基于结构熵的构件耦合性度量方法

摘要

在基于构件的软件系统中,耦合性是软件中各个构件之间相互关联程度的一种度量.为了能够较好地对软件系统中构件之间的耦合性进行度量,首先对基于构件的软件系统进行形式化表示；然后,对软件系统中的构件之间的耦合关系进行分析；最后,提出结构熵的概念和一种基于结构熵的构件耦合度的度量方法.%component-based software system, coupling is the measurement of degree of inter-dependence between the components. In order to preferably measure the coupling among components in a software system, first, the formal representation ia adopted upon the component-based software system. Secondly, the coupling relation between the components in the software system is analysed. Finally, the concept of structure entropy is given, and an approach to measure the coupling of entropy-based components is presented.
