The ROK Navy is seeking to secure an aircraft carrier(CVX) to take responsibility for the maritime security of the Republic of Korea. In order for the CVX to complete the mission given to it, the crew must be able to operate the CVX perfectly, and for this purpose, the operating skills of the CVX crew result from constant training. Therefore, this paper proposes an On-board Training System(OBTS) so that the best training can always be performed even on ship. CVX OBTS should be built in the form of a thorough simulator based on a Synthetic Training Environment(STE) so that it can be optimally applied to ship and provide the best training environment to the crew. In order to satisfy the various training requirements and implementation conditions of the CVX, this paper proposes a plan to consist of Embedded Training System(ETS), VR training system, AR maintenance system, MR training system, MR metaverse training system, and realistic simulator training system.

Most weapons systems that are Force Integration are expensive equipment that reflects the latest technology, and the operation and maintenance cost is increasing continuously. Factors that efficiently operate and maintain these weapon systems include maintenance plans, economic costs, and repair part requirements. Among them, predicting the repair parts requirements during the life cycle in advance is an important way to increase operation and maintenance cost efficiency and operating availability. The start of requirement analysis for repair parts is a calculation of the CSP (CSP: Concurrent Spare parts, CSP hereafter) that is distributed when the weapon system is deployed. The CSP is an essential component of achieving the operating availability during this period because the weapon system aims to successfully perform a given operation mission without resupply for an initial set period. In the present study, the CSP calculation method was analyzed, reflecting the failure rate and operating time of items, but the analyzed CSP was aimed at preparing for technical failure, but in the initial operating environment, it is limited in coping with unexpected failures caused by human error. The failure is not included in the scope of free maintenance and is a serious factor in making the weapon system inoperable during the initial operation period. To prevent the inoperable status of a weapon system, CSP that considers human error is required in the initial operating environment, and the calculation criteria and measures are proposed.

설계가 잘된 개방형 무기체계는 마치 자동차의 타이어 교환처럼 신 기술이 적용된 부품을 모듈로써 쉽게 교환해 넣을 수 있기 때문에 기술의 진부화도 걱정할 필요가 없고 나아가서는 부품 공급업체를 걱정하지 않아도 된다. 동일한 인터페이스를 사용하여 구성품간의 상호운용성 보장하고 비용절감과 군수지원성의 이점을 살릴 수 있게 된다. 그러므로 우리가 무기체계를 개발할 때 개방형 체계접근방법을 적용한다면 무기체계를 운용하는 기간 중에 발전하는 기술을 최대한 활용할 수 있는 방법을 갖게 되는 것이다.

BCMS의 변경관리에 대한 요구사항은 ISO 22301 구성체계의 기획단계인 6.3 변경의 기획에서 수행하고, 기업재난관리표준 구성체계에서 기획단계인 3.5.5 문서화된 정보에서 수행하도록 규정하였으며, 이는 모두가 P-D-C-A 운용 모델의 Plan 단계에 해당된다. 이러한 구성체계는 BCP를 최초에 수립하는 단계에서는 적합하지만, BCP가 수립(제정)되어 운용단계에서 발생되는 변경사항을 처리하는데는 많은 문제점이 도출된다. 따라서 재난 및 안전관리 분야에 해당하는 유사제도의 요구사항을 대상으로 비교분석을 통하여 도출된 개선방안을 연구결과로 제시하고자 한다. BCP를 수립하는 과정에서 발생하는 보완사항은 변경관리 절차에 포함하지 않고, BCP가 수립되어 운용단계에서 발생되는 변경사항만 변경관리 절차에 포함하여 관리하며, P-D-C-A 운용 모델의 Act 단계에서 수행하는 것이 적합하다.

This paper proposes the environment construction and test method of system integration laboratory (SIL) and system integration test (SIT) for verification of interface between onboard equipment and ground control equipment of unmanned aerial systems (UAS). This research also describes the interface environment between subsystems built in SIL and verification methods for the systems' operation logic through simulated flights. Similarly, the paper handles the ground integration test process of UAS in the real testing environments.

While developing the military intelligence systems, inter-operation problems which are even existed in the advanced countries must be secured. So we intend to contribute the development of concerned theories by suggesting the process and results of the operational architecture(OA) in C4ISR architecture framework that U.S. military researched and setup based on C4ISR architecture framework theory and BPR methodology.

Required Operational Capability(ROC), which means the performance of a weapon system, is determined when estimating the requirements of a new weapon system. It is very important to define the ROC as it has a decisive influence from acquisition of a weapon system to tactical operation. In this study, we propose a simulation methodology to verify the ROC of the Para-Observation Munition(POM), a newly developed weapon system. To this end, we propose a discrete-event simulation model that takes main performance of the weapon system constituting the ROC and environmental factors that affect performance of the weapon system as input values, and outputs operational effect as a result value. It describes various simulation logic required to implement a simulation model, and explains how to verify ROC using various simulation results such as sensitivity analysis. POM is a weapon system that does not have a similar one and that is difficult to directly utilize the military analysis model. This study can be used as a methodology to analyze the ROC and predict operational effects of weapon systems such as POM.
