The naval combat system is a distributed system in which various subsystems are integrated and operated together. The integrated management system(IMS) is a software system for systematically and consistently managing the application software which control and operate various devices in such a combat system. Since the malfunction or failure of such an IMS can disable the entire combat system, the IMS is more important than other application software of the combat system. In this paper, we propose a method to guarantee the stable and correct operation of the combat system. To this end, we propose a redundancy scheme composed of one leader and several followers so as to tolerate the failure situation of the IMS. We also propose a leader selection algorithm to select a new leader when the leader fails and can no longer perform its role. To verify the validity of the study, we verify the fault tolerance behavior of the system and the accuracy of the leader selection algorithm.

본 논문에서는 보안성과 안정성을 유지하면서 함정 전투관리체계의 생존성을 향상시키는 체계 접근통제 소프트웨어를 제안한다. 함정 전투관리체계를 구성하는 체계접근통제 소프트웨어의 운용 환경 구성 및 사용자 인증 프로세스 개선, 함정 전투관리체계 운용 환경 분류 정의, 부하율을 고려한 소프트웨어 병렬 실행 프로세스를 적용하여 체계접근통제 소프트웨어를 개선하였다. 이를 통해, 환경 구성에 필요한 대기시간을 단축하여 운용자에게 신속한 운용을 제공하고, 긴급한 상황 속에서도 환경 구성이 완료되지 않으면 함정 전투관리체계를 운용할 수 없는 점을 개선하고자 한다. 그리고 성능을 시험하기 위해 기존 함정전투관리체계를 모의하여 시험환경을 구성하였으며, 운용 분류 별 실행시간을 측정하여 비교하였다. 기존 함정 전투관리체계 대비 기본 전투관리체계 실행시간은 약 69.3% 감소하였으며, 교전 전투관리체계 실행시간은 약 54.9% 감소하였으며, 통합 전투관리체계 실행시간은 약 8.4% 감소하였음을 확인하였다. In this paper, we propose system access control software that improves the survivability of the naval combat system while maintaining security and stability. The software was improved by improving the operating environment configuration and user authentication process of the system access control software that constitutes the naval combat system, defining the operating environment classification of the naval combat system, and applying a software parallel execution process considering the load rate. Through this, the waiting time required to configure the environment is shortened, providing rapid operation to the operator, and improving the fact that the naval combat system cannot be operated unless the environment configuration is completed even in emergency situations. In order to test the performance, a test environment was created by simulating the existing naval combat system, and the execution time for each operation category was measured and compared. Compared to the existing naval combat system, the execution time of the basic combat system was reduced by about 69.3%, the execution time of the combat system was reduced by about 54.9%, and the execution time of the integrated combat system was confirmed to be reduced by about 8.4%.

장재욱 국방보안연구소 2021 국방과 보안 Vol.3 No.2

The warship's combat system is an automated system that can effectively respond to various threats occurring simultaneously on the battlefield. The warship's combat system can provide commanders with the valuable information for command decisions in a timely manner and ensure victory in battle when it has an advantage in time and space domain. In this paper, we will analyze cyber threats that may arise in the warship's combat system, examine the limitations of cybersecurity currently applied to the its combat system, and present cybersecurity reinforcement plans for the its combat system. Until now, the Republic of Korea Navy has applied cybersecurity measures in a bolt-on manner, which is independent of warship's combat system. In order to apply reinforced cybersecurity measures for the warship's combat system, the Risk Management Framework of Korea must be applied from the stage of initial planning stage. We need to internalize reliable cybersecurity technologies into the warship's combat system through close review, and mitigate the level of cyber risk by managing, evaluating, and authorizing them according to predefined security controls. In addition, cybersecurity that can guarantee cyber resilience based on Information Assurance can respond to cyber attacks effectively.

