摘　　要：本文简要介绍了目前软件规模度量中使用最广泛的IFPUG(International Function Point Users Group)组织的功能点分析方法FPA(Functional Point Analysis).指出了在实际使用过程中用FPA方法在计算软件项目值调整因子(VAF:Value Adjust-ment Factor)时存在的不足,并给出了具体的改进方法.从而使改进后的FPA方法在对软件规模的估算上更为接近项目的实际开发情况.Currently,there are a great deal of methods in software size measurement,however,the most widely used method is FPA（Functional Point Analysis） of IFPUG（International Function Point Users Group）,which is briefly introduced and the focus of study by this paper.Even though it has a wide application,the FPA has some disadvantages in the process of being used when calculating the VAF（Value Adjustment Factor） of software project.To make an improvement to the disadvantages,this paper aims to make an analysis and tries to overcome them by improving FPA method.The results showed that the improved method the paper is discussing based on the FPA method in estimating the software size is more closely functional on the factual development of the situation.
