--- abstract: "This paper describes a case study involving the reconfiguration of an office workflow. We state the requirements on a system implementing the workflow and its reconfiguration, and describe the system’s design in BPMN. We then use an asynchronous pi-calculus and Webpi to model the design and to verify whether or not it will meet\r\nthe requirements. In the process, we evaluate the formalisms for their suitability for the modelling and analysis of dynamic reconfiguration of dependable systems." accompaniment: [] book_title: ~ commentary: ~ completion_time: ~ composition_type: ~ conductors_id: [] conductors_name: [] contact_email: ~ copyright_holders: [] corp_creators: [] creators_id: - manuel.mazzara@newcastle.ac.uk creators_name: - family: Mazzara given: Manuel honourific: '' lineage: '' data_type: ~ date: ~ date_type: ~ datestamp: 2011-06-28 10:07:11 department: ~ dir: disk0/00/00/03/13 divisions: [] edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 313 event_dates: ~ event_location: ~ event_title: PNSE’11 – Petri Nets and Software Engineering event_type: workshop exhibitors_id: [] exhibitors_name: [] fileinfo: /style/images/fileicons/application_pdf.png;/313/1/PNSE2011.pdf full_text_status: public funders: [] 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: 2011-06-28 10:07:11 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: keynote producers_id: [] producers_name: [] projects: [] publication: ~ publisher: ~ refereed: TRUE referencetext: ~ related_url_type: [] related_url_url: [] relation_type: [] relation_uri: [] rev_number: 23 series: ~ skill_areas: [] source: ~ status_changed: 2011-06-28 10:07:11 subjects: - deploy_method_proof - deploy_method_reqevo - deploy_method_resil succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ task_purpose: ~ thesis_type: ~ title: 'Design, Modelling and Analysis of a Workflow Reconfiguration' type: conference_item userid: 217 volume: ~
