基于UML模型的全功能点自动化度量

The Automatic Measurement of Full Function Points Based on UML

软件规模在项目估算和决策中起着举足轻重的作用。基于软件需求从用户角度和功能角度度量规模的全功能,点(FFP)广受欢迎,但为手工操作,弊端显而易见,所以亟需自动化度量。本文提出并实现了基于UML模型全功能点自动化度量系统,不但能得到精确的量化结果,而且能减轻工作量、降低花费,以及很大程度上避免抽取数据及度量过程中差错所造成的风险,更重要的是具有可重复性,从而易于功能规模度量方法的推广。

Software size plays a significant role in project evaluation and decision-making. Full Function Points(FFP) which give a measure of the size of the system by measuring the functionalities from an end-use perspective and a functional perspective .are gaining an increasingly widespread application. Unfortunately FFP calculation is mostly a manual process , so many abuses obviously occur and automatic measurement is demanded very much. This paper presents and implements an automated system for measuring the FFP software metric based on UML. Automation not only gains the more accurate of its size measurement but also lessens the work effort and reduces measurement costs of FFP counts. Secondly automation provides a good opportunity to reduces the risk of errors being introduced into the extracted data ,and the most important thing is it makes repeatability of the results. Thus is important for the acceptance of functional size measurement.
