Abstract

The number of test samples was calculated by setting the reliability growth management test period considering the weapon system development period. The optimal reliability growth management test design condition was 80% reliability, 60% confidence level, and 6 months of test period. At this time, it was analyzed that 4 test samples were required if 0 failure occurred, and 9 test samples were required if 1 failure occurred. Using the method of determining the number of samples presented in this paper, it can be used as a basis for acquiring a budget for the number of samples for reliability growth management when switching from the exploratory development stage to the system development stage.

무기체계 개발기간을 고려한 신뢰성 성장관리 시험기간을 설정하여 시험 시료 수를 산정하였다. 최적의 신뢰성 성장관리 시험 설계 조건은 신뢰도 80%, 신뢰수준 60%, 시험기간 6개월이었다. 이 때, 고장이 0번 발생하는 경우 시험 시료 수는 4개, 고장이 1번 발생하는 경우 시험 시료 수가 9개가 필요한 것으로 분석되었다. 본 논문에서 제시한 시료 수 결정 방안을 활용하면, 탐색개발 단계에서 체계개발 단계로 전환 시 신뢰성 성장관리 시험 시료 수 예산을 확보하는데 근거로 활용 가능하다.
