Formal modelling is indispensable for engineering highly dependable systems. However, a wider acceptance of formal methods is hindered by their in- sufficient usability and scalability. In this paper, we aim at assisting developers in rigorous modelling and design by increasing automation of development steps. We introduce a notion of refinement patterns – generic representations of typical correctness-preserving model transformations. Our definition of a refinement pattern contains a description of syntactic model transformations, as well as the pattern applicability conditions and proof obligations for verification of correctness preservation. This establishes a basis for building a tool supporting formal system development via pattern reuse and instantiation. We present a prototype of such a tool and some examples of refinement patterns for automated development in the Event B formalism.
