1. ENTERPRISE MODEL FOR INTEGRATING PROCESS CONTROL INTO CAM SYSTEMS Samuel BASSETTO, Ali SIADAT, François VERNADAT, Patrick MARTIN

2. 1 2 3 4 ENTERPRISE MODEL FOR INTEGRATING PROCESS CONTROL INTO CAM SYSTEMS • Position of process control, need for integration • How we infer business process… • Model proposed • Enterprise model of process control reuse during projects OUTLINE

3. 1 2 3 4 Several Point of view for« process control » • Process Control @ Organizational level • Change Mgt, Risk Mgt, DOE, (Pinaton, 2004) • Organizational FeedBack (Zur Muehlen, 2005) • Process Control @ Manufacturing level • SPC (Montgomery, 2001) • 3 level Architecture process control (Sachs, 1991) • Process Control @ Tool level • Tool regulation (Corriou, 1996) • R2R Ctrl (Zamaï, 1997) • Fault Detection And Classification (Van Herk, 1999) Needs for integration

4. 1 2 3 4 Complexity of process control Process control system Change mangement Indicators Risk analysis Investigations Statistical Control Automation & measures Need for integration Product Complex interactions Manufacturing process Means Status : • No clear view • Interactions explicited case after case, like scenarii • No link between Control @ orga level, @ process level, @ tool level

5. Consequences 1 2 3 4  It is easy to : • Drive with poles of expertises • Structure and monitor manufacturing processes • Be Reactive • Computer base support for experts Need for integration  It is not so easy to : • Have a global picture of activities • Support : • Activities interactions • Take care of system evolution • Be Proactive • Lack of integration • Strong IT supplier dependance

6. Our method 1 2 3 4 Use enterprise modelling to : • Furnish a global picture (activities, BP, Data) • Help methods convergences in redefining activities scope • Understand interactions between activities • Drive application with a development path : From AS-IS to TO-BE Need for integration

8. 1 2 3 4 Some process control process (1/2) Tool risk management Customer claims management Customer reclaim Tool unschedule event Event recording Customer Claims recording X-Site Tool Business process modelling Maintenance analysis and action procedure R000770 Customer claim off line analysis Specific maintenance program Investigations Investigations Synthesis Synthesis Action plan Action plan Tool C2_Report Identification of risked areas Major detractors identification

9. 1 2 3 4 Some process control process (2/2) Non conformities management Change management Non conformities (<4% of the WIP) Changes (2, 3 per week) Non conformity recording SCRAP Form Demand of change record Procédure ECN Business process modelling Off line analysis of non conformance Off line analysis of change’s impacts 8D process Procédure PCRB Investigations Investigations Synthesis Synthesis Action plan Intranet Action plan Major detractor Intranet PCRB Minutes

10. 1 2 3 4 From many processes to a business process Need for investigate Event Event collect & record Define the control plan Loop until the data collection is satisfying Event off line analysis Business process modelling Investigations Collect Synthesis Off line analyse Action plan Informations on off line analysis Results of investigation

11. 1 2 3 4 ENTERPRISE MODEL FOR INTEGRATING PROCESS CONTROL INTO CAM SYSTEMS  Position of process control, need for integration  How we infer business process… • Model proposed • Enterprise model of process control reuse during project OUTLINE

12. 1 2 3 4 Process control activities Control plan, capability Data collected, collected event, explicit informations Data, event, implicit information Collect Tools and methods Analysis methods Control plan, analysis results, action plan Analysis needs, collected data Analyse off line Tools, methods, experts The model proposed Analysis methods Level of master, action plan Analyse on line Collected data Tools, methods, experts Call / Analysis need Synthesis rules Information on current activity behavior Synthesis Other activities outputs Tools

13. 1 2 3 4 Process control data model The model proposed

14. 1 2 3 4 Process control data model The model proposed

15. 1 2 3 4 Process control data model The model proposed

16. 1 2 3 4 Links between activities • Activities interelation (and not sequential view) The model proposed

17. 1 2 3 4 Two business processes • Sequential view of activities The model proposed

18. 1 2 3 4 Synthesis • VISION for process control (TO-BE model ) • 4 activities et 2 associated Business Process • functionnal & temporal view separation • Distinction between functions – means – contraintes – flows • Master information flows: The model proposed Complex interactions NOT Mastered Complex interactions Mastered and tooled

19. 1 2 3 4 ENTERPRISE MODEL FOR INTEGRATING PROCESS CONTROL INTO CAM SYSTEMS  Position of process control, need for integration  How we infer business process…  Model proposed • Enterprise model of process control reuse during project OUTLINE

20. 1 2 3 4 Application case (1/2) • Computer base application development for business process BP1 : Computer supported off line analysis Model reuse

21. 1 2 3 4 Application case (2/2) • Computer base application development for business process BP2 : automatic online analysis Model reuse

22. Conclusion • Proposition of a process control model • 4 activities : Collect, Analyse off line, Analyse on line, Synthesis • At least 2 business processes • 2 industrial applications • This model contributes at information system bricks convergence toward business requirements. Integration : the red line of our presentation Conclusion & discussions
