Introduction

• Lack of production efficiency
• Implementation of JIT
• Looking into implementing CIM

3
What is CIM?? 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
(CASA/SME 1990)

• CIM CAD CAM MIS
• Computer Aided Design (CAD) Design of
  products through the use of computer software.
• Computer Aided Manufacturing (CAM) Use of
  computers to plan, manage and control operations
  of a manufacturing plant.
• Management Information System (MIS) Monitoring
  performance, maintaining coordination, provides
  background information about operations, used by
  employees and management.

5

• Advantages of CIM
• Higher quality output computer aided quality
  control
• Lower cost of production computers more
  efficient and less raw material waste
• Greater flexibility CAD and CAM integration

6

• Advantages of CIM
• Competitive world wide
• Translates into higher earnings for the company
• Improved customer service
• Quicker time-to market with new products

7

• Disadvantages of CIM
• Enormous cost and time consumption associated
  with research/planning
• Implementation costs are huge hardware,
  software and assembly line equipment
• Training of employees
• Employee job security fears

8

• Implementation of CIM
• Integrate Information Systems with all FAGs
• Automate Engineering with CAD. Automate
  Manufacturing with CAM. Connect the two.
• Sales, purchasing, shipping and receiving,
  manufacturing all sharing the same information
  through MIS

9

• Risks Involved With CIM
• Too much money spent on research BUT not enough
  available for implementation
• Employee inertia (resistance to change)
• Risk of costly downtime if implementation fails

10

• Conclusion
• Do the benefits outweigh the costs?
• Are we able to implement CIM?
• Are we ready to take on this challenge?
