군 요구분석부터 시험평가까지 전반적인 단계에 활용 가능한 합성 전장 환경을 구성하기 위해 컴포넌트기반 체계모의환경(AddSIM)이 개발되었다. 또한 AddSIM을 효과적으로 활용하기 위해 표준화된 계층구조를 가지는 무기체계 컴포넌트 모델인 기본체계모델(BSM)이 개발되었다. 본 논문에서는 AddSIM에서 운용 가능한 유도 무기체계의 BSM 상세 설계에 관해 기술한다. 유도 무기체계 BSM은 재사용성과 상호 운용성을 고려해 설계되었으며 조립성을 고려해 상이한 해상도의 하위컴포넌트에 대해서도 동일한 인터페이스를 갖도록 설계되었다. 그리고 컴포넌트 해상도 분류 체계에 따라 각 하위 컴포넌트의 해상도 별 컴포넌트를 정의 및 구현했다. 최종적으로 하위 컴포넌트 조합을 통해 다양한 해상도의 유도 무기체계 모델을 구성하였으며 시뮬레이션을 통해 성능을 비교 분석했다.

A study on common modular design based on open standards to reduce the life cycle cost of ground weapon system is underway. Since the ground weapon system includes major mission equipment such as fire control system, it is essential to apply the concept of fault tolerance through automatic reconfiguration and blocking unspecified equipment through connectivity control. However, it is difficult to generalize due to the difference in operating characteristics for each system. In this paper, we propose a plug-and-play framework, which includes plug-and-play architecture and mechanism. The proposed method can be used in common by the application of each component as it is divided into a common service layer. In addition, the proposed connectivity control and autonomous reconfiguration method facilitates reflection of operating characteristics for each system. We constructed a verification environment that can simulate ground weapon systems and components, and verified that the proposed framework works through scenario-based functional tests.

Weapon system is defined as a combination of primary system and logistics support system which are evaluated by capability and operational availability respectively. Weapon system developer thought that primary system was weapon system and also only primary system was important. Recent comparison of total life cycle cost showed that logistics support system was proved to be more important than primary system. However, until now no systematic approach to logistics support system development have applied in the area of developing support system and much money was exhausted by wrong logistics support system. We need to construct a universal metric for effectiveness of logistics support system and to cut out whatever activities or support elements which do not contribute to the metrics. This study describes a new approach under the name function approach to logistics support system development and also classifies five factors of failure frequency, stock out of frequency, administrative delay time, active repair time and logistic delay time that have influence on operational availability of logistics support system.

최근 무기체계가 복잡화, 다기능화 됨에 따라 최종 사용자인 소요군의 무기체계 운용, 정비 난이도가 점점 높아지고 어려워지고 있다. 그러나 이와 반대로 운용, 정비를 수행하는 운용병, 정비병의 근무(복무)기간이 단축되면서 장비 운용, 정비에 대한 숙련도가 낮아지고 있으며. 이러한 장비의 복잡화, 다기능화는 사용자와 정비자의 오작동, 실수 등을 유발시키게 되고 이로 인한 무기체계의 신뢰성 저하는 가용도, 전투준비태세 및 고장수리에 따른 수명주기비용에 영향을 미치고 있다. 이에 따라 소요군에서 운용간 발생한 고장사례 분석을 통하여 시사점을 살펴보고 이를 개선하기 위한 설계측면, 종합군수지원(ILS) 측면의 개선방안을 제시한다. 분석된 무기체계는 현재 해군에서 운용 중인 무기체계로 야전 운용간 실제 발생한 고장사례 730건에 대하여 수집하여 분석하였으며 1차 적으로 고장원인별 분류된 결과를 2차로 사전예방 가능한 고장과 사전예방 불가능한 고장으로 분류하여 사전예방 가능한 고장이 어느 정도 차지하는지 정도와 이에 대한 시사점, 사전예방 가능한 고장별 고장 최소화를 위한 대책과 제안사항을 제시하였다.

In this paper, we have analyzed documentation cases since DAPA establishment, in which documents must be produced as a result of weapon system development corresponding to systems engineering procedures. To develop documentation materials based on systems engineering, instructions of DAPA and US military standards that define development phases, are presented and analyzed in the point of standardizing documents. As a result, we propose a kind of documentation based on systems engineering which is essential for the weapon system development.

