Abstract:

Traditional software reliability models did not consider the severity of the fault affected the reliability of software. However, in many occasions, such as software trustworthy study, we must consider not only the software failure rate, the total number of faults, and failure interval time, but also the severity of the impact on software reliability. For solving the above problem, we propose a prediction method based on Markov chain, which can be used to predict the software failure types, that is, to predict software failure severity occurring in the future.This classification prediction method can fully describe failures caused by software failure.

Key words: software reliability, Markov chain, severity, software trustworthiness
