摘要： 提出了一种由软件功能需求驱动的评估和选择商业构件(COTS)的新方法。该方法首先基于FCD方法将系统的功能需求分解到各个功能模块。对每个功能模块,识别出一组候选构件,用户根据给定的模板评价候选构件对功能需求的满足度和构件功能的有用性。最优构件组合在给定成本约束下,具有最大的全局需求满足度。选择最优组合的过程是求解一系列优化问题的过程。最后用一个例子进一步说明和验证了该方法。

Abstract: In this paper,a new method for COTS evaluation and selection based on functional requirements is proposed.The approach initially decomposes the system into functional modules in order to identify a group of candidate COTS for each module.The fitness and usability of candidate COTS are evaluated according to the predefined templates.The most promising combination of COTS with maximal global fitness is determined under the global cost constraint.Finally,an example with hypothetical data is used to demonstrate and initially validate the proposed approach.
