The composition of Event-B models

Poppleton, Michael (2008) The composition of Event-B models At Abstract State Machines, B and Z: First International Conference (ABZ 2008), United Kingdom. 16 - 18 Sep 2008. 382 pp, pp. 209-222. (doi:10.1007/978-3-540-87603-8_17).

Record type: Conference or Workshop Item (Paper)


The transition from classical B [2] to the Event-B language and method [3] 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 [5] 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.
