构建面向对象系统规模评价模型

Modeling size estimation of object-oriented system

分析了现有的软件规模度量特点和应用于OO(Objected-Oriented)系统时存在的问题,提出了类点分析法的规模评价模型,用以评估OO软件产品特性,能精确地捕捉OO的关键概念和结构,并应用在OO的设计阶段,独立于软件开发的技术和设计工具。类点分析法中定义了两个相关联的度量,其目标旨在软件的整个开发过程中,当有效的信息被得到时,能不断地精化评估规模模型,使之精确地预测OO系统的开发代价和项目管理。给出了实施类点分析法的系统规模评估过程。

Taking into account existing software size measures and their defects, Class Point Analysis for estimating the size of object-oriented systems was presented. Two measures were correlatively defined to refine preliminary size estiamtion when more information is available in the development process, as predictor of development effort and management projects. The size estimation process that led to the definition of proposed measures was gived. It turned out to be suitable to capture specific object - oriented feasures, based on design documentation and independent technology.
