摘要
软件成本估算从20世纪60年代发展至今,在软件开发过程中一直扮演着重要角色.按照基于算法模型的方法、非基于算法模型的方法以及组合方法的分类方式,全面回顾、分析了软件成本估算的各种代表性方法,也归纳讨论了与成本估算强相关的软件规模度量问题.在此基础上,进一步研究了软件成本估算方法的评价标准,并给出了一个应用实例及其分析.最后,从估算模型、估算演进、估算应用、估算内容、工具支持和人为因素6个方面,指出了软件成本估算方法下一步的主要发展趋势.
Software cost estimation has played an important role in software development since its emergence in 1960＇s. Based on a classification of algorithmic model based methods, non- algorithmic model based methods and composite methods, the typical software cost estimation methods in history are overall reviewed. The issue of software sizing, which is closely related to software cost estimation, is also discussed in this paper. Then a three phases＇ evaluation criterion of software cost estimation methods is proposed and a case study on cost estimation of government sponsored projects in China is analyzed. At last, six possible trends from estimation models, estimation evolutions, estimation applications, estimation contents, supporting tools and human factors, are presented as a primary conclusion in the paper while viewing the future development for software cost estimation.