함정 전투체계를 위한 분산처리 환경 기반 메시지 정의 및 관리 시스템의 개발

이주원 한국정보과학회 2017 정보과학회 컴퓨팅의 실제 논문지 Vol.23 No.12

Naval combat systems use real-time processing and compositing of collected information to provide the optimal combat capabilities that maximize survival and ensure mission effectiveness. The software for a combat system has dozens to thousands of components depending on the size of the system, and the communication between the components is achieved via DDS. Although the message interface of the combat system is managed through MDMS, an increase in the system size can result in problems such as the deterioration of the development efficiency. In this paper, we implement XMDMS to operate a distributed processing environment and then solve the problem of the reduction in the development efficiency caused by a load at the server. The experimental results shows that XMDMS improves the processing delay and network performance compared to MDMS. 함정 전투체계는 생존성과 임무효과의 극대화를 위해 수집된 정보를 종합하고, 실시간으로 처리하여 최적의 전투능력을 제공하도록 고안되었다. 전투체계의 소프트웨어 컴포넌트는 함정 규모에 따라 수십 개에서 수천 개에 이르며, 각 컴포넌트 간 통신은 메시지 지향 미들웨어인 DDS(Data Distribution Service)를 통해 이뤄진다. DDS를 통한 전투체계 메시지 인터페이스는 MDMS(Message Define & Management System)를 통해 관리되어 왔으나, 체계 규모가 증가함에 따라 개발 효율이 저하되는 등 다양한 문제점들이 대두되었다. 따라서, 본 논문에서는 분산 처리 환경 운용이 가능한 차세대 메시지 정의 및 관리 시스템을 개발하고, 이를 통해 기존의 문제들을 해결하고자 한다. 실험 결과는 XMDMS(neXt Message Define & Management System)가 기존 시스템에 비해 처리 지연 및 네트워크 성능이 향상됨을 보여준다.

함정 전투체계 운용성 향상을 위한 다기능콘솔 전시기 구성 및 HCI 설계

박대영(Dae-Young Park),정동한(Dong-Han Jung),양문석(Moon-Seok Yang) 한국컴퓨터정보학회 2019 韓國컴퓨터情報學會論文誌 Vol.24 No.12

함정 전투체계에는 레이더 장비, 수중센서 장비, 함포 및 미사일 제어용 무장통제 장비들과 같이 체계를 운용하기 위해 필요한 여러 장비들과 이를 통제하기 위한 다기능콘솔이 구성되어 있다. 다기능 콘솔에는 장비들의 상태정보 전시 및 장비들을 통제하기 위한 HCI 기반의 소프트웨어가 탑재되어 있고, 운용자는 탑재된 소프트웨어를 활용하여 함정 전투체계를 운용한다. 하지만 함정 전투체계를 장시간 운용함에 있어 다기능콘솔 전시기의 구조로 인한 신체적 불편함, 다양하고 복잡한 HCI 구성으로 인한 운용자의 피로도 증가 등 문제점들이 발생하고 있다. 이러한 문제점들은 함정 전투체계 운용성을 저하시키는 중요한 요인이 된다. 이를 해결하기 위해, 본 논문에서는 함정 전투체계 개발자들을 대상으로 한 설문조사를 바탕으로 신체적 불편함을 줄일 수 있는 다기능콘솔 전시기 구조 설계와 운용자의 피로도를 줄일 수 있는 직관적인 HCI 설계 방안을 제안한다. 이로 인해, 향후 함정 전투체계 운용자들에게 편의성을 제공하여 기존 함정 전투체계보다 운용성을 향상 시킬 수 있는 장점을 가진다. The Naval Combat System has several equipment needed to operate the system, such as radar equipment, underwater sensor equipment, guns and missile control and armed control equipment, and a multi function console is configured to control it. The multi function console is equipped with HCI(Human Computer Interaction)-based software for displaying the status information of equipment and controlling equipment, and the operator uses the installed software to operate the Naval Combat System. However, when operating a Naval Combat System for a long time, there are problems such as physical discomfort caused by the structure of the multi function console display and increase in fatigue of the person who operates various and complicated user interface configuration. These issues are important factors in reducing Naval Combat System operability. In order to solve these issues, in this paper, based on a questionnaire survey conducted for Naval Combat System development personnel, multi function console screen design to reduce physical discomfort and HCI design to reduce fatigue and increase intuition are proposed. The proposed design is expected to provide convenience to future Naval Combat System operators and improve operation over existing Naval Combat System.

