The document discusses the use of computers in industrial engineering. It describes how computers can be used for tasks like material requirements planning, manufacturing resource planning, just-in-time manufacturing, computer-aided design, computer-aided manufacturing, robotics, and flexible manufacturing systems. It also discusses the development of integrated systems that combine CAD/CAM, computer-aided process planning, and computer-integrated manufacturing. The document provides an example of how automation and computerization at a piston pin factory increased production from 1400 pins per hour to 4200 pins per hour using fewer machines and less skilled workers.
2. INTRODUCTION
• WHAT ARE COMPUTERS?
• WHAT CAN COMPUTERS DO?
• WHERE CAN THEY BE USED?
• WHO CAN USE A COMPUTER?
3. INTRODUCTION
• an electronic device which is capable of
receiving information (data) in a particular
form and of performing a sequence of
operations in accordance with a
predetermined but variable set of procedural
instructions (program) to produce a result in
the form of information or signals.
4. NEED OF COMPUTERS IN INDUSTRIAL
ENGINEERING
CARACTERISTICS OF COMPUTERS:
1. SPEED
2. ACCURACY
3. STORAGE
4. VERSATILITY
5. AUTOMATION
6. DILIGENCE
5. NEED OF COMPUTERS IN INDUSTRIAL
ENGINEERING
• INCREASE IN QUALITY EXPECTATION OF
CUSTOMERS

9. Development of Integrated Systems
• System Integration is defined as the process
of bringing together the component
subsystems into one system and ensuring that
the subsystems function together as a system.

12. Information & Management Systems &
Industrial Statistics
Industrial statistics measure a variety of
different characteristics about various sectors
• Employment
• Turnover – Balance sheets
• Value added
• Volume of production
13. Advantages of Integrated Systems
• Fewer lost and mislabelled samples
• Clearer visualization of relationships between
samples and experiments
• Reduction of experimental error
• More effective search
• Higher quality analysis
• Productivity gains – orderly organized
• Improved archiving – storing data
• Sustainability - freezers
Benefits of integrated management of samples and
experimental data
15. CASE STUDY
• CONDUCTED BY MIKE KUTCHER- CHAIRMAN OF IBMs
CORPORATE AUTOMATIONS COUNCIL
• STUDY ON INCREASE IN PRODUCTIVITY DUE TO
AUTOMATION
• TRADITIONAL DEFINITION- OUTPUT PER HOUR
16. PISTON PINS
• JOINS PISTON TO THE CONNECTING ROD
• REQUIRES HIGH PRECISION
30 years ago NOW
1400 per hour 4200 per hour
8 machines 3 machines
3 skilled operators 1 operator with moderate skill
1 inspector None needed
17. The difference
• Lesser Machines
• Less skilled workforce
• Less floor space
• More reliable, uptime is 90%
• Higher quality products
• Tolerances can be maintained
• Inspection is automated.
• Less physical and mental effort.
