Currently, the Republic of Korea is facing the problem of a decrease in military service resources due to the demographic cliff, and is pursuing military restructuring and changes in the military force structure in order to respond to this. In this situation, the Army is pushing forward the deployment of a drone-bot combat system that will lead the future battlefield. The battlefield of the future will be changed into an integrated battlefield concept that combines command and control, surveillance and reconnaissance, and precision strike. According to these changes, unmanned combat system, including dronebots, will be widely applied to combat situations that are high risk and difficult for humans to perform in actual combat. In this paper, as one of the countermeasures to these changes, autonomous behavior software with a BDI architecture-based decision-making system was developed. The autonomous behavior software applied a framework structure to improve applicability to multiple models. Its function was verified in a PC-based environment by assuming that the target UAV is a battalion-level surveillance and reconnaissance UAV.

오늘날 기술의 발전으로 시스템들은 점차 대형화 복잡화 되어가고 있다. 이처럼 점차 대형화 복잡화 되어가고 있는 시스템들은 더욱 커진 사고 및 고장에 대한 위험을 내재하게 된다. 또한 대형 복합 시스템에서 발생하는 사고 및 고장은 바로 큰 재산피해나 인명피해와 직결 될 수 있다. 따라서 체계적인 안전관리의 필요성이 점차 커지고 있다. 이에 대응하여 철도, 항공, 해양 등의 산업에서는 각 산업에 적합한 안전관리체계를 수립하려 노력하고 있으며, 표준 및 매뉴얼을 제정하여 보급에 앞장서고 있다. 또한 시스템에서 전장품 및 소프트웨어가 차지하는 비중이 커지면서 기능안전이 안전분야의 이슈가 되고 있다. 이에 따라 IEC 61508, ISO 26262, IEC 61511 등 기능안전관련 표준들이 제정되어 기능안전을 달성하기 위한 기반을 제공하고 있다. 한편 국내 철도산업에서도 철도안전법의 재정을 기점을 철도 산업전반에 걸쳐 많은 환경변화가 이뤄지고 있고 이에 대응하기 위해 철도 안전시스템을 바탕으로 한 안전관리체계를 구축하였다. 한편 다양한 운영체계를 갖고 있는 철도시설 및 운영기관이 존재하는 국가 철도 안전관리체계의 안전규제를 체계화하기 위해서는 체계적인 요구사항의 분석에 따른 시스템 아키텍처의 설정이 요구되고 있다. 이러한 아키텍처의 설정은 현재에 대한 분석과 미래의 철도안전시스템의 특성을 구조화하여 향후 비전을 프레임워크로 표현함으로서 구현이 가능해진다. 본 논문에서는 현재의 안전관리체계의 도입 배경 및 도입 현황에 대해서 분석하고, 최근 기존의 안전관리체계와 더불어 최근에 안전분야에서 이슈가 되고 있는 기능안전 표준을 반영한 안전관리체계의 구축을 위해 안전관리체계에 대한 아키텍처를 구현하고자 하며 이때, 모델링을 바탕으로 한 접근을 제시한다.

Modeling and Simulation techniques are useful to construct executable battlefields and forces on computers, and have been utilized to analyze effectiveness of weapon systems in the computerized war environment. However, most weapon simulations so far have exhibited low reusability and extensibility, since they have been developed for specific simulation objectives with different structures and simulation engines. In this paper, we identify requirements for defense modeling and simulation activities and propose a simulation engine to support the identified requirements. We define the software architecture of the proposed engine, in a way to efficiently provide usability, component-based reusability, interoperability, and reuse-based development.