엄홍섭(Eom, Hong-seob) 한국전략문제연구소 2021 전략연구 Vol.28 No.1

본 연구의 목적은 란체스터 법칙을 활용하여 드론봇 전투체계의 전투효과를 분석하는 것이다. 이를 위하여 드론봇 전투체계의 비전과 운용개념을 확인하였고, 란체스터 법칙의 개념과 활용성을 선행 연구하였다. 그리고 지상 드론봇 전투체계의 전투효과는 국방 M&S 모델을 활용하여 평가하였고, 공중 드론봇 전투체계의 전투효과는 란체스터 법칙을 활용하여 산출하였다. 분석결과, 전투력과 연계된 상대적 전투력을 비교함으로서 국방개혁 2.0의 정책적 시사점을 확인할 수 있었으며, 지상 드론봇 전투체계의 전투효과 및 전투시간과 연계된 공중 드론봇 전투체계의 전투력 함수를 도출할 수 있었다. 본 연구의 결과와 모델을 바탕으로 미래의 드론봇 전투체계에 대한 효과분석을 통하여 소요기획 및 운용개념을 설계하는데 도움이 될 뿐 아니라 비용 대 효과분석을 통한 효율적인 국방획득계획 수립에도 활용이 가능할 것이다. The purpose of this study is to analyze the combat effectiveness of dronebot combat system using the Lanchester’s Law. To this end, the vision and the operational concept of the dronebot combat system were identified, and the concept and utility of Lanchester"s law were analyzed. Subsequently, the ground combat robot effectiveness of the dronebot system was evaluated using the Defense M&S model, and the combat effectiveness of the aerial dronebot system was calculated using the Lanchester’s law. As a result, we could compare the relative combat power linking the combat power and combat effectiveness of the ground dronebot combat system, and the combat power function for the aerial dronebot could be derived in conjunction with the combat time. By applying the results of this study, it is possible not only to help design the planning and operation concept by calculating the effectiveness on dronebot operation in the future, but also to use it for efficient requirements planning through the cost-effectiveness analysis.

모델 검증 시스템을 활용한 함정전투체계 소프트웨어에 일관된 UML 모델 적용 방법에 관한 연구

정승모(Seung-Mo Jung),이우진(Woo-Jin Lee) 한국컴퓨터정보학회 2022 韓國컴퓨터情報學會論文誌 Vol.27 No.5

최근 대규모 소프트웨어 개발하는 데 있어 불명확한 의사소통을 해결하기 위해 가독성이 높은 표준화된 UML(Unified Modeling Language) 모델 중심의 모델 기반 개발 방법이 적용되고 있다. 하지만 소프트웨어 개발자들의 숙련도, 모델 및 모델링 도구의 이해도에 따라 대규모 소프트웨어에 일관성 있는 UML 모델을 적용하기에는 어려움이 발생한다. 이에 본 논문에서는 소프트웨어 개발에 일관성 있는 UML 모델을 적용하기 위한 모델 검증 시스템 개발 방법을 제시한다. 그리고 개발된 모델 검증 시스템을 함정 전투체계 소프트웨어 개발에 일부 적용하여 기능을 입증한다. 모델 검증 시스템은 개발자들이 작성한 모델들을 도메인 특성에 맞게 자동으로 검증할 수 있는 기능을 제공한다. 본 논문에서 제안한 모델 검증 시스템을 사용하면 함정 전투체계 소프트웨어 개발에 좀 더 쉽게 일관성 있는 UML 모델을 적용할 수 있는 장점을 가진다. Recently, a model-based development method centered on highly readable and standardized UML (Unified Modeling Language) models has been applied to solve unclear communications in large-scale software development. However, it is difficult to apply consistent UML models depending on software developers’ proficiency, understanding of models and modeling tools. In this paper, we propose a method for developing a Model Verification System to apply an consistent UML model to software development. Then, the developed Model Verification System is partially applied to the Naval Combat System Software development to prove its function. The Model Verification System provides automatic verification of models created by developers according to domain characteristics. If the Model Verification System proposed in this paper is used, It has the advantage of being able to apply the consistent UML model more easily to Naval Combat System Software Development.

