An environmental factor is very important in a war game model supporting military training. Most war game models in Korean armed forces apply the same weather conditions to all operation areas. As a result, it fails to derive a high-fidelity simulation result. For this reason this study attempts to develop factor techniques for a high-fidelity war game that can apply distributed synthetic atmospheric environment modeling data to a military simulation. The major developed factor technology of this study applies regional distributed precipitation data to the 2D-GIS based Simplified Detection Probability Model(SDPM) that was developed for this study. By doing this, this study shows that diversely distributed local weather conditions can be applied to a military simulation depending on the model resolution from theater level to engineering level, on the use from training model to analytical model, and on the description level from corps level to battalion level.

After the bombing of the Cheonan Vessel 2 years ago, military conflicts such as a missile launch became a serious issue. In fact, since especially military training has physical limitations, a research for military simulation education using CBT is needed. Using CBT in military-specialized schools, this paper looks into and analyzes the effects after teaching the functions for repairing artilleries and rifles through online simulation. In addition, the learning effects between the learning group using CBT for training artillery engineers and non-CBT learning group are analyzed.

이산사건 시뮬레이션 기법이 최근 들어 통신망, 각종 제조시스템 등 다양한 분야에 응용되고 있으며 군사용 시뮬레이터 개발을 위한 방법론으로도 활용이 증가하고 있다. 그러나, 군사용 전략 시뮬레이터는 모델간 대규모 상호 작용을 요구하는 속성을 가지고 있으므로 모델간의 사건 전달 방법을 적용한 시뮬레이터를 구현하는 경우에 시뮬레이션을 위한 계산량이 과도하게 요구되어 대규모의 시나리오를 시뮬레이션하는데 어려움이 있다. 본 논문에서는 이산사건 시뮬레이션을 위한 이론적 기반을 모두 갖춘 DEVS 형식론을 개선하여 군사용 전략 시뮬레이터를 개발하기 위한 Framework을 소개한다. 개발되는 시뮬레이션 환경을 DEVS 의미론에 기반한 모델링 환경을 제공하지만 시뮬레이션 속도 개선을 위해 여러가지 방법들을 고려한다. 또한, GIS 기반의 시뮬레이션 애니메이션을 위한 모델 관리 방법 및 데이터 전송 방법을 기술한다.

Military wargame simulation models must support the HLA in order to facilitate interoperability with other simulations, and using parallel simulation engines offer efficiency in reducing system overhead generated by propelling interoperability. However, legacy military simulation model engines process events using sequential event-driven method. This is due to problems generated by parallel processing such as synchronous reference to global data domains. Additionally. using legacy simulation platforms result in insufficient utilization of multiple CPUs even if a multiple CPU system is under use. Therefore, in this paper, we propose conversing the simulation engine to an object model-based parallel simulation engine to ensure military wargame model's improved system processing capability, synchronous reference to global data domains, external simulation time processing, and the sequence of parallel-processed events during a crash recovery. The converted parallel simulation engine is designed and implemented to enable parallel execution on a multiple CPU system (SMP).

부대기동 및 실사격을 적용한 군사훈련이 가장 사실적이며 현실감이 있지만, 부대기동에 따른 교통체증 유발과 실사격 훈련에 대한 민원 증가로 인하여 실기동에 의한 군사훈련을 실시하기에는 많은 어려움이 있다. 그러므로 실사격 훈련의 제한 및 통제형 선형훈련으로 인하여 현장감이 저하되고 학습효과가 상대적으로 떨어지게 되는 단점을 극복하기 위하여, 미국, 영국, 독일, 프랑스 등 군사선진국들은 실전적 훈련묘사 및 정밀 훈련분석이 가능한 과학화 전투훈련장을 구축하여 군사훈련의 성과를 높이고 있다. 국내에서도 육군 과학화 전투훈련장(KCTC) 구축사업이 현재 진행중에 있다. 과학화 전투훈련은 일반적으로 마일즈 장비와 시뮬레이션을 사용하여, 지휘/통제/통신 및 기동, 전투근무 지원에 이르는 군사훈련 전과정을 모의하며, 직/곡사화기 교전, 화학 및 지뢰지대 운용, 항공지원 등 전투과정을 재현함으로써 훈련에 참여하는 지휘관과 병사로 하여금 현장감 있는 전투훈련을 유도한다. 이러한 과학화 전투훈련이 실제 훈련과 동일한 훈련효과를 창출하기 위해서는, 신뢰성 있는 교전 피해평가가 필요하다. 예를 들어, 곡사화기에 의한 살상범위, 피해정도 등이 실무부대 전투결과들과 큰 차이가 발생하면 소기의 훈련목적을 달성할 수 없다. 본 고는 과학화 전투훈련장의 전투피해평가 자료체계에 대한 객관적이고 신뢰성 있는 자료검증방법을 제시하여, 향후 과학화 전투훈련의 신뢰성 제고에 기여하고자 한다.

