This paper is concerned with event refinement in the context of CSP@?B. Our motivation to include this notion within the CSP@?B framework is the desire to increase flexibility in the refinement process. This approach provides the ability to change the events of CSP processes and B machines when refining a system. Notions of refinement based on traces and on traces/divergences allow abstract events to be refined by sequences of concrete events. A complementary notion of refinement between B machines is also proposed, yielding compositionality results for refinement of CSP@?B controlled components. The paper also introduces a notion of I/O refinement into our event refinement framework.
