Component-based software engineering has increased the quality and the efficiency in software development. But the component adaptation is still a crucial issue in Component-based software engineering. In this paper, we focus on a dynamic analysis on the change of component and a method detecting the impact on both the correlative component and the whole system. Firstly, the component model and adaptation principle is described in formal specification. Then the connection matrix of component interface is constructed to help us analyze the relationship of interface. Finally, we propose a new dynamic detecting method based on interface matrix. According to the detecting method expressed in this paper, we have developed a tool CIDT, which is used in CBSE to analyze the impact of the component change. © 2008 IEEE.
