To ensure the result validity of software project schedule estimation and improve the success rate of software projects,a quantitative and systemic estimation method for software project schedule was studied.This model tries to overcome the inherent shortcomings of three methods and develop their own merits by studying the characteristics of traditional analog method,PERT method and Delphi method.This model set Delphi method as a prototype,combined with PERT method and analogy method during the estimation of the experts.This model could overcome the shortcomings that the big data gaps would cause the analogy method failure and the Delphi method depended too much on the experience of the experts.This model could also overcome the peoples' suspicion of the PERT method's effectiveness.The practical application data shows that the reliability and availability of the estimation result of this model are high.
