| 针对如何从现存的系统中提取构件的问题,提出了一种基于有向带权图迭代分析的面向对象系统分解方法.它将面向对象系统抽象为一个有向带权图,使用迭代算法考察不同粒度的子图的独立性,并选择独立性高的作为候选构件.实验结果表明,该方法是一种有效的系统分解方法,在准确性上比现有系统分解方法有所提高. |

| Abstract: |
| Aiming at the problem of how to acquire components from existing systems, this paper proposes a decomposition method for object-oriented systems based on iterative analysis of the directed weighted graph. This method uses the directed weighted graph as the representation of object-oriented systems, and an iterative algorithm for analyzing the independence of sub-graphs at different granularity levels. Those highly independent ones are chosen as candidate components. Experimental results show that this method is effective and can improve the existing decomposition methods in terms of accuracy. |
