--- abstract: "In this article we would like to present some recent applications of the B formal\r\nmethod to the development of safety critical systems, namely platform screen door\r\ncontrollers. These SIL3/SIL41 compliant systems have their functional specification based\r\non a formal model. This model has been proved, guaranteeing a correct by construction\r\nbehaviour of the system in absence of failure of its components. The constructive process\r\nused during system specification and design leads to a high quality system which has been\r\nqualified2 by French authorities." accompaniment: [] book_title: ~ commentary: ~ completion_time: ~ composition_type: ~ conductors_id: [] conductors_name: [] contact_email: ~ copyright_holders: [] corp_creators: [] creators_id: - thierry.lecomte@clearsy.com - thierry.servat@clearsy.com creators_name: - family: lecomte given: thierry honourific: '' lineage: '' - family: servat given: thierry honourific: '' lineage: '' data_type: ~ date: 2007-08-30 date_type: ~ datestamp: 2008-01-07 11:57:46 department: ~ dir: disk0/00/00/00/08 divisions: [] edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 8 event_dates: 29-31 August 2007 event_location: Ouro Preto (Brazil) event_title: 10th Brasilian Symposium on Formal Methods event_type: conference exhibitors_id: [] exhibitors_name: [] fileinfo: /style/images/fileicons/application_pdf.png;/8/1/fm_sc_rs_v2.pdf full_text_status: public funders: - European Union id_number: ~ importid: ~ institution: ~ isbn: ~ ispublished: pub 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 15:05:49 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: paper producers_id: [] producers_name: [] projects: - Rodin publication: ~ publisher: ~ refereed: TRUE referencetext: ~ related_url_type: [] related_url_url: [] relation_type: [] relation_uri: [] rev_number: 31 series: ~ skill_areas: [] source: ~ status_changed: 2008-01-07 11:57:46 subjects: [] succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ task_purpose: ~ thesis_type: ~ title: Formal Methods in Safety-Critical Railway Systems type: conference_item userid: 4 volume: ~
