【摘要】 为了充分利用组织的历史项目统计数据,同时避免代码行估计和功能点估计的主要缺点,提出了一种基于单元度量的项目估计方法。定义了该方法需要使用的测量项以及测量项的采集方法,介绍了使用指示器进行数据分析以及调整估计因子以提高估计准确度的方法,介绍了使用项目的操作过程数来对项目的规模、工作量等进行估计的方法,并使用来自于载人航天工程的30个实际项目的测量数据对该方法进行了验证,实验结果表明,该方法具有较高的准确度和一致性。更多还原

【Abstract】 To make full use of history statistics and avoid the shortcomings of LOC(lines of code) estimation and function point estimation,a new estimation method of software project based on unit measurement is presented.Firstly,some measurement items used in the estimation are defined and also their collection method is introduced.Secondly,the use of indicators for data analysis and adjustment of estimation factors are described,which can help to improve the accuracy of estimation.Finally,the method of software project estimation is detailed using operation processes of project.30 actual projects of China manned space program plan are used to validate the method and the result shows it has high accuracy and consistency.更多还原
