摘要

Event-B开发主要是围绕细化关系构建的。这种自顶向下的开发体系结构使系统细节能够逐渐引入正式模型。然而，这将导致具有整体结构的大型模型。我们开发了一种组合机制，允许自下而上地开发模型。特别地，我们提出的机制可以与Event-B中现有的细化技术无缝地工作。因此，我们已经建立了一个正式的开发方法，它可以利用自顶向下和自底向上的方法。利用配套的Rodin平台，通过细化证明了机器包含的正确性。

A Composition Mechanism for Refinement-Based Methods

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.
