초록

본 논문은 소프트웨어 신뢰도 모형에서 다중 변화점을 고려함으로서 미래의 관찰치에 대한 예측 성능을 높일 수 있는 새로운 모형에서 프로그램 에러수의 최우추정량이 유한일 조건을 제시하고, 변화점 추정 방법에 대해 논의한다. 또한, 제안된 모형의 타당성을 조사하기 위해 실제 예제를 통하여 모형 성능을 평가한다.

In this paper, we can see that software reliability model has been improved by considering multiple change-points. The condition for the existence of maximum likelihood estimate of the initial error content of a program is given and the maximum likelihood estimations of multiple change-points are derived. We assess the performance of our multiple change-points model on numerical applicaiton.
