본 논문에서는 선진 제품의 신뢰성 수준과 국산 제품의 신뢰성 수준 비교 결과를 정량적으로 표시하기 위한 신뢰성지수를 개발하여 제안하였다 본 연구에서 제안한 신뢰성지수는 가장 우수한 제품의 신뢰성수준과 비교하고자 하는 제품의 신뢰성 수준을 점수화한 신뢰성점수의 비로서 나타낸다. 이 때 신뢰성점수는 제품 초기 특성값 산포, 환경시험 후의 특성변화율, 제품 설계 여유도, 제품 수명 또는 고장률의 4가지 항목을 고려하여 미리 정한 점수 산출 기준을 통하여 산출한다. 제안한 신뢰성지수의 적용방법에 대한 이해를 돕기 위하여 구체적인 적용례도 함께 제시하였다.

In general, the performance of a component degrades as time goes by and failure of a component occurs when the performance degradation reaches a pre-specified level. It is difficult to obtain the failure time distribution data or the necessary number of failure data especially for the metal or machine part. Thus, a design of reliability qualification test based on performance distribution is more effective than failure time distribution. In this study, a performance-based reliability qualification test is developed and a numerical example is provided to illustrate the use of the developed reliability qualification test. This approach could be applied to many kinds of metal or machine part whose magnitude of strength could not be evaluated during at any random points but judgement can be made by only failure of the part. Besides, it is also possible that any parts which have a similar failure characteristics could be applicable to the developed reliability qualification test.
