The temporal logic language XYZ/E can represent both high level and low level specifications in the same framework, so that the specification and implementation of software systems are very convenient. A specification and an implementation of the Steam Boiler Control Specification Problem in XYZ/E is presented in this paper. A visual user interface is also implemented.展开更多

It supports the whole process of program development, i.e. from the abstract specification to the efficiently executable program in a formal, precise and convenient way. The steam boiler control specification problem, a large case study in the fields of real time, hybrid and communication systems, is discussed with XYZ/E. The approach covers physical model construction, formal specification, stepwise refinement, verification, executable program and visual user interface programming.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