This study is a study on the interlocking method between emergency preparedness simulation model and military exercise war game model. The national emergency preparedness government exercises are being carried out by a message exercise and technology development for simulation models is being carried out to create a situation similar to the actual practice. In order to create a situation similar to the actual war, the military situation must be reflected and to do so, a link with the military exercise war game model is needed. The military exercise war game model applies HLA/RTI, which is a standardized interlocking method for various models such as Taegeuk JOS, and it is necessary to apply HLA/RTI linkage method to link with these military exercise war game models. In addition, since the emergency preparedness simulation model requires limited information such as enemy location and enemy attack situation on major facilities in the military exercise model, a method of interlocking that can select and link information is required. Therefore, in this study, the interlocking interface design plan is presented in order to selectively link the interlocking method and information between the emergency preparedness simulation model and the military exercise war game model. The main functions of interlocking interface include federation synchronization, storage and recovery, object management service, time management, and data filtering functions.

War simulation system is a virtual space that my tactical simulation exercise is held. The data used in this system are considered sensitive and needs to be protected. But suity vulnerabilities and possible security loopholes were not considered when designing the war game simulation system. So currently the systemis highly vulnerable against hackers and data leakages. This paper proposed a security system for war game simulation system based on considering the currently vulunerabilities and possible suity leakages. The proposed security system supports security patches. In this paper, we analyze vulunerabilities of the running environment of current system and we design and implement the security system that is consisted of three components : Authentication System, Encryption System and Network Security System. The security patches are safe and there are no negative effects on the system's performance. The patches are proved to be effective and very reliable towards solving the security vulnerabilities.

This paper describes the method to solve the optimization problems for stochastic simulation which is represented by military simulations. For this reason, the test fitness function reflecting the characteristics of military simulations, complex and stochastic results, is defined and PSO is used to solve the test fitness function. To control the known weak point of PSO for stochastic simulations, this paper proposes a technique which reevaluates the value of global optimum. By using the technique, the result shows notable improvements. From the simulation results, interactions among the calculation conditions which affect the accuracy and speed of optimization are analyzed. And the strategy for the optimization of stochastic simulations is proposed.

Modeling and Simulation(M&S) technology gets an attention from various parts such as industry and military. Especially, military uses the technology to cope with a different situation from the one in the Cold War and maximize the effect of training against the cost in the new environment. In order for the training based on M&S technology to be effective, the situations of a battlefield and a combat must be more realistically simulated. For this, a technique development on Computer-Generated Forces(CGF) which represents a unit's simulation logic and a human's simulated behaviors is focused. The CGF simulating a human's behaviors can be used in representing an enemy force, experimenting behaviors in a future war, and developing a new combat idea. This paper describes a methodology to accomplish Computer-Generated Forces' autonomous intelligence. It explains the process of applying a task behavior list based on the METT+T element onto CGFs. On the other hand, in the domain knowledge of military field manual, fuzzy facts such as "fast" and "sufficient" whose real values should be decided by domain experts can be easily found. In order to efficiently implement military simulation logics involved with such subjectivity, using a fuzzy inference methodology can be effective. In this study, a fuzzy inference methodology is also applied.
