Abstract

The software reliability have to be improved as one major method to enhance the quality of developed software, and its defect is detected and modified through testing as a direct way to meet the purpose before releasing. Once its reliability grows up to the target and it is released to public. there nay be operational reliability problem. The operational software reliability trend nay be different depending on the condition whether it is universal or dedicated. And its reliability estimation is changed based on the condition if it follows uniform testing efforts or Weibull testing efforts. I study the operational reliability trend of dedicated software, applying two case testing efforts for the released item.

소프트웨어를 개발하여 출시하기 전에 품질을 향상시키는 중요한 방법으로서 신뢰도를 향상시켜야 하며, 이의 직접적인 방법으로서는 테스트를 통하여 결함을 검출하고 수정해가는 것이다. 신뢰도가 목표치에 도달하면 이를 출시(release)하게 되며, 그 후로는 운영중의 신뢰도 문제가 발생하게 된다. 개발 출시된 소프트웨어가 패키지 소프트웨어라 불리는 범용 소프트웨어냐, 아니면 특수목적을 가진 전용 소프트웨어냐에 따라 운영 소프트웨어의 신뢰도 추이가 달라진다. 또한, 개발 테스트 단계의 테스트 노력이 일정하냐, 아니면 웨이불 곡선을 따르냐에 따라서도 신뢰 도 평가가 다르다. 본 논문에서는 주문형 소프트웨어에 대해서 일정 테스트 노력을 적용하는 경우와 웨이불 테스트 노력을 적용하는 경우의 운영단계 신뢰도 추이에 대해서 연구한다.