미래 병과체계 개선방안 연구: 육군 무기체계와 전투병과를 중심으로

박용식 광운대학교 방위사업연구소 2021 선진국방연구 Vol.4 No.3

본 연구는 육군 병과별 비전 및 주요 무기체계와 병과체계에 대한 사례 분석을 통해 무기체계 발전추세를 고려한 육군 병과체계에 대한 개선방안을 제시하는데 목적을 두고 있다. 미래는 다영역을 동시 통합하는 모자이크 전과 과학 기술의 발전 등으로 인공위성에 기반을 둔 초연결 네트워크가 구축되고, 지상과 해상․공중을 넘나들며 전천후 다기능 전투를 수행할 수 있는 무기체계가 출현하게 될 것이다. 이로 인해 육․해․공군 모두 공통영역이 확대되고 각 군 또는 제 병과구분 자체가 모호해짐에 따라, 지금까지 독립적으로 운영해왔던 병과 운영개념에서 벗어나 합동성이나 통합성을 추구하는 개념으로의 변화는 필연적일 것이다. 이러한 현상을 진단하기 위해 현행 육군 병과체계의 변천과정을 포함하여 육군에서 발간한『육군비전 2050』을 기초로 병과별 비전과 주요 무기체계에 대한 사례를 분석하였다. 분석결과, 병과별로 신개념의 첨단 복합 무기체계를 발전시켜 나가고 있지만 상대적으로 병과체계에 대한 변화는 거의 이루어지고 있지 않음을 확인할 수 있다. 특히, 감시정찰 - 결심 - 타격을 동시에 수행할 수 있는 복합형 드론과 지능형 자율 전투로봇 등의 출현으로, 전투수행 기능별 병과간 영역확대와 상호 중복성은 더욱 심화될 것으로 전망된다. 따라서 무기체계 발전과 연계하여 미래 육군 병과체계를 개선시키기 위한 해결책을 모색하고, 향후 해⋅공군에도 병과체계에 대한 시사점을 제공하고자 한다. This study aims to suggest an improvement plan for the army branch system considering the development trend of weapon systems through a case analysis of the vision and major weapon systems for each army branch system in R.O.K army. In the future, with the development of science and technology, hyper-connected networks based on artificial satellites would be built, and mosaic warfare, which integrates multiple domains simultaneously, and weapon systems capable of performing all-weather multifunctional battles across land, sea, and air would emerge. As a result, the common areas of the Army, Navy, and Air Force would be expanded, and the division of each army or branch itself would become ambiguous. Hence, it will be inevitable to move away from the branch operation concepts that have been operational until now to seek the concept of jointness or integration. To study this phenomenon, based on the Korean Army Vision 2050 published by the Army, the transition process of the current Army branch system and the cases of vision and major weapon systems for each branch were analyzed. The results of the analysis confirmed that although new advanced complex weapon systems are being developed for each branch, relatively little change has been made to the system. In particular, with the advent of hybrid drones and intelligent autonomous combat robots that can simultaneously perform ‘Surveillance, Reconnaissance - Decision – Strike’, it is expected that the area of expansion and mutual redundancy of combat functions will be further deepened. Therefore, in connection with the development of the weapon system, we will seek a solution to improve the Army branch system in the future and clarify the implications for the Navy and Air Force in the future.

김록한,김세영,이하연 한국기계기술학회 2023 한국기계기술학회지 Vol.25 No.5

Combat-armored vehicles were equipped with an automatic-fire-extinguishing system to ensure the safety of the crew and vehicle from fires on the vehicle. When a fire was occurred, the automatic-fire-extinguishing system automatically detects the fire through sensors and detection lines, sprays a fire extinguisher, and notifies the crew visually and audibly. Recently, there had been cases of automatic-fire-extinguishing systems malfunction on combat-armored vehicles. In this study, in order to resolve the automatic-fire-extinguisher's malfunction phenomenon, ground noise and inter-circuit noise generated from the fire detection line were identified, and the resistance connected on the circuit was revised to remove noise. As a result of resistance revision, the noises was eliminated and the electromotive force difference between input circuits was made constant, thereby improving the malfunction of the automatic-fire-extinguishing system. By applying the result, it was confirmed that the control device sensed a temperature similar to the actual temperature on actual vehicles, and it was confirmed that the automatic-fire-extinguishing system's malfunction phenomenon was not founded in the field vehicles after then.
