Component Refinement and Its One Type in the Model of EOOPN

This paper studies the issue of component refinement on the bases of component evolution processes that has been proposed in authors previous research work focused on Extended Object-Oriented Petri Net. Components are refined through basic elements of software system's architectural components. The detailed idea of component refinement is discussed and a set of methods and rules relating to component refinement are provided under the framework of EOOPN model.
