Abstract: High quality component is the basic guarantee for efficient software development. Existing component measurement mainly focuses on the external quality, such as dependability and reusability. However, there is not much research on the internal quality of the component. Moreover, there is no synthetic evaluation approach of the internal quality. This paper presents an evaluation approach of the internal quality based on fuzzy inference engine. In this approach, we blur the static analysis of component code and simulate experts’ fuzzy inference in order to estimate the synthetic internal quality. By adopting this approach in the iterative development of components, the measurement of components can be processed automatically, and the timeliness can be improved greatly.

Key words:  component measurement, fuzzy logic, inference engine
