摘要
为了解决柔性软件柔点柔变范围度量准确性差和操作性低的问题,以面向用户的柔点为研究对象,提出了软件柔变性模型,建立了柔点变化传播影响图,改进了功能点分析法,给出了柔点柔变范围定量度量模型。在该度量模型中,以柔变部件作为基本度量实体,利用柔变性模型表示柔点、柔变点和柔变项,通过柔点变化传播影响图分析柔点变化传播影响,应用改进的功能点分析法提取软件柔点变化影响的柔变部件,进而计算所有柔变部件的功能点计数,确定柔点柔变范围的定量值。结合实例说明了柔点柔变范围的定量度量过程,分析了柔点柔变范围。
To solve the poor accuracy and the low operability on the flexible point change impact range measurement of the flexible software, a flexible change model was proposed, the flexible point change propagation impact graph was established, the unction point analysis method was improved and a quantitative measure model of flexible point change impact range was proposed by taking the user-oriented flexibte point as the research object. In this measure model, the flexible change components were taken as the basic software metric entities, the flexible points, the flex- ible change points and the flexible change items were expressed by using the flexible change model. The impact of the flexible point change propagation was analyzed by using the flexible change propagation impact graph, and the flexible change components influenced were extracted by using the improved function point analysis method. Through calculating the function point counts of flexible change components, the flexible point change impact range was determined. In addition, an example was given to illustrate the quantitative measure process of the flexible point and analyze the flexible point change impact range.
