| Abstract: | In view of the problem that the precision of software reliability model is not high enough,a new method of 'first modelling + second fitting' is proposed.This method aims to improve the precision of models by error compensation mechanism.The validation of this method has been demonstrated through applying it to aerospace software failure data set and the practical result explained that the method proposed in this article is effective in improving the precision of software reliability models. |
