title: Decomposition Tool for Event-B creator: Silva, Renato creator: Pascal, Carine creator: Hoang, Thai Son creator: Butler, Michael subject: Composition and reuse subject: Model construction description: Two methods have been identified for Event-B model decomposition: shared variable and shared event. The purpose of this paper is to introduce the two approaches and the respective tool support in the Rodin platform. Besides alleviating the complexity for large systems and respective proofs, decomposition allows team development in parallel over the same Event-B project which is very attractive in the industrial environment. publisher: John Wiley & Sons, Ltd. date: 2011-02 type: Article type: PeerReviewed relation: http://eprints.ecs.soton.ac.uk/21714/ identifier: Silva, Renato and Pascal, Carine and Hoang, Thai Son and Butler, Michael (2011) Decomposition Tool for Event-B.
