COCOMO模型在软件维护成本及进度估算中的应用

Application of COCOMO in software maintenance cost and schedule estimation

准确的成本和进度估算是保证软件维护正常进行的必要手段。从技术和非技术两个方面分析了影响软件维护成本的十二条因素,以表格的方式列出了影响维护成本因素的工作量权重;给出了软件维护基本成本模型和改进成本模型;最后给出了半分离式维护进度估算公式及维护进度曲线。

Accurate cost and schedule estimgations are the necessary steps to ensure normal software maintenance. Twelve factors affecting software maintenance are analyzed in technical and non-technical terms,and are listed in tabular form. Both basic and improved cost models are offered,and half-detached maintenance schedule estimation formula and maintenance schedule curve.
