Abstract. Action refinement in process algebras has been widely studied in the last few years as a means to support top-down design of systems. A specific notion of refinement aris...
This paper introduces action refinement in the context of CSP B. Our motivation to include this notion of refinement within the CSP B framework is the desire to increase flexibilit...
Abstract. In this paper an approach for building process models for ecommerce is proposed. It is based on the assumption that the process modeling task can be methodologically supp...

We automatically verify Back's atomicity refinement law and a classical data refinement law for action systems. Our novel approach mechanises a refinement calculus based on K...
We study the notion of class refinement in a concurrent object-oriented setting. Our model is based on a combination of action systems and classes. An action system describes the b...
