--- abstract: 'In this short paper we describe early work on a case study concerning a power window control unit. We use UML-B state machines to simultaneously model both the cyclic processing schedule and the mode of control behaviour. We find this a useful way to visualise the model, particularly when the state machines are animated via the Pro-B animator. We verify the state machines using the Event-B proof tools. We envisage new developments to the UML-B tool set to improve support for this modelling technique. The motivation for this simple but powerful form of modelling is the immediate benefit and low cost of entry making industrial adoption of formal models more attractive to industry.' accompaniment: [] book_title: ~ commentary: ~ completion_time: ~ composition_type: ~ conductors_id: [] conductors_name: [] contact_email: ~ copyright_holders: [] corp_creators: [] creators_id: [] creators_name: - family: Snook given: Colin honourific: '' lineage: '' data_type: ~ date: 2011-06 date_type: published datestamp: 2012-07-23 09:55:11 department: ~ dir: disk0/00/00/04/29 divisions: [] edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 429 event_dates: ~ event_location: ~ event_title: B2011 event_type: workshop exhibitors_id: [] exhibitors_name: [] fileinfo: ~ full_text_status: none funders: [] id_number: ~ importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: ~ 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: 2012-07-23 09:55:11 latitude: ~ learning_level: ~ longitude: ~ lyricists_id: [] lyricists_name: [] metadata_visibility: show monograph_type: ~ note: ' Event Dates: 21st June 2011' num_pieces: ~ number: ~ official_url: http://eprints.soton.ac.uk/272287/ output_media: ~ pagerange: ~ pages: ~ patent_applicant: ~ pedagogic_type: ~ place_of_pub: ~ pres_type: paper producers_id: [] producers_name: [] projects: [] publication: ~ publisher: ~ refereed: TRUE referencetext: ~ related_url_type: [] related_url_url: [] relation_type: [] relation_uri: [] rev_number: 8 series: ~ skill_areas: [] source: ~ status_changed: 2012-07-23 09:55:11 subjects: - Refinement - deploy_method_other - deploy_method_reqevo succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ task_purpose: ~ thesis_type: ~ title: Modelling Control Process and Control Mode with Synchronising Orthogonal State Machines type: conference_item userid: 258 volume: ~
