Formal models and speci-fications of software architecture are one of the key research areas of software architecture. In this paper, the exten-sion of XYZ/E Language based on set theory, called XYZ/E+ Language, is proposed, and a method of formalizingsoftware architecture whit it is formulated. The formal method is distinguished by its ability to represent not onlystatic properties but also dynamic behaviors, and its high-level abstraction and powerful expressiveness. Finally,through an example of formalizing software architecture of a specific system with XYZ/E+ Language, its powerfulmodeling ability and good practicality are demonstrated.展开更多

It provides a model of the large-scale structural properties of systems. Recently, software architecture has been an important research sub-field of software engineering. In this paper,our research work focus on refinement methods of software architecture. By studying the several refinement methods for software architectural design,we present a component-based refinement method that refines an architectural design by replacing a component's static semanucs to its dynamic semantics.展开更多
