An Extended Feature Modelling Based Component Model for Performance Evaluation

摘要

Traditional component modelling methods focus emphatically on the precise and formal descriptions of business semantics, while usually cannot support to conveniently evaluate the reuse performance of components. Our main concern is to present a new component model for measuring performance after components being designed and before practically reused. The proposed model uses the Extended Feature Modelling method (Ext-FM) to express business semantics and uses variation point to express component¢s reuse mechanism. Some example metrics for component reusability are addressed briefly to validate the effectiveness of this model. Keywords: Component model, extended feature modelling, variation point, reusability metrics.  Received August 28, 2005; accepted April 13, 2006
