The Systems Engineering method is increasingly recognized as a central in the Acquisition of Weapon Systems in South Korea. Because of these trends, issues concerned with improving weapon system design are increasingly raised. This paper presents a development of Operational Mode Summary/Mission Profile (OMS/MP) in terms of Weapon Systems Acquisition for application to Systems Engineering method. For a systematic approach, a precise concept of OMS/MP is derived by analyzing the concept of conventional OMS/MP. This paper reviews the results of a series of previously reported examples aiming to develop the OMS/MP of a weapon system. Based on this, the limitations of the conventional OSM/MP applications are investigated. And these limitations can be resolved by the Fundamentals of Systems Engineering. Finally, the OMS/MP framework based on the Fundamentals of Systems Engineering has been proposed and is successfully implemented for the Harbor Underwater Surveillance System.

In principle, R&D of general weapons systems are led by companies or government-funded organizations. In terms of project execution, the defense R&D planning system was reorganized to conduct SE-based project management by integrating the naval ship project execution procedure into the general weapon system R&D procedure. The development progress was confirmed according to the guide for SE application of DAPA, and a technical review meeting was proposed to enter into the each next phase in the R&D process. This paper focuses on improvement for technical review in terms of technical management based on system engineering for R&D mounted weapon systems and the naval surface ship project in preliminary design and detailed design. So, the improvement direction for reviewing the entry criteria for the R&D weapons systems of the naval ship and mounted weapons is proposed.

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.

본 논문에서는 함정 선체의 갈바닉 부식 전류에 의해 발생되는 수중 전기장 신호를 경계요소 해석 도구인 FNREMUS 소프트웨어를 이용하여 예측하고, 예측된 신호로부터 함정 전기장 신호 특성을 특이치 분해(singular value decomposition) 방법을 이용하여 등가적으로 다이폴 모델링하는 방법에 대해 기술하고 있다. 제안된 다이폴 모델링 기법은 30 m 심도에서 예측된 경계요소 해석 결과와의 평균 차이 비교 방법을 통해 타당함이 확인되었다. 본 논문에서 제안된 모델링 기법을 이용하면 함정에서의 다양한 심도 변화에 따른 수중 정 전기장 신호 분포 특성 예측 및 분석이 가능하다.

The weapon system applies the rule that the system engineering procedure must be applied at the acquisition stage. Naval ships, which are one of the important naval weapon systems, take a long period of time to acquire, and the leadership must be commissioned. Therefore, in order to acquire a naval ship, high risk management is necessary, and it is necessary to promote business success through effective application of system engineering which is a scientific management method. However, in the case of naval ships, there are no specific procedures and methods for applying the system engineering. Therefore, research on application method of system engineering which can be easily used by person in charge is necessary. This should have a simple approach to ensure effective business performance by systematically refining and simplifying existing works. QFD (Quality Function Deployment) is a way to improve product satisfaction, impress customers, reduce defective products, reduce design errors, and reduce costs. This systematically develops these mutual relationships by converting the needs of customers into quality characteristics of products and defining them as the design quality of products considering the functions, quality, and process elements of parts. The purpose of this research is to present concrete methodology at the practical level using QFD in a way to ensure traceability of requirements which is an important element of system engineering.

무장통제 소프트웨어는 무장체계와 연동하여 함정 전투체계 내 무장 운용을 지원하는 기능을 수행한다. 무장통제 소프트웨어는 무장체계에 의존적이므로 연동 정보 변화에 따라 소프트웨어 수정이 필연적으로 이뤄지는 특성을 가진다. 소프트웨어의 수정은 신뢰성 시험과 같은 검증 단계를 반드시 거쳐야 하므로 개발 비용의 상승을 초래한다. 본 논문에서는 기존 무장통제 소프트웨어의 수정 요소를 최소화하기 위해 무장통제 소프트웨어 표준 아키텍처를 설계하였다. 연동 정보 관리를 위해 휘처 모델(Feature Model)로 공통요소와 가변요소를 구분하였고 디자인패턴 중 전략 패턴(Strategy Pattern)을 적용하여 소프트웨어 구조를 개선하였다. 소프트웨어 평가 실험을 통해 제안한 아키텍처가 기존 무장통제 소프트웨어보다 개발 비용이 감소하고 변경용이성과 재사용성이 향상된 것을 확인하였다.

국방과학연구소는 해군 전투실험을 위한 시뮬레이션 통합개발환경(QUEST)을 개발하였으며 본 논문은 QUEST의 수중교전 시뮬레이션을 응용을 위한 해군무기체계 모델 라이브러리 개발에 대하여 기술한다. 모델은 기본적으로 함정 및 무장체계 간의 수중교전 효과도 및 전술 개발 목적으로 개발되었다. 수중교전 임무공간과 기존 운용모델 기능 분석을 통하여 표준 모델구조를 정립하고 구성 컴포넌트를 개발하였다. 각각의 컴포넌트는 무기체계 구성부의 기능을 잘 정의한 표준화된 체계, 부체계, 알고리듬 모델이며 모델간 표준 인터페이스를 정의하였다. 모델 라이브러리를 이용하여 사용자는 최소한의 도메인지식으로 기존 모델을 재사용하고 새로운 모델을 효율적으로 조립가능하며 사용자간에 모델을 공유하고 협업할 수 있다.

Recently, the increased use of anti-ship guided missiles, a weapon system that detects and attacks targets in naval engagement, has come to pose a major threat to the survivability of ships. In order to improve the survivability of ships in response to such anti-ship guided missiles, many studies of means to counteract them have been conducted in militarily advanced countries. The integrated survivability of a ship can be largely divided into susceptibility, vulnerability, and recoverability, and is expressed as the conditional probability, if the ship is hit, of damage and recovery. However, as research on susceptibility is a major military secret of each country, access to it is very limited and there are few publicly available data. Therefore, in this study, a possibility of estimating the susceptibility of ships using an anti-air defense system corresponding to anti-ship guided missiles was reviewed. To this, scenarios during engagement, weapon systems mounted to counter threats, and maximum detection/battle range according to the operational situation of the defense weapon system were defined. In addition, the effectiveness of the anti-air defense system and susceptibility was calculated based on the performance of the weapon system, the crew's ability to operate the weapon system, and the detection probability of the detection/defense system. To evaluate the susceptibility estimation feasibility, the sensitivity of the detailed variables was reviewed, and the usefulness of the established process was confirmed through sensitivity analysis.

Naval ships are complex weapon systems which play the integrated performance by system integration of many kinds of weapon systems and their leading ships are usually not disposed after test and evaluation but militarised. Then, strict project management is required for naval ship building projects by identifying problems early and by taking prefer measures in time against unexpected situations encountered in the process of the projects. EVMS is a project management system which can manage the schedule and the budget of a project concurrently and estimate the project's time duration and the cost at project completion. In this paper, the applicability and usefulness of WMS is studied for a assumed navai ship building project, in the environment of monetary fluctuations such as price index, wage increase rate and exchange rate.
