摘要:
 软件成本估算在软件开发过程中扮演着重要角色，它是控制软件进度、降低软件风险和保证软件质量的有效措施。软件成本估算是复杂的工作，受众多因素影响且具有不确定性。针对软件成本难以估算的现状，文中基于BP算法展开研究。首先，研究BP算法原理和数学表示；然后，在分析BP算法存在问题的基础上，将自适应学习率、附加动量项法与退火模拟算法、遗传算法等方法相结合对其进行改进；最后，构建软件成本估算指标体系，并将改进的BP算法应用于软件成本估算。结果表明，算法具有估算结果精确、节省人力物力、减少资金浪费等优点，对加快软件开发进度、提高软件质量具用重要作用。
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.
