Grading Scale
Grading: Letter A B C D F Not higher than!
Grade 93 - 100% 84 - 92% 70 - 83% 60 - 69% <60% cIm -IE775
Papers
Papers: The papers will be of the 3-5 page variety. The papers will be 2-3 pages and the book report will be 5 pages. The paper should be 75% summary of the paper/book and 25% critique/commentary cIm -IE775
Project
The project will be accomplished with ONE or TWO other students. The project will utilize the Wonderware "In-Touch" man-machine interface software (and possibly use the "In-Control" and "IndustrialSQL Server") products if you desire)).
The project will likely be the difference between an ‘A’ and a ‘B’. The project grade will be mostly determined on the creativity and skill level shown.

Introduction
focus on the word ‘Integrated’ not on the word ‘computer’
cIm -IE775
Formal Definition
“the integration of business, engineering, manufacturing and management information that spans company functions from marketing to product distribution.” Harrington
originally, to integrate what had already been computerized.
shop floor processes manufacturing engineering planning of those processes production planning and control of both the shop floor and the materials used.

Synonyms
CIE - computer integrated enterprise CIME - computer integrated manufacturing enterprise
CIM means many different things to many different people.

CASA/SME CIM Wheel
cIm -IE775 From CASA/SME
CASA/SME CIM wheel is a good overview of CIM
revised version (quality no longer separate)
no hierarchy
which are aided by CIM?
cIm -IE775
CASA/SME CIM Wheel (background)
1985 The Computer and Automated Systems Association of the Society of Manufacturing Engineers (CASA/SME) published its vision of enterprise wide teaming--the CIM Enterprise Wheel
1992 New Manufacturing Enterprise Wheel. This updated vision preserves the understanding gained from the previous CIM Enterprise Wheel. The old Wheel looked primarily at automation and integration inside the enterprise. The new Wheel looks outside as well. It adds understanding in these six areas:
cIm -IE775
CASA/SME CIM Wheel (background)
The central role of a customer-oriented mission and vision to strive for continuous improvement.
The importance of teams and human networking in the new manufacturing environment.
The continuing importance of computer tools, now increasingly distributed and networked. This includes tools to support networking and concurrent engineering.
A focus on key processes and best practices throughout the enterprise, from marketing through design, manufacturing, and customer support.
Recognition of the move away from bureaucratic structures, to leaner and more agile organizations.
The need to integrate an understanding of the external environment, including customers, competitors, suppliers, and the global manufacturing infrastructure.
cIm -IE775
Wheel - Six Elements
The new Manufacturing Enterprise Wheel describes six fundamental elements for competitive manufacturing: The central role of the customer and evolving customer needs.
The role of people and teamwork in the organization. The revolutionary impact of shared knowledge and systems to support people and processes. Key processes from product definition through manufacturing and customer support. Enterprise resources (inputs) and responsibilities (outputs). cIm -IE775
Wheel - customer centered
A customer-centered mission provides a clear direction to align activities and empowers the work of teams in the new manufacturing enterprise.
cIm -IE775
Wheel - people
The central role of people in the organization forms the inner circle of the Wheel. The enterprise is only as strong as its people, organization, and culture. cIm -IE775

the CIM Jigsaw - what’s missing?
Computing Systems Activity Integration and Networks Software (CAD, etc.) Info and Data Implementation Manufacturing CAM cIm -IE775 Protocols and Standards
Why CIM?
because it is cool - NO!
because everyone else is -NO!
CIM is not an end, it is the means to an end
must be linked to strategy!
cIm -IE775
Why CIM - to meet competitive pressures
to reduce lead times
to reduce costs
to reduce inventory (or need for)
cIm -IE775
Why CIM - to coordinate and organize data
functional - about organization (still important)
product - about parts
operational - plan or instructions
performance - reporting on performance
cIm -IE775
Why CIM - others
to eliminate paper
automate communication
simultaneous engineering (IPD)
because it is possible?
cIm -IE775
What is INTEGRATED?
parts indistinguishable?
no, seamlessly linked is what we mean

EDI - electronic data interchange
EDI : Electronic Data Interchange (1) The subject of electronic data exchange and sharing generally, or (2) Electronic data and/or document interchange format (X12), particularly in a purchasing context. EDIF : Electronic Data Interchange Format A neutral file specification for the transfer of electronic CAD/CAM data. EDIFACT : Electronic Data Interchange for Administration, Commerce & Trade A standard for commercial transactions between (differing) computer systems of different commercial organizations.
Although we often talk of EDI applied to exchange of technical information it is properly used to describe commercial transactions such as the passing of invoices. Standards for EDI exist and are widely used. UN EDIFACT is becoming the accepted standard for this type of transaction. When technical information is exchanged between computer systems (see the item on datasheets), this is really a sub-set of technical data sharing. In these circumstances we should use the term technical EDI, or TEDI. cIm -IE775

MAP/TOP/STEP
only 15% of over 40,000 systems can communicate cost of communication is 50% of total wiring costs occur when new systems are installed or retooled custom software is needed to interface two processes programmable equipment increasing rapidly single largest roadblock to future automation of plants cIm -IE775
MAP
• • • • • • • based on Open Systems Interconnection (OSI) seven layer broadband token-bus communication spec MAP and TOP always connected, differ in applications GM has 8 plants running MAP with 25 (1990 ) GM installing MAP as they overhaul plant tests on ethernet Lotus 1-2-3 "Factory" has MAP protocols cIm -IE775
TOP
• • • • • • exchange of info in electronic mail, word processing, file transfer, graphics, database management, business analysis tools cIm -IE775
TOP objectives
• • • • • • • allow the interconnection of multiple office local-area networks (LANs), which could be connected to wide-area networks (WANs) and digital private-branch exchanges (PBXs) for long-distance communications specify existing or emerging international and industry standards make possible an office communications network in which equipment from multiple suppliers can be used facilitate free and easy data access and the interchange of data by equipment from different suppliers lower office systems costs by reducing the need for multiple cables and customized networking software improve the flexibility and adaptability of production systems to meet changing demands shorten the lead time for designing and implementing integrated office systems cIm -IE775
