The recent notion of Network Centric Warfare (NCW) emphasizes the ability to distribute right information at the right time to maximize the combat effectiveness. Accordingly, in the modern combat system the importance of non-physical element, such as communication system is increasing. However, an NCW-support communication network system is expensive. Therefore, it is essential to develop a proper combat system evaluation method to establish an efficient NCW-support combat system. Traditionally, combat system effectiveness is measured in terms of physical elements such as men and fire power. Obviously, such method is hardly applicable to a modern combat system To overcome this difficulty, we propose an evaluation model based on CA (Cellular Automata) simulation. A set of preliminary combat simulations show that CA simulation may be promising in evaluating non-physical element of a modem combat system.

The shipboard combat system is a key system for naval combat that supports a command and control process cycle consisting of Detect - Control - Engage in real time to ensure ship viability and conduct combat missions. Modern combat systems were developed on the basis of Open Architecture(OA) to maximize acceptance of latest technology and interoperability between systems, and actively introduced the COTS(Commercial-of-the-shelf). However, as a result of that, vulnerabilities inherent in COTS SW and HW also occurred in the combat system. The importance of combat system cybersecurity is being emphasized but cybersecurity research reflecting the characteristics of the combat system is still lacking in Korea. Therefore, in this paper, we systematically identify combat system threats by applying Data Flow Diagram, Microsoft STRIDE threat modelling methodology. The threats were analyzed using the Attack Tree & Misuse case. Finally we derived the applicable security requirements which can be used at stages of planning and designing combat system and verified security requirements through NIST 800-53 security control items.

The threats around Korea Peninsula have been dramatically increased because North Korea is developing the Nuclear ballistic missile, Submarine launched ballistic missile(SLBM), and many kinds of weapons for sudden provocations. Therefore, ROK navy needs the cutting-edge warship combat systems in order to defeat the enemy threats effectively in the sea. The paper analyzes current warship combat system acquisition process and studies US navy and other advanced countries acquisition process and their contraction trends. After that, the paper proposes the optimal acquisition process of warship combat system for the ROK navy based on our current situation and other advanced countries acquisition trends. The paper will dedicate the next generation warship combat system acquisition process.

A naval combat system is the system of systems who supports naval indigenous operations by integrating and inter-operating many different kind of weapons, which has characteristics of large scale complex computing system. ROK Navy has been built a blue ocean navy, so that large scale warships are under constructions. However, warship combat system architecture has not been well studied so far in Korea. The paper focuses on current combat system architecture and propose the next generation combat system architecture, which will give the development direction of ROK Navy. In order to complete combat system architecture studies, the system engineering process shall be applied to the study. Moreover, ARENA simulation tool is used for verification of combat system architecture. The system engineering process is as follows: next-generation naval combat system requirement analysis, functional architecture analysis and physical architecture analysis.

전투 시스템의 생존성은 전투 환경의 여러 요인에 따라 변화한다. 기존의 전투 시스템 생존성 분석 시뮬레이션 프로그램은 전투 환경에 따라 변화하는 생존성의 분석에는 한계를 가진다. 이 논문에서는 이러한 한계를 극복하기 위하여 에이전트 기반 모델링 및 시뮬레이션 기법을 이용한 전투 시스템의 동적 생존성 분석 방법을 제안한다. 시뮬레이션을 위해 DEVS 형식론, SES/MB 프레임워크, 에이전트 기술을 이용하여 전투 시스템을 구성하는 여러 요소를 모델링하고, 전투 시스템에 탑승하는 승무원을 각 역할에 따른 에이전트로 모델링한다. 제안하는 기법을 적용하면, 전투 환경에서의 전투 시스템 정적 생존성을 비롯하여 전투 시스템에 탑승하고 있는 승무원의 대응에 따라 변화하는 생존성을 분석할 수 있다.

본 논문에서는 보안성과 안정성을 유지하면서 함정 전투관리체계의 생존성을 향상시키는 체계접근통제 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.

System integration is an important element for the construction of naval combat ships. In particular, because impeccable combat system integration together with the sensors and weapons can ensure the combat capability and survivability of the ship, the integrated performance of the combat system should be verified and validated whether or not it fulfills the requirements of the end user. In order to conduct systematic verification and validation, a data analysis tool is requisite. This paper suggests the Data Extraction, Recording and Analysis Tool (DERAT) for the data analysis of the integrated performance of the combat system, including the functional definition, architecture and effectiveness of the DERAT by presenting the test results.

In this paper, we propose a new scalable and reliable combat system software in battleship which was developed procedurally in the past. Recently, combat system software is required to change frequently due to addition of new equipment and change of function. To solve those problems, this paper propose how to change combat system software into scalable software using class structure change and design pattern. Simulation results show that our scheme provides better performances and reliability than conventional scheme. Therefore proposed scheme can be efficiently used in Naval combat system.

The Shipyard Test of Naval Combat System depends on external factors, such as weather conditions and availability of its sensor-weapon, due to the need of on-board sensor-weapon during the test. This paper suggests the Supportive Equipment using virtual simulator for Shipward Test, in case of the unavailability of the on-board sensor-weapon or the test support force(aircraft, surface ship etc.), to pre-check the functions of the combat system as well as to prepare the Shipyard Test. To mock the real sensor-weapon functions as similar as possible, the Supportive Equipment for Shipyard Test was verified by the Verification and Validation process, which is usually performed while developing models in the Modeling & Simulation field.
