The transition from classical B  to the Event-B language and method  has seen the removal of some forms of model structuring and composition, with the intention of reinventing them in future. This work contributes to that
reinvention. Inspired by a proposed method for state-based decomposition and refinement  of an Event-B model, we propose a familiar parallel event composition (over disjoint state variable lists), and the less familiar event fusion (over intersecting state variable lists). A brief motivation is provided for these and other forms of composition of models, in terms of feature-based modelling. We show that model consistency is preserved under such compositions. More significantly we show that model composition preserves refinement.
