Objectives
• Review the ISA 95 standards and how they are being
used in companies like Eli Lilly & Company for shop
floor to top floor integration
– The standards provide a formal model for exchanged data
between business systems and manufacturing systems
– The models also include a definition of Manufacturing
Operations Management, the activities on the shop floor that
take production schedules and perform the actual work
required to manufacture products
• The Manufacturing Operations Management models
are currently being used in the development of
multiple new manufacturing facilities
Dennis Brandl & Peter Owen

Manufacturing in the Supply Chain
• “Make” is a significant part of the supply chain and
collaborative manufacturing, but is often the last
element to be actually integrated
– Collaboration in “Make” is usually not a “Low Hanging Fruit”
– But can offer very high ROI for high volume, or high cost
products
• However, Business IT and Manufacturing IT
organizations are often at odds as they try to
collaborate
– They have different goals and different success criteria
– They use the same terms for different elements and different
terms for the same elements
Dennis Brandl & Peter Owen

Collaborative Manufacturing Help
• Fortunately there are multiple standards in
place to help integrating business systems
with manufacturing systems.
– The ISA 95 Enterprise/Control System Integration
standards, also an IEC/ISO standard
– XML Schemas standards for collaborative
manufacturing from the World Batch Forum
• Will show how they are being applied to the
development of manufacturing systems

Different Points of View
• Business Systems
– Time Horizons
• Long-term view
– Model detail
• Linear route structures
– Control emphasis
• Product cost and overall
profitability
– Modeling criteria:
• Accounting reference
points
• Has inventory value
changed significantly? If
not, don’t model
separately
– View from the boardroom
Dennis Brandl & Peter Owen
• Manufacturing Systems
– Time Horizons
• Real-time view
– Model detail
• Complex routes with
rework paths
– Control emphasis
• Physical movement &
accountability
– Modeling criteria:
• material movement
reference points
• Does product stop
moving? If not, don’t
model separately
– View from the workcenter

Philosophical Orientation
• Enterprise Management systems:
–How much is my stuff
worth?
• Manufacturing Opearations
Systems:
–Where is my stuff?

ISA 95 Provides Direction
• The ANSI/ISA 95.00.01 “Enterprise - Control
System Integration - Part 1: Models and
Terminology”
– Also Draft International Standard ISO/IEC 62264-1
• ANSI/ISA 95.00.02 “Enterprise - Control
System Integration - Part 2: Object Attributes”
• Draft ISA 95.00.03 “Enterprise - Control
System Integration - Part 3: Activity Models of
Manufacturing Operations Management”

XML Standard for B2M Exchanges
• The World Batch Forum has developed XML
Schemas that map to the ANSI/ISA-95
models
• Defines how to represent the ISA-95
information in XML
– Business To Manufacturing Markup Language
– B2MML
• One schema for each object model
• Formal way to exchange information
– www.wbf.org

Conceptual Topology – IT View
• IT View of the ISA-95 Levels and relationship to
systems and networks
• Levels 1-2
– Control the process and provide visibility to the process
– Electronic records are not embedded in the control layers
(Level 1-2)
– Usually some specialized hardware and possibly networks
• Level 3
– Maintenance of production information is centralized to
provide greater control and availability of the records
– Electronic records are managed and controlled through
Level 3 systems with audit trail, access control, backup, and
ERP connectivity
– Usually standard hardware and networks

Functional Areas
• Use the ISA 95 and ISA 88 models of functions
• Map the functions to system areas and networks
• Use the ISA 95 rules for determining what is in Level
3 (vs Level 4)
– The function is critical to maintaining regulatory compliance.
• Includes such factors as safety, cGMP, and environmental
compliance
– The function is critical to plant safety
– The function is critical to product quality
– The function is critical to plant reliability

Logical Architecture
• Maps functional areas and data locations
– Independent of technology
• Defines the different layers of the architecture in
terms of data and control
– These are mapped to physical networks, servers, and
applications in the physical architecture
• Defines what functions are to be performed at each
level, and what data is to be maintained at each level
– To result in maintainable and robust systems
– To provide a way to manage the life cycle of the production
systems
– Provides the structure required to grow and modify the
system without compromising any of the previous
advantages

Conclusions
• Linked execution systems deliver results!
– Reduced direct costs; increased productivity
– Improved traceability; reduced “witch hunt” expense
– Near-theoretical cycle times: customer responsiveness,
reduced WIP inventory
– Greater agility: smaller lot sizes, more premium products in
the mix, happier customers, happier shareholders!
• S95 defines the currency for manufacturing object
and information exchange
– Faster project implementation cycles
– Flexibility to integrate and realign as corporate structures
change

Status
• ISA95.00.01 & ISA.95.00.02 available
• IEC/ISO 62264-1 available from IEC & ISO
• ISA 95.00.03 in draft
– Still under development in the committee
• World Batch Forum
– Developed XML Schemas for the exchanged
information
• Vendors
– Many currently using ISA-95 models in
development and current products
• Users
– Specifying ISA-95 in their RFPs
