--- abstract: "We provide a detailed description of refinement in Event-B, both as a contribution in itself and as a foundation for the approach to simultaneous animation of multiple levels of refinement that we propose.\r\nWe present an algorithm for simultaneous multi-level animation of refinement, and show how\r\n it can be used to detect a variety of errors that occur frequently when using refinement.\r\nThe algorithm has been implemented in ProB and we applied it to several case studies, showing that multi-level animation is tractable also on larger models." accompaniment: [] book_title: Proceedings ABZ 2010 commentary: ~ completion_time: ~ composition_type: ~ conductors_id: [] conductors_name: [] contact_email: ~ copyright_holders: [] corp_creators: [] creators_id: - ~ - leuschel@cs.uni-duesseldorf.de - plagge@cs.uni-duesseldorf.de creators_name: - family: Hallerstede given: Stefan honourific: '' lineage: '' - family: Leuschel given: Michael honourific: '' lineage: '' - family: Plagge given: Daniel honourific: '' lineage: '' data_type: ~ date: ~ date_type: ~ datestamp: 2010-01-11 13:51:00 department: ~ dir: disk0/00/00/01/86 divisions: [] edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 186 event_dates: ~ event_location: ~ event_title: ~ event_type: ~ exhibitors_id: [] exhibitors_name: [] fileinfo: /style/images/fileicons/application_pdf.png;/186/1/multi_refine.pdf full_text_status: public funders: [] id_number: ~ importid: ~ institution: ~ isbn: ~ ispublished: inpress issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: ~ lastmod: 2010-04-19 15:05:59 latitude: ~ learning_level: ~ longitude: ~ lyricists_id: [] lyricists_name: [] metadata_visibility: show monograph_type: ~ note: ~ num_pieces: ~ number: ~ official_url: ~ output_media: ~ pagerange: ~ pages: ~ patent_applicant: ~ pedagogic_type: ~ place_of_pub: ~ pres_type: ~ producers_id: [] producers_name: [] projects: [] publication: ~ publisher: Springer-Verlag refereed: TRUE referencetext: ~ related_url_type: [] related_url_url: [] relation_type: [] relation_uri: [] rev_number: 27 series: LNCS skill_areas: [] source: ~ status_changed: 2010-01-11 13:51:00 subjects: - Refinement - deploy_method_proof - deploy_tooldev_modela - deploy_tooldev_rodinplugins - theory succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ task_purpose: ~ thesis_type: ~ title: 'Refinement-Animation for Event-B - Towards a Method of Validation' type: book_section userid: 12 volume: ~