During the past several years the ROK military has made an effort to build LVC synthetic battlefield that reflects the real world environment. In spite of its efforts, little has been accomplished. The disappointing achievement is mainly due to the lack of operational requirements and concepts, and policies or systematic approaches on the architecture and technology. Furthermore, there is insufficient understanding on the basic concepts and principles, and conflicting interests between organizations. In this study, I propose to construct an LVC based on the HLA that focuses on the system view and technical standard view, rather than the operational view. The proposed approach employs the information centric integration, focuses on an architecture convergence efforts based on the HLA/RTI, emphasizes the HLA compliance test and federation test, adapts to DSEEP, DMAO, and FEAT, and finally invents and implements an LVC Compliance Test System.

Ground troops as part of the implementation of the real-time visualization of battlefield tactics to ensure the exchange of information sharing and situational awareness for the ground tactical data link system development is underway. However, with the existing inorganic KVMFbased weapon systems and tactics Quarterly problem occurs because the information has not been in development or in the development of future weapons systems based KVMF share battlefield information to enable interoperability building measures is presented.

This paper describes a development of the operational architecture of a low altitude air defense automation system using a systems engineering approach. The future battlefield is changing to new system of systems that command and control by the network based BM/C4I. Also, it is composed of various sensors and shooters in an single theater. Future threats may be characterized as unmanned mewing bodies that the strategic effect is great such as UAVs, cruise missiles or tactical ballistic missiles. New threats such as low altitude stealth cruise missiles may also appear. The implementation of a low altitude air defense against these future threats is required to complex and integrated approach based on systems engineering. In this view, this work established an operational scenario and derived operational requirements by identifying mission and future operational environments. It is presented the operational architecture of the low altitude air defense automation system by using the CORE 5.0.

Kill Chain is getting attention due to North Korea's recent nuclear test and missile launches and has emerged the need for an early build up. In order to build a materialized kill chain, you should review the unique kill chain to support operations effectively using various sensors and striking weapon system. Especially, you need a suitable network to reduce a reaction time against the enemy attack under joint operations environment etc. Currently there are many communication ways(e.g. data link, voice, video and text message) used in operations through satellite, wired and wireless and so on. Now, this paper contains analysis on various means for target information exchange which are used in the kill chain. And appropriate network of the kill chain for target information transmission is addressed to confirm feasibility of its alternatives, which is developed using AHP(Analytic Hierarchy Process). Finally, this paper is suggesting network and means of its building up for target information transmission of kill chain which can be implemented under the situation of joint battle field.

This paper focuses on reverse simulation methods to find and analyze the required performance of a defense system under a given combat effectiveness. Our approach is motivated that forward simulation, that traditionally employs the effectiveness analysis of performance alternatives, is not suitable for resolving the above issue because it causes a high computational cost due to repeating simulations of all possible alternatives. To this end, the paper proposes a reverse simulation software architecture, which consists of several functional sub-modules that facilitate two types of reverse simulations according to possibility of inverse model design. The proposed architecture also enable to apply various search algorithms to find required operational capability efficiently. With this architecture, we performed two case studies about underwater and anti-air warfare scenarios. The case studies show that the proposed reverse simulation incurs a smaller computational cost, while finding the same level of performance alternatives compared with traditional forward simulation. Finally we expect that this study provides a guide those who desire to make decisions about new defense systems development.

In this paper, the multi-resolution simulation of standard linkage architecture is consists of the engineering-level (QUEST), engagement-level (SADM), the mission-level (EADSIM). It was developed the engineering-level model using battle experiment integrated development environment in the battle experimental engineering system. The engagement level model was developed using the SADM and the mission-level model was developed using EADSIM. The standard linkage architecture is designed and implemented in order to interlocking model of multiple layers. Each different simulation programs in a distributed environment was designed by HLA interface specifications for satisfying interworking. Also the integrated interoperation gateway was developed for relaying the each different simulation programs. The effective naval weapon system for measure of effectiveness develops using to improve the fidelity of the model between the various layers through multi-resolution interoperation simulation. According to the operator requirement is quickly battlefield environment can be constructed. The other simulation program that being designed through standards linkage architecture can linkage easily and efficiently.