The reliability test is a crucial step for ensuring robustness of high-cost and complex weapon systems. In this paper, we present a set of quantitative criteria to select critical parts or components in weapon systems for the reliability test, and implement a fuzzy inference system by applying developed criteria to fuzzy theory. We classify the selection criteria of critical parts or components into four fuzzy sets and membership functions. A fuzzy inference rule is proposed based on the AHP (Analytic Hierarchy Process) analysis technique so as to derive a convincing reliability test. The credibility of the fuzzy inference system is confirmed through a case study using actual equipment data exacted from an existent weapon system.

LOS analysis is used for optimal deployment of mid-range guided weapon system or system engagement effectiveness simulation. Comparing to real-world, LOS analysis includes error sources such as coarse terrain data resolution, refraction of radio waves, and several ideal assumptions. In this research, exact LOS algorithm under assumption of constant earth curvature and error analysis of that is investigated. It proved that LOS algorithm under assumption of constant earth curvature has negligible error in mid-range guidance weapon system's scope.

In next war, it will be expected that some requirement such as information acquisition, battlefield surveillance and control, increased power projection, precision attack by guided missile and electronic warfare may have special importance. The use of robot weapon system by Airforce will make up for some weak points of man based weapon system that Airforce currently has. And Airforce man/robot combined air vehicle weapon system can extend military operational theater and give its flexibility in next war where power, mobility and information should be all-in-one for military purpose.

무기체계 개발 시 종합군수지원 측면에서 중요한 것 중 하나가 동시조달수리부속 산출이다. 동시조달수리부속은 무기체계 가용도 향상 측면에서 매우 중요한 것으로, 이에 대한 다양한 연구가 이루어지고 있다. 그러나 대부분의 연구는 하부 구성품의 고장이 무기체계의 다양한 기능에 미치는 세부 영향들을 고려하지 못하고 있다. 즉 하부 구성품의 고장이 무기체계의 특정 기능에 미치는 영향이 미비하면, 구성품 교환과 같은 정비가 필요 없다는 점을 고려하지 못한다. 그래서 본 연구에서는 고장-기능 간 관계도를 이용하여, 하부 구성품의 고장이 무기체계의 다양한 기능에 미치는 세부 영향을 고려한 동시조달수리부속 산출 방법을 기술하였다. 본 연구 절차는 다음과 같다. 첫째, 무기체계의 운용 및 정비 시스템을 분석한다. 둘째, 고장-기능 간 관계도를 개발한다. 셋째, 수집된 자료를 바탕으로 시뮬레이션 모델을 설계 한다. 마지막으로, 시뮬레이션과 메타 휴리스틱 모형인 진화 전략을 통해 동시조달수리부속 최적 수량을 선정한다. 해당 연구는 동시조달수리부속 산출 연구에 새로운 방향을 제시하였다.

North Korea's science and technology policies are being pursued under strong leadership and control by the central government. In particular, a large part of the research and development of science and technology related to the Fourth Industrial Revolution in North Korea is controlled and absorbed by the defense organizations under the national defense-oriented policy framework, among which North Korea is making national efforts to develop advanced technologies in artificial intelligence and actively utilize them in the military affairs. The future weapon system based on AI will have superior performance and destructive power that is different from modern weapons systems, which is likely to change the paradigm of the future battlefield, so a thorough analysis and prediction of the level of AI militarization technology, the direction of development, and AI-based weapons system in North Korea is needed. In addition, research and development of South Korea's corresponding weapon systems and military science and technology are strongly required as soon as possible. Therefore, in this paper, we will analyze the level of AI technology, the direction of AI militarization, and the AI-based weapons system in North Korea, and discuss the AI military technology and corresponding weapon systems that South Korea military must research and develop to counter the North Korea's. The next study will discuss the analysis of AI militarization technologies not only in North Korea but also in neighboring countries in Northeast Asia such as China and Russia, as well as AI weapon systems by battlefield function, detailed core technologies, and research and development measures.
