초록

설계 단계에서 수행되는 신뢰도 예측은 신뢰도를 조기에 추정하여 설계 절충, 신뢰성 성장 및 총수명주기 비용분석을 수행하기 위한 정량적 기반을 제공한다. 특히, 장비가 장기간 비운용 상태인 전원이 공급되지 않는 기간을 고려하여 신뢰도 값이 산출되어야 정확한 장비의 평균 수명을 파악할 수 있다. 본 논문은 비운용 기간 동안을 고려한 전자 장비 신뢰성에 미치는 정량적 영향을 분석하였다. A 조립체의 육, 해, 공군의 운용환경 및 임무주기를 적용하여 신뢰도 값을 비교하였다.

Abstract

Reliability predictions performed during the design phase provide a quantitative basis for early estimation of reliability to perform design compromise, reliability growth, and total life cycle cost analysis. In particular, the average life of the assembly can be accurately determined when a reliability value is calculated taking into account the period in which power is not supplied for nonoperating time. This paper analyzed the quantitative effect on the reliability of electronic assembly considering the nonoperating time. Reliability values were compared by applying the operation environment and mission cycle of A assembly army, navy and air force.
