Reliability is an important software trustworthy attribute. But most existent reliability model don't consider the severity degree of software fault, so traditional software reliability model can't reflect the trustworthiness of software. Based on the analysis of typical J-M reliability growth model, this paper modifies some of the model assumptions and classifies the software faults. Besides, this paper presents a new method based on weight to calculate the degree of software reliability. Finally, according to the different of frequency of software faults, a practical reliability prediction method is proposed and the experiment results shows that the improved model has a better forecast accuracy. © (2013) Trans Tech Publications, Switzerland.
