Abstract

Event-B developments are mostly structured around the refinement relationship. This top-down development architecture enables system details to be gradually introduced into the formal model. However, this results in large models with monolithic structures. We develop a composition mechanism allowing to develop models bottom-up. In particular, our proposed mechanism works seamlessly with the existing refinement technique in Event-B. As a result we have built a formal development method that can take advantage of both top-down and bottom-up approaches. We prove the correctness of machine inclusion with refinement using the supporting Rodin platform.
