Enterprise-manufacturing systems integration requires a methodology to maintain overall life cycle of production system PERA can be a possible solution Tools and standardized data interchange formats are required to support the use of the methodology ISA-95 & B2MML are suitable implementations

4. Motivation
Integrate business level
with factory floor
•How to get a model in
a systemized way?
•What standards/tools
map to that model?
•Towards integration

5. CIM Computer Integrated
Manufacturing
• Computer automated system to organize
and link high level and low level
information/functions:
– design, analysis, planning, purchasing, cost
accounting, inventory control, and distribution
– Material handling, actuators control and
monitoring
17.01.13 5

6. Enterprise Modelling
• Abstract representation of resources in an
enterprise.
– Description
– Definition
– Relations
– Structure
– Processes
• Models needed for:
– Decision taking, integration
17.01.13 6

7. GERAM—Generalised Enterprise
Reference Architecture and
Methodology
• Tool used for enterprise modelling
• Developed in 1990s by IFAC/IFIP Task Force
on Architectures for Enterprise Integration
• Collects frameworks for enterprise integration
and provides a generic version

8. GERAM framework components

9. PERA, Purdue Enterprise Reference
Architecture
• PERA is a GERAM, a Generalized Enterprise
Reference Architectural Model.
• Represents an enterprise system as a model
• Designed for Process, Manufacturing and
Services Industries
• Goes through the full life cycle of the system.
• Facilitates decisions in planning, integration
• Proposed to be an international standard

10. PERA components
• Main components in an
enterprise:
– Physical plant (facilities)
– People
– Control and information
systems

13. ISA-95
• Interfaces between business and factory floor
• Boost integration between ERP and MES
• For all industries: batch, continuous, discrete
• Consistent terminology
• Defines levels, functions, information flow, data
models.

14. ISA-95 levels
17.01.13 14

15. ISA-95: Exchanged
information and data models
• Defines information exchanged
between level 4 and level 3
• Provides data models
• UML class diagrams notation
17.01.13 15

16. B2MLL Business To
Manufacturing Markup
Language
• Implementation of ISA-95
• XML Schema Definition (xsd)

22. Conclusions
• Enterprise-manufacturing systems integration requires a
methodology to maintain overall life cycle of production
system
PERA can be a possible solution
• Tools and standardized data interchange formats are
required to support the use of the methodology
ISA-95 & B2MML are suitable implementations
