基于领域空间的软件复用成本估算模型

Software Cost Estimate Model Based on Reuse and Domain Spatial

作为软件成本控制管理的重要措施,软件开发成本的估算技术已经成为软件工程领域的一个重要课题,当前基于复用的软件开发正在成为软件工程的主流。论文通过对COCOMOII模型的改造,建立基于领域空间的软件复用成本估算模型,分析复用技术及复用粒度引起的成本变化,并通过引入领域空间的概念,分析复用成本与时间的关系。之后给出了对模型系数进行本地化校准的方法并通过实例验证模型的适用性。

As an important measure to control and manage software development cost,software cost estimate technology has become an important issue in software engineering.Currently software development based on reuse is becoming mainstream technology of software engineering,This paper modifies the COCOMOII model,establishes the software cost estimate model＇s reuse transformation based on domain spatial which is used to analyze the relationship between software reuse, reuse granularity and cost,the concept of domain spatial is introduced to illustrate the relationship between reuse cost and development cycle.The paper also shows the strategy of using historical data to calibrate model coefficients.Finally,a case study proves the validity and applicability of the model.
