This paper presents the overall valuation framework of the Army Tactical Command Information System(ATCIS) with its empirical data which is developed by the ROK Army in 2005 with its own R&D efforts over the past 10 years. The valuation with the appropriate methods is conducted through the full and relentless support of ROK Army HQs, defense agencies, and related firms. And the results include both qualitative and quantitative values of the ATCIS in perspectives of economic, technical, and defense strength effects. As a result, the development of ATCIS is valued over 1.7291 trillion Won which is over 6.55 times benefit and cost ratio comparing with other country's similar system. The worth of this paper includes the actual framework and methods to apply the valuation of other weapon systems and its preliminary research, defense offset valuation, performance evaluation and others.

As the types of North Korea's provocation are diverse and unexpectable in the costal area, ROK navy needs to develop countermeasures, such as costal defence guided rockets. Recently ROK navy developed the PKX-B which is equipped with the new 130 mm guided rocket. The most popular rockets are LOGIR for short range targets, 130 mm guided rocket for middle range targets and Spike-NLOS for long range targets. As various guided rockets are developed, it is required to develop a guided rocket analysis model and it's analysis methodology. In addition, these guided rockets can be installed on any platforms; ground vehicle, aircraft and warship. The paper proposes systematic methodology to estimate the operational effectiveness of costal defence guided rockets. A case study exploiting the ARENA simulation model is explained to demonstrate the implementation of the proposed methodology.

The SBA Integrated Information system is constructed and operated for scientific and systematic management of Defense information utilizing whole process of weapon system acquisition from requirement institution to operation maintenance. In order to utilize m&s resources actively and effectively in the life cycle of weapon system acquisition, efficient management plans of the SBA integrated Information system is required. As a result of identifying usage on SBA Information system and performance of operation performance measurement, it was defined that establishment of the SBA Integrated Information system process and provision of detailed system are mandatory for activating m&s resource and supporting process of acquisitions. In this study, Defense m&s information system is analyzed and improvement plans of SBA Integrated Information system is provided for efficient operation of SBA integrated Information system.

This paper introduces experimental design and components model for analysing the impact of parameter(in the field of kinematics and sensor) on performance of hard-kill torpedo defence system. The simulation is implemented at the level of engagement and its scope is limited to final stage of engagement where main function of anti-torpedo system is operating. It improves the fidelity of physical realism by precise model of simulation components in the perspectives of kinematics, sensor capability and acoustic detection theory. This paper provides the experimentation methodology for evaluating parameter sensitivity which is required to analyze in advance of development the defense system with novel concepts. In addition, the experimental result shows the tendency of defense capability according to parameter adjustments.

This paper introduces the simulation concepts and technical approach of underwater weapon system performance analysis simulator, especially focused on probabilistic target detection concepts. We calculated the signal excess (SE) value using SONAR equation, then derived the probability density function(PDF) for target presence($H_1$) or absence($H_0$) cases, respectively. With the Neyman-Pearson detector criterion, we got the probability of detection($P_D$) while satisfying the given probability of false alarm($P_{FA}$). At every instance of simulation, target detection is decided in the probabilistic perspective. With the proposed detection implementation, we improved the model fidelity so that it could support the tactical decision during the operation.

This study compares the educational effect using real equipment, virtual reality, and video to improve the educational and training effect of the army and verifies which method of education is excellent. The Army has made a lot of efforts to realize the actual training environment, however, it is increasingly difficult to provide the actual training environment because of 1) restrictions on securing training sites and urbanization, 2) deepening conflicts with the people, and 3) difficulties in acquiring defense budget. To resolve these issues, the use of virtual reality(VR) has the advantage to experience actual battlefield indirectly and could save budget by training in a virtual battlefield environment. In particular, in the case of dangerous or expensive weapons systems, is further required. Hence this paper studies how effective virtual reality is compared to the actual weapons system. virtual reality(VR) education is less effective than actual equipment education, but it is higher than video education. Based on this research result, it will be used as a basic data for the analysis of educational effects based in virtual reality(VR).

과거의 전쟁은 재래식 무기에 의존한 화력전이었지만, 미래의 전쟁은 C4I와 전략무기의 중요성이 강조되는 정보전으로 변화될 것으로 예상된다. 현재 활용중인 대부분의 워게임 모형들은 대형전산기 위주로 개발되었으므로, 정보전 개념을 모의하기 위해서는 모형의 논리구조 개선과 영상전시기능 보완이 요구되고 있다. 하지만 기존 워게임 모형 개선은 최신개발 모형과의 상호 호환성 및 재사용성 측면에서 많은 제약이 따르게 된다. 따라서 세계 각국은 국방모의체계(DM&S)의 발전을 위한 자체적인 종합계획을 수립하여 미래전장에서 적용될 첨단무기체계 효과 분석을 위한 모형을 개발하고 있다. 한국국방연구원은 미래전쟁 양상을 신속하게 분석할 수 있으며, PC에서 운용이 가능한 간이분석모형의 개발을 추진하고 있다. 본고에서는 미래전 분석을 위한 간이모형 개발에 적용된 방법론과 운용논리, 모형검증 기법 등을 소개하고 향후 개발모형의 활용방안을 제시하고자 한다.

In this paper, the combat effectiveness of ship guidance rockets to counter the threat of multiple USV(Unmanned Surface Vehicle) was analyzed in three cases. The probability of sinking a number of USVs approaching by distance was compared using various weapon systems and guided rocket systems installed on the naval vessels. As a result of the analysis, it was found that the combat effectiveness of the guided rocket was improved compared to the close defense system of the anti-ship missile installed on the naval vessels.
