Feature Model-driven Method of Component Composition and Optimization for Internetware

The method of feature-oriented domain analysis can support efficiently ordering resources for Internetware.In terms of domain engineering,a feature model-driven method of component composition and optimization was proposed,in which the i-Jackson graph was used to describe the feature model of Internetware,and a transformation mechanism from feature model to business component-oriented composition model based on workflow graph was presented.By employing graph theory,the component composition structure graph centering on domain feature cluster was put forward on the basis of composition model.A multi-objective QoS model was defined,and the mathematical model of component composition was established for Internetware in Internet environment,and ant colony optimization algorism was introduced to solve the global optimization problem.Finally,prototype and related experiments proved that this method was feasible and effective.
