【摘要】 针对目前的软件规模度量方法中存在的主观性强、可重复性差的问题,通过将UML引入到度量过程中来改善当前的软件度量方法。分析UML主要部件(用例图、类图和时序图)的语义和COSMIC-FFP的主要元素(功能用户、层、边界、数据组和功能过程),建立其间的对应关系,给出15条映射规则,同时还提出基于UML的COSMIC-FFP度量步骤。实例结果证明,该方法能客观有效地度量软件功能规模。更多还原

【Abstract】 Aiming at the existing problem of strong subjectivity and weak repeatability in software estimation by introducing Unified Modeling Language(UML) into software estimation,this paper analyses the semantics of UML artifacts(use case diagram,class diagram and sequence diagram) and primary elements of COSMIC-FFP(functional user,layer,boundary,data group and functional process) and establishes the mapping from UML artifacts to COSMIC-FFP elements.As a result,15 mapping rules are proposed.This paper proposes a UML-based measurement processof COSMIC-FFP and presents an example for that.Experimental result shows that it is effective and objective to the software estimation.更多还原
