Metric-based Evolution Analysis and Evaluation of Software Core Assets Library

The core assets library is the most important component of any software product line; it evolved responding to organization businesses, origination object, technology renovation and time. From the metric of the core assets library, this paper gives several measurements and their definitions which correlate with the evolution of a core assets library. It is combing with data processing, putting forward an evaluation model with the evolution of a core assets library,using analytic hierarchy process to estimate the core assets librarypsilas evolution level, illuminating with an example at last.
