摘要
在基于商业构件的软件开发中,构件评估与选择是贯穿整个开发过程的关键步骤。该文提出一种基于差异分析的构件评估方法,通过辨识构件与需求在功能性上的差异,由功能点模型估算以软件功能规模度量的差异及其相应的修正代价。构件对需求的适应度被定义为符合需求的目标系统的功能规模与以功能规模度量的构件总代价的比率。
Commercial Off-The Shelf(COTS) component evaluation and selection is a key step in COTS-based software development. A new method for COTS evaluation and selection based on Gap analysis is proposed. The gap of functionality between COTS and requirements and corresponding adjustment cost are measured in function point model. The fitness of COTS to requirements is defined as the ratio of the software size of target system to the total "cost" of COTS that is also measured in software size. An example with hypothetical data is used to demonstrate the proposed approach.
