摘　　要： 分析软件柔性及特性,从面向用户的角度给出柔点的定义及识别方法,对面向用户的柔点进行分类。为度量柔变范围,提出一个以柔点为核心、以功能规模单元为度量单位的面向用户的定量度量模型。模型对功能点分析法进行改进,引入数据移动、数据组及数据属性,解决了柔变范围定量度量问题,对软件柔性的评价具有重要作用。结合实例描述了柔变范围的度量过程,分析了度量结果。 Software flexibility and its characteristics are analyzed,a new definition of flexible point and it＇s recognition from the useroriented view are given,and the user-oriented flexible points are classified.To measure the flexible range,a model based on useroriented flexible point,using functional size unit as the uint of measurement,which can quantitatively measure the flexible range from user-oriented view,is given.The FPA is improved by using movement,collection and unit.The quantitative measurement of flexible range is solved,and it has important influence on the appraisal of software flexibility.An actual case is carried out to illustrate the analysis and measurement of flexible range,and the result is analyzed.
