A Software Reliability Mixture Model Based on Change-point
Qu Fei · Jisuanji fangzhen · 2009
In view of the problem that single model,which doesn't adapt to a tiny diversity of software project,will make the forecast inconsistent with the fact,this paper studies software reliability mixture model. It proposes a software reliability mixture model based on change-point,analyses and gives a LSM calculating method for change-point estimation. Finally,the model based on change-point is simulated according to a set of data. The result of simulation indicates that the mixture model based on change-point in this paper is better than any of its component models and can overcome the problem that software reliability model isn't reliable enough to be applied to dealing with practical project.
