without the intervention of human controller. To do this, the paper propose the design concept and methodology using the advanced modeling and simulation framework as well as autonomous agent design principle. Several simulation tests performed on the battleship warfare case study on Korea Yellow sea will illustrate our techniques.

최근 산업체, 공공기관 등 거의 모든 분야에서 인터넷 기술을 이용한 클라이언트/서버환경으로 시스템을 구축하고 있다. 본 논문에서는 이러한 환경에서 DIS와 ADS의 개념을 이용한 전투 시뮬레이션을 수행하여 기존 모델의 비현실적인 가정과 문제의 난이도로 인한 여러 제약을 해결할 수 있으며 시간 및 시스템의 활용면에서 효율의 증가에 대한 모델을 구현하였다. 본 전투 시뮬레이션 모델은 인터넷 프로토콜의 표준으로 자리하고 있는 TCP/IP를 이용한 것이기 때문에 이동통신을 이용한 무선 데이터는 물론, 인터넷 접속이 가능한 곳이라면 어떠한 환경에서도 수행이 가능하다. 노드에서 시뮬레이션이 종료되면 여기서 발생한 생존 대수, 발사시간 분포 등의 정보는 서버에서 적절한 의사결정을 수행한 후 다른 노드로 전달하게 된다.
