Although, it is widely recognised that formal methods is the single most important technique for building complex dependable systems, formal methods struggle to gain wide acceptance outside their few traditional application areas. In this paper we investigate a method for mechanised transformation of formal models. We argue that, applied to the vast catalogue of architectural and design patterns for dependable systems, this method can greatly contribute to the applicability of formal methods in development of dependable systems. The discussion is supported by a detailed analysis of the Triple Modular Redundancy pattern and a prototype plugin to the RODIN platform which adds the refinement mechanisation support to the Event-B formal framework.
