In view of the existing situation of artificial parameter selection in the fitting process which using the LSSVM software reliability model, the combination method of analytic selection (AS) and simulate anneal arithmetic (SA) is proposed for parameter selection, then obtain the improved software reliability model based on ASSA-LSSVM.The ASSA-LSSVM model considers the optimization of the penalty parameters C and kernel parameter in the model, make the model more realistic, and reduce the time cost of artificial selection-parameter.Make use of the published three groups of software failure data to verify this proposed model, the result shows that, compared with the former LSSVM model, the ASSA -LSSVM model can achieve better fitting results.
