| Abstract: | A software reliability assessment method for highly reliable software systems is investigated.As highly reliable software system seldom fails,the failures as rare events is considered,so extreme value theory(EVT) is applied to model the failures.Analysis of rare event data using EVT does not require a priori assumptions concerning the distributional form of the data,and thus provides an interesting alternative to traditional approaches.The feasibility of using EVT in software reliability assessment is investigated,and the appropriate statistical methods is proposed. |

| Keywords: | software reliability highly reliable software statistics of extreme failure data |
