构建基于软件过程的成本模型

A COST MODEL BASED ON SOFTWARE PROCESS

在分析COCOMOⅡ模型的基础上,提出了一个基于软件过程的成本模型,其中的数量模型既可以避免COCOMO模型度量的复杂性,又可以根据实际数据描述非线性的成本与驱动因素之间的映射关系。该模型还描述了在实际软件过程中成本度量方法,以及利用过程成本度量数据实现估算和成本控制的机制。

After analyzing shortcomings of COCOMO Ⅱ ,the paper provides a cost model based on software process. Its quantity model can avoid the measurement complexity exiting in the COCOMO,and can describe nonlinear relationship between software effort and cost drivers. The paper then presented the metric approach in software process, and how to apply the model .to cost estimate and cost control.
