BP算法改进及在软件成本估算中的应用
Improvement of BP Algorithms and Its Application in Software Cost Estimation
摘要
Abstract
Software cost estimation plays an important role in the software development process,which is an effective measure to control software progress and reduce software risk and ensure software quality. Software cost estimation is a complicated task,affected by many factors and uncertainties. According to the current situation of software costs are difficult to estimate,a study based on BP algorithm is car-ried out. Firstly,BP algorithm principle and mathematical representation is researched. Then,based on the analysis of existing problems on BP algorithm,the adaptive learning rate,the additional momentum method and simulated annealing,and genetic algorithm are combined to improve it. Finally,the software cost estimation index system is established and the improved BP algorithm is used in software cost esti-mation. The results show that the improved BP algorithm has the advantages of accurate estimated result,saving manpower and material resources,reducing waste of money,to accelerate software development progress and improve software quality with an important role.关键词
