항공무기체계 LVC 시뮬레이션을 위한 통합연동시스템 V&V
오지현,장영찬,김천영,지철규,홍영석,Oh, Jihyun,Jang, Young Chan,Kim, Cheon Young,Jee, Cheol Kyu,Hong, Young Seok 한국군사과학기술학회 2015 한국군사과학기술학회지 Vol.18 No.3
This paper describes the verification and the validation about the development of the integrated interoperability system for live, virtual, and constructive simulations on the aircraft weapon system. The proposed integrated interoperability system provides the framework and application softwares for implementing a synthetic environment emulating real-world environment among distributed simulation models, which are a mission model and an air combat model of a constructive level, an tactical simulator of a virtual level, and simulated ACMI of a live level. In this paper, we verify requested functions through an developmental test and evaluation, and validate operability and usability through conducing integrated LVC scenarios on the integrated interoperability system.

확률변수 가중치 환산법 기반 군용 항공기 생존성 분석기법
양주석(Ju-Suk Yang),이경태(Kyung-Tae Lee),지철규(Cheol-Kyu Jee) 한국항공우주학회 2013 韓國航空宇宙學會誌 Vol.41 No.11
군용 항공기의 개발과정 중 전투 생존성 분석은 반드시 거쳐야 할 필수 과정이다. 군용항공기의 전투 생존성 분석을 위한 방법은 M&S 기법 적용이 일반적이며 필요시 최종단계에서 Live Fire Test를 거친다. 본 연구에서는 비용대비 효과도를 고려하여 M&S기법을 통해 개념설계단계에서 신속하게 정성적으로 전투 생존성을 분석할 수 있는 연구를 수행하였다. 본 연구를 위하여 필수사건 및 필수요소 분석기법, 몬테카를로 시뮬레이션 등 확률, 통계기법들을 이용한 ‘확률변수 가중치 환산법’ 알고리즘을 고안하여 제시하였다. Aircraft combat survivability analysis is essential process for the development of combat aircraft. M&S methodology is the typical procedure for the aircraft combat survivability analysis, and the last step is the expensive Live Fire Test if it is necessary. This study introduced cost and time effective survivability analysis methodology based on the random variable weighted score algorithm in conceptual design phase. For this study, essential element and event analysis (E3A) is used to define the random variables and Monte-Carlo simulation is implemented to estimate weighted score and the final value of survivability.

Live-Virtual 시뮬레이션 환경차이에 따른조종사 스트레스 유발요인 분석
김진주(Jin ju Kim),김성호(Sung ho Kim),설현주(Hyeon ju Seol),지철규(Cheol kyu Jee),홍영석(Young seok Hong) 한국산업경영시스템학회 2016 한국산업경영시스템학회지 Vol.39 No.1
Recently, Live-Virtual-Constructive (L-V-C) integrate training system has proposed as a solution for the problems such as limitation of training areas, increase of mission complexity, rise in oil prices. In order to integrate each training system into the one effectively, we should solve the issue about stress of pilots by the environmental differences between Live and Virtual simulation which could be occurred when each system is connected together. Although it was already examined in previous study that the psychological effects on pilots was occurred by the environmental differences between actual and simulated flights, the study did not include what the causal factors affecting psychological effects are. The aim of this study is to examine which environmental factors that cause pilots’ psychological effects. This study analyzed the biochemical stress hormone, cortisol to measure the pilots’ psychological effects and cortisol was measured using Enzyme-linked immunoassay (EIA). A total of 40 pilots participated in the experiment to compare the differences in pilots’ cortisol response among live simulation, virtual simulation, and the virtual simulation applying three environmental factors (gravity force, noise, and equipment) respectively. As a result, there were significant differences in cortisol level when applied the gravity force and equipment factors to the virtual simulation, while there was no significant difference in the case of the noise factor. The results from this study can be used as a basis for the future research on how to make L-V system by providing minimum linkage errors and design the virtual simulator that can reduce the differences in the pilots’ psychological effects.

본 연구에서는 협업기반의 임무 수행 시 유·무인전투기 각각의 역할을 도출하고 복합 운용방안을 제시하기 위한 임무 적합도 평가 방법론을 제시하였다. 유·무인전투기 복합운용을 위한 대표 임무로 SEAD 임무를 선정하고 기체 성능, 장비성능 그리고 자율성 수준을 고려한 성능평가표를 작성하여 유인전투기와 무인전투기의 성능을 비교하였다. SEAD의 세부 임무절차를 구분하여 성능평가표의 항목과 결합된 임무적합도 평가지표를 설계하고, 전문가 설문을 통해 임무적합도를 평가하였다. 평가결과를 통해 세부 임무의 위험성과 중요도에 따라 무인기와 유인기의 적정 역할을 설정할 수 있었고, 이를 바탕으로 조종사의 임무부담을 줄이도록 임무, 통제권, 유·무인전투기의 임무 및 기동을 반영한 시간 기반의 임무계획을 수립할 수 있었다. This paper presents a methodology for evaluating suitability of a manned-unmanned aerial vehicle team for a complicated mission. The study identified vehicle performance, equipment performance and level of autonomy as the key factors that affect the mission effectiveness. A manned and an unmanned aircraft were compared, and their performance was quantized in these respects. SEAD was chosen as a representative manned-unmanned team mission. The SEAD mission was broken down to a sequence of tasks. Mission experts evaluated the importance of each mark item for the mission legs. Combining the results showed proper type of aircraft for each leg depending on the complexity, safety, and importance of the task. Finally, the whole mission plan was laid out as a time-based sequence which alleviate pilot workload significantly.
