Abstract
Mission reliability is defined by the probability of accomplishing the requirements task that were targeted in product development, and in the case of combat systems, mission reliability is an important factor that will determine victory or defeat, unlike commercial equipment. The mission reliability of the existing domestic combat system was calculated by considering only the physical connections of the equipment involved in the mission performance, but as the equipment becomes increasingly sophisticated and complex, it is impossible to determine the mission relevance solely by physical connection. Thus, in this paper, improved mission reliability was calculated using SysML, the system design modeling language, by taking into account the functional connection as well as physical connection. Based on this research, we look forward that the mission reliability of the combat system that will be developed in the future will be used as a verification material.
임무신뢰도란 제품개발 시 목표가 되었던 요구조건하에서 임무를 완수할 확률을 나타내며, 전투체계의 경우 상용 장비와 달리 임무신뢰도가 승패를 좌우할 중요한 요소이다. 기존의 국내 전투체계의 임무신뢰도는 임무수행에 연관된 장비의 물리적 연결만을 고려해 산출되었으나, 장비들이 점차 고도화되어지고 복잡해져 물리적 연결만으로 임무연관성 판단이 불가하다. 이에 따라 본 논문에서는 물리적 연결뿐만 아니라 기능적 연결을 고려한 방법으로 시스템 설계모델링 언어인 SysML을 활용하여 정확도가 향상된 임무신뢰도를 산출하였다. 본 연구결과를 바탕으로 향후 개발되는 전투체계 임무신뢰도 검증자료로 활용 되기를 기대한다.
