네트워크중심전(NCW) 구현을 위한 상호운용성의 중요성이 날로 증대되고 있는 시점에서 전투원에게 보다 빨리, 보다 저렴하게, 보다 우수한 무기체계를 제공하고자 하는 국방획득환경의 변화로 인해 국방 모델링 및 시뮬레이션을 활용한 SBA에 대한 관심이 고조되고 있다. 그러나 현재의 국방 모델링 및 시뮬레이션 모델은 유무선 네트워크 통신 효과를 적절히 반영하거나 고려하지 못하고 있기 때문에 다양한 네트워크 영향 평가 자체를 할수 없다. 그런 관점에서 우리군이 무기체계 특히 통신시스템을 획득함에서 있어 네트워크중심전(NCW) 구현을 위한 수단으로서의 네트워크중심 국방 모델링 및 시뮬레이션(이하 Network -Centric DM&S)을 활용하여 SBA를 적용하는 방안을 도출하고자 한다. 이에 한국군 국방 모델링 및 시뮬레이션에서 Network-Centric DM&S의 개념과 필요성을 언급하고, 통신시스템과 갈은 무기체계획득분야에서 Network-Centric DM&S를 활용한 SBA 적용 방안과 그 적용사례를 고찰하고자 한다.

The Test and Evaluation (T&E) system became more important due to its advancement and complexity of the weapon system. Time and cost saving T&E related studies are in progress mainly with advanced countries. By utilizing the Modeling and Simulation (M&S) technology recently, we may save time and money. Also, overcome security and safety limitations. There are many M&S based research activities in South Korea but it is way behind of the system that some countries already have developed. i.e.; United States. This area of study requires new way of developing strategies in the T&E system of Korea. This study is to design the Operational T&E system for weapon systems based on modeling of processes. And we modeled the processes of operational performance evaluation through utilizing resources and performance modules of weapon systems and combined it with the simulation engine for 3D visualization. Through this, we propose the Operational T&E system for weapon systems based on modeling of processes that represent operational performances visually.

As a new paradigm called modeling and simulation(M&S) or simulation based acquisition(SBA) has arisen, necessity of applying it to Korea has been increased. Not only rational construction of SBA but development of model which can evaluate driving results and improve relating processes to SBA is needed. Therefore we suggests the framework of capability maturity model for M&S development and SBA. The ultimate purpose of our model is improving processes relating to M&S development and SBA. The last section include detailed model which has practices for improving some SBA processes.

최근 모델링 및 시뮬레이션 분야에서는 HLA에서 정의하듯이, 여러 가지 시뮬레이션이 동일한 환경에 참여하여 동시에 상호작용 하는 분산 시뮬레이션을 추구하고 있다. 따라서, 이미 모델링 되어 있는 데이터를 재사용하고 확장할 수 있는 방법이 중요해지고 있다. 미국 국방부에서는 이러한 목적으로 합성 환경의 표현과 교환을 위해 SEDRIS와 같은 표준 개념들을 만들고 있으며, 산업계에서의 모델링 및 시뮬레이션 영역에서도 역시, 호환성과 원가절감의 측면에서 표준의 개념을 도입하기 위한 노력이 진행되고 있다. 본 연구에서는, 상업용 디지털 생산 시뮬레이션 솔루션인 DELMIA에서 사용하는 데이터와, 합성 환경의 표준인 SEDRIS 데이터간의 매핑 방법을 설계하고 구현하였다. 이를 통해, 환경 데이터의 표준 기술인 SEDRIS를 DELMIA와 같은 상업용 디지털 생산 시뮬레이션 데이터를 표현하고 교환하는 표준으로서 활용의 가능성을 검토하였다.

An integrated simulation engine provides tools, services, and standards to support various activities in the entire M&S from modeling and simulation to analysis of the simulation results. Many countries have developed integrated simulation engines to efficiently assist complex M&S activities. However, we do not have domestic simulation engines especially designed for defense M&S, therefore, developing M&S softwares still remains as a hard task with high cost and tine. OpenSIM(Open Simulation engine for Interoperable Models) is an integrated simulation engine and provides tools, services and standard interfaces for weapons analysis. OpenSIM's services are comprised of classes, member functions and data attributes which are commonly used in modeling, simulating and analyzing weapons systems. In this paper, we introduce OpenSIM's services in C++ APIs and illustrate them through an ASM example(Air to Surface Missile).

In applying modeling and simulation (M&S) techniques to analyze complex discrete event dynamic systems, conventionally users had to use different simulation environments depending on the user-level. To solve the inconvenience, this paper proposes an integrated development environment for M&S depending on user-level and a formalized interface to manage the model in the development environment efficiently. The interface consists of an extended DEVS formalism and model making rules. The development environment is divided into a modeling environment and a simulation environment. In the modeling environment, three modeling methods are provided for each level of the users. Users inputs several parameters to the model generated as a result of the modeling process, and experiments in various cases by using the simulation environment. The case study shows the implementation of the proposed M&S environment, and using the implemented environment, it shows the M&S process of the complex defense combat system.
