Concepts in Connecting the Manufacturing Environment

Concepts in Connecting the Manufacturing
Environment

• A pile of bricks is not a Building
• How to convey the message that information
  architecture is vital.
• Divide and Conquer but how ?
• PERA Model
• Disciplines
• Logical (S/W) and Physical (H/W)
• Other ways possible but arcane (CIMOSA Views)
• Structure must follow organizational
  responsibility
• Standards may eliminate need to understand and
  model every element.
• Role of Standards
• Every CIM system custom ?
• Doors, windows, etc. (see PERA FAQ Why
  Standards)
• Must define Modules (generic and
  industry-specific)

Why Has It Taken So Long to Get Connected?

• Why has it taken so long to get information
  flowing to and from the shop floor and
  horizontally between shop floor systems?
• Technical difficulty
• Human
• Resistance to change (all levels)
• Poses threat to middle management
• High entry cost
• Because is custom built from proprietary
  standards (or no standards) only affordable by
  biggest and richest
• Lack of Continuity of Vision
• If successful, originating manager is promoted
• If unsuccessful, originating manager is
  eliminated

Enterprise Architecture
4
Possible Messages from Architecture Design
Developments

• Application of 4R principles can improve
  integrity and flexibility of Enterprise
  Architecture Designs.
• Application of engineering integration
  documentation and methods can improve interface
  with engineering, construction and enterprise
  management.
• Need for defined set of Control and Information
  System Drawings and Specification Documents
• Enterprise Architecture Diagram serves like PID
• Other SI documents parallel Control Systems
• XML seems to be vehicle of choice for
  implementing system interfaces (merge with
  Ariba-style interface strategy between
  enterprises ?).
• Telecom is becoming a larger part of enterprise
  integration (VPNs, TCP/IP, VoIP, higher network
  integrity).
• Need training materials for employees ?
• Eg. Ethernet-TCP/IP design for Control Engineers

Role of Enterprise System Standards

• Major standards groups are undertaking enterprise
  systems initiatives
• ISA (S95, S88)
• ISO (TC 184/SC5, CIMOSA, STEP)
• IEC
• IFAC/IFIP
• PERA has been involved with all of the above, and
  many have direct PERA content.
• Directions from S95 meetings and ISO meetings at
  NIST in Washington
• Plan for coordination of standards between ISA
  (previously primarily continuous and batch), and
  ISO/CEN (previously primarily discrete).
• Ultimately will develop standards which can be
  attached to RFPs.

Possible Messages from Enterprise Standards
Developments

• Open standards will change the way MES systems
  are delivered and interfaced, for example
• S95 will define modularity and data constructs
  for exchange of plant information. Software
  products will conform to these standards.
• Specialized system vendors will be able to better
  compete (and integrate) with All-in-One
  vendors.
• Ariba collaborative system model will displace
  SAP proprietary model.
• Cost of system purchase, integration, and support
  will diminish
• If US and European standards are coordinated, the
  playing field for international systems
  integration products and services will change.
• Increased opportunity for centers of excellence
  which serve a world-wide client base.
• Industry participation in emerging standards
  groups (ISA, ISO, IEC) ?

Lessons from Russian Mega-Project

• Engineering of large enterprises will soon be
  totally web-centric
• Engineering systems and communications
  (particularly for frontier projects) should be
  designed to roll forward into operations phase.
• Ethernet TCP/IP will increasingly be used at all
  levels in Industrial Enterprise Architectures.
• Web server technology will move to plant
  supervisory systems and even smart sensors.
• Coordination of CIS design with engineering
  brings large paybacks.
• Merging of Enterprise Voice and Data
  communications (Voice over IP) brings 50
  savings.
• Education of Enterprise and Project Management is
  crucial to success.
• Skilled, cost-effective IT resources are widely
  available in Russia and other off-shore
  locations.
• Draft Caspian Pipeline PERA application paper
  approved for publication.
