非基于软件复用的成本估算模型的复用改造模型及模型系数修正策略

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,但将软件复用考虑进成本估算的模型较少。提出一个基于软件复用的成本估算模型,并应用该模型对COCOMO模型进行复用改造,之后通过实例进行验证。给出了使用存储过程技术对模型参数进行修正的策略,以为各类基于复用的软件开发成本估算提供依据。

Non-reuse-based Software Cost Estimate Model's Reuse Transformation and Model Coefficients Modification Strategies

As an important measure to control and manage software development cost, software cost estimate technolo- gy has become an important issue in software engineering. Currently software development based on reuse is becoming mainstream of software engineering, but few software cost estimate model takes the reuse factor into account. This pa- per proposed non-reuscbased software cost estimate model's reuse transformation model and applied the model to moth fy COCOMO,then used it to estimate an instance project cost. The paper also showed the strategy of using stored pro- cedure technology to calibrate model coefficients. I}his model can provide a reference to various software development and reuse cost estimation.
