4. Definition of CIM by the Computer and Automation
Systems Association of the Society of
manufacturing Engineers (CASA/SME):
“CIM is the integration of the
total manufacturing enterprise
through the use of integrated
systems and data
communications coupled with
new managerial philosophies
that improve organizational and
personnel efficiency.”

5. CIM

6. What is CIM?
CIM is the integration of all enterprise
operations and activities around a common
corporate data repository.
It is the use of integrated systems and
data communications coupled with new
managerial philosophies.

7. What is CIM?
CIM is not a product that can be
purchased and installed.
It is a way of thinking and solving
problems.

8. POTANTIAL BENEFITS OF CIM
 Improved customer service
 Improved quality
 Shorter time to market with new products
 Shorter flow time
 Shorter vendor lead time
 Reduced inventory levels
 Improved schedule performance
 Greater flexibility and responsiveness
 Improved competitiveness
 Lower total cost
 Shorter customer lead time
 Increase in manufacturing productivity
 Decrease in work-in process inventory

9. The Role of Computer in
Manufacturing
The computer has had a substantial
impact on almost all activities of a factory.
Often, the introduction of the computer
changed the organizational structure of a
department and made necessary adoption
of new management structures.

10. The Role of Computer in
Manufacturing
The operation of a CIM system gives
the user substantial benefits:
• Reduction of design costs by 15-30%;
• Reduction of the in-shop time of a part by
30-60%;
• Increase of productivity by 40-70%;
• Better product quality, reduction of scrap
20-50%.

11. AGILE MANUFACTURING
 Globalization of markets has put
tremendous pressure on
manufacturing enterprises to be
competitive.
 To cope with competitive pressures,
a new paradigm in manufacturing
known as AGILE MANUFACTURING is
emerging.

12. AGILE MANUFACTURING
The objective of agile
manufacturing is to enable
manufacturing enterprises to be
competitive by dynamically
reconfiguring software, equipment
and organization structures.

13. AGILE MANUFACTURING
Agility is the ability to grow and
succeed in an environment of
constant and unpredictable changes.
In recent years, the manufacturing
paradigm has been changing from
mass production to agile
manufacturing.

14. AGILE MANUFACTURING
The reasons of this trend change are:
• The strength of global competition is
increasing;
• Mass markets are fragmenting to niche
markets;
• Customers expect low volume, high
quality;
• Short product life-cycles, development

15. CHARACTERISTICS OF AGILE
MANUFACTURING:
 Greater product customization
 Rapid introduction of new or modified
product
 Advanced interenterpise networking
technology
 Upgradable products
 Increased emphasis on knowledgeable,
highly trained workers
 Interactive customer relationship

16. CHARACTERISTICS OF AGILE
MANUFACTURING:
 Dynamic reconfiguration of production
processes
 Greater use of flexible production
technologies
 Rapid prototyping
 An open systems information environment
 Innovative and flexible management
structures
 Product pricing based on value to the
customer
 Commitment to the bening operations and
product designs

17. Communication Networks
A communication network is the backbone of
an enterprise integration. Networks help to unify
a company by linking together all the
computerized devices irrespective of their
physical location.
Through networks the whole enterprise can be
integrated, including suppliers and customers.

18. Communication Networks
For example, sales and marketing can send
customer requirements for new products to
design engineering.
A CAD generated bill of materials can then be
transferred to “material requirements
planning(MRP)” systems.
Product design information can be transmitted
to manufacturing for use in process planning.

19. Types of Communication
Networks
There 2 main types of
communication networks:
1) Telecommunication Networks;
2) Computer communication Networks.

20. Types of Communication
Networks
Telecommunication network is mainly used
for voice communication.
Computer communication network is a
system of interconnected computers and
other devices capable exchanging
information.

21. Highlights in the History of
Telecommunications
1844 Morse sends the first public telegraph
message
1876 Telephone patent issued to Alexander
Graham Bell
1877 First telephone in private home
1881 First long-distance line, from Boston, MA, to
Providence,RI
1890 Undersea telephone cable, England to France

23. Types of Communication
Networks
Network Architectures & Protocols
A communication network consists of a number
components such as hardware, software and
media.
A network architecture describes the components,
the functions performed, and the interfaces
between the components of a network.
It encompasses hardware, software, standards,
data link controls, topologies and protocols.

24. Types of Communication
Networks
Network Architectures & Protocols
It defines the functions of, and interactions
between, three types of components.
 Network hardware components
 Communication software modules
 Application programs that use the networks

25. Types of Communication
Networks
Network Architectures & Protocols
PROTOCOL:
Protocols in network architecture define the set of
rules of information exchange between two
devices(peers).
Protocols specify the message format and the
rules for interpreting and reacting to messages.

26. Types of Communication
Networks
Computer Network Reference Model
The OSI (Open Systems Interconnection)
Reference Model is an architecture that
enables different vendors’ systems, such
as DECNET, SNA, TCP/IP and SINEC, to
communicate by using a common set of
protocols.

27. Types of Communication
Networks
The reference model is based on:
• The communication functions are divided into
layers;
• The services to be provided by each layer are
specified;
• Layer N+1, above layer N, uses the services of
the latter to implement its functions;
• Communication between the layer N and the
participating terminals is specified by the ISO
protocols.

28. Types of Communication
Networks

29. TYPES OF COMPUTER NETWORKS
Local Area Networks (LANs)
Used to interconnect computers
within the same building or
organisation.
A LAN typically operates at speeds
ranging from 10 Mbps to 100 Mbps,
connecting several hundred devices
over a distance of up to 5 to 10 km

31. Metropolitan Area Networks (MANs) - MANs are large
LANs that cover a large city or suburb. Used to
interconnect LANs within a metropolitan area. A typical
MAN operates at a speed of 1,5 to 150 Mbps

32. Wide Area Networks (WANs)
Use common carrier facilities over
long distances and are used to
connect sites and facilities over the
countries.
Usually the speed between the cities
can vary from 1.5 Mbps to 2.4 Gbps.
In a WAN, the cost of transmission is
very high, and the network is usually
owned and operated by a public
network

33. Global Area Networks (GAN)
these are networks connections
between countries around the globe.
A GAN’s speed ranges from
1.5Mbps to 100Gbps and its reach is
several thousands of kilometres.

35. COMMUNICATION HIERARCHY
 enterprise level
Globally link various plants/sites and
interconnect corporations through electronic
data interchange
 plant level
Connect departments inside plant
 cell level
Connect cells inside departments
 equipment/device level
connect individual devices such as computers,
robots and NC machines

36. MANUFACTURING
 Parallel with increasing needs for faster
communications the needs of large data storage
capacity and fast computers is increasing also.
 Now typical manufacturing environment, called
also as CAD/CAM/CAE environment is composed
of fast computers, centralized data storage units,
CNC controlled machine centers, robots etc., all
connected on the same network.
 On this networks either TCP/IP or specially
designed manufacturing protocols like, MAP or
TOP, are used.

37. MANUFACTURING
MAP
An initiative by General Motors of The
United States has resulted in the selection
of a set of protocols, all based on ISO
standards, to achieve open system
interconnection within an automated
manufacturing plant.
The resulting protocols are knows as
manufacturing automation protocols
(MAPs).

38. MANUFACTURING

39. MANUFACTURING
TOP
In a similar way, an initiative by the
Boeing Corporation (USA) has resulted in
the selection of a set of ISO standards to
achieve open system interconnection in a
technical and office environment.
The selected protocols are known as
technical and office protocols (TOPs).
