The invention discloses a software reliability modeling method based on moving points and imperfect error removing and relates to the field of software reliability growth model research. The method specifically includes the steps that firstly, software reliability modeling basic assumed conditions based on the moving points and imperfect error removing are proposed; secondly, a fault introducing rate function and a fault removing function are obtained according to the imperfect error removing phenomenon in the software testing process; thirdly, a software reliability growth model based on the moving points and imperfect error removing is obtained according to the moving point phenomenon; fourthly, a progressive adjustment method is used for obtaining the number and the positions of the moving points according to the moving point judging criteria; finally, a set of data which are published are used for verifying the precision of the model. The experiment result shows that the software reliability growth model has the better fitness effect and predictive ability.
