Presentation Transcript

  1. Richard A. Wysk IE551 - Computer Control of Manufacturing Systems • Architectures for Manufacturing

  2. Agenda • Types of manufacturing architectures • Architectural linkages • Integration/hooks

  3. Introduction • What is an Architecture? • “a style or method of design and construction” • “a design or orderly arrangement perceived by man” • Why are architectures important? • Relevant for CIM control

  4. Types of Architectures • Different architectures in a manufacturing • facility • Physical • Logical • Organizational

  5. The Physical Layout • Adjacency • Floor space utilization • Accessibility • Flexibility

  6. Integrated CIM Cell

  7. Unit D Horizon V Vertical Mill Kardex AS/RS Bridgeport CNC Mill Rotational Machining Workstation Storage Workstation Material Transport Cart Part Inverter Daewoo Puma Turning Center IBM 7535 Material Transport Cart Prismatic Machining Workstation Buffer Faunc M1-L Material Transport Cart Assembly Workstation Material Transport Cart Fanuc A0 Cartrac Unit Conveyor Transport System IBM 7545

  8. Functional Architecture • How tasks relate to each other • Sales • Marketing • Order entry • Production control • Process planning • Etc.

  9. Communication Architecture • Linkages between entities that allow for • the transmission of information • Physical layer • Protocols and packeting of information • See Chapter 6 of Chang et al

  10. Information System Architecture • Data repositiories • Access method (DMA, TCP/IP, etc.) • Assess protocol (SQL, ODBC, fixed read, etc.) • Ownership/privilege

  11. Example DHS - Data Handler Server DHC - Data Handler Client DHC DHC DHC DHS DHC ... ... DHC Database Controller

  12. Control Architecture • Considers all other architectures • Organization architecture • Responsibility • Ownership • Functions

  13. A Controller Planning Scheduling Execution

  14. An Equipment Controller Equipment process plan (e.g. CAD file) Data Handler Equipment Controller Convert Device specific data (e.g. NC file, CL data, etc.) Machine Controller Individual spindle/joint activation commands Physical Machine

  15. A Collection of Controllers Equip Equip Equip Equip Equip Equip Shop Resource Manager Wkstn Wkstn Wkstn

  16. Control Architecture • Hierarchical control (Master/Slave) • Decomposition of functions into a tree structure • Logical layers of control • Heterarchical control • Democracy at work • Cooperative control • Several specifications of both • ICAM 7 layer hierarchy • NIST hierarchy

  17. What do we need to know? • Computer control • Communications • Functional control • Information access and processing

  18. Where we go from here? • Overview of architectures • Functional architectures • Information architectures • Communication architectures • RapidCIM • Simulation-based Control • Holonic Manufacturing
