【摘要】 为了得到软件项目可靠的成本和工作量的估算,有很多选择,分解技术和经验模型是也可行的办法。文章通过对分解技术和经验模型中常使用的估算方法分别做了定义。最后通过对一个机械CAD软件进行估算,比较了分解技术的估算方法和经验估算模型中的软件方程式模型结果,理想的情况是同时使用多种技术,相互进行交叉调和,能得到更精确地估算。更多还原

【Abstract】 In order to get the estimation of reliable cost and workload,we have many choice.Decomposition technique and com-parison of experience model also are feasible measures.This paper defines the measures of Decomposition technique and comparison of experience model.With a estimation of a mechanical CAD software,we compare the model equations between the decomposition technique and comparison of experience model.The best situation is to use several techniques,crossing blend with each other,and getting more precise estimation.更多还原
