5. Understanding
Downtime

6. MAJOR LOSSES

7. Planned Downtime losses
• Start-ups
• shift changes
• coffee and lunch breaks
• planned maintenance shutdowns

8. Unplanned Downtime Losses
• Equipment breakdown
• Changeovers
• Lack of material

9. Reduced Speed Losses
• Idling and minor stoppages
• Slow-downs

10. Poor Quality Losses
• Process non-conformities
• Scrap

11. TPM

12. What is Total Productive
Maintenance?
• TPM is a plant improvement
methodology which enables continuous
and rapid improvement of the
manufacturing process through use of
employee involvement, employee
empowerment, and closed-loop
measurement of results

13. • TOTAL = All encompassing by
maintenance and production
individuals working together
• PRODUCTIVE = Production goods and
services that meet or exceed
customers’ expectations
• MAINTENANCE = Keeping equipment
and plant in as good as or better than
the original conditions at all times
Breakdown of TPM

14. TPM - History
• Productive maintenance (PM) originated in
the U.S. in late 1940’s & early 1950’s
• Japanese companies modified and enhanced
it to fit the Japanese industrial
environment
• The first use the term TPM was in 1961 by
Nippondenso, a Japanese auto components
manufacturer
• Seiichi Nakajima – head of JIPM, one of
the earliest proponents, known as the
Father of TPM

15. TPM - Evolution
• Breakdown maintenance
• Preventive maintenance (PM)
• Productive maintenance
• Total productive maintenance

17. Goals of TPM
1. Aims at getting the most effective use of
equipment
2. Builds a comprehensive PM system
3. Brings together people from all departments
concerned with equipment
4. Requires the support and cooperation of
everyone from top managers down
5. Promotes and implements PM activities based
on autonomous small group activities.
6. Maintaining Equipment for life
7. Encouraging input from all employees
8. Using teams for continuous improvement

18. Three Principles of Prevention
• Maintenance of normal conditions
• Early discovery of abnormalities
• Prompt response

21. Kick off TPM

22. Launching TPM- Preparatory Stage
• Announce top management’s decision
to introduce TPM
• Launch an educational campaign to
introduce TPM
• Create an organizational structure to
promote TPM
• Establish basic policies
• Form a master plan for implementing
TPM

27. Launching TPM- Preliminary
Implementation

28. • Improve the effectiveness of each critical
piece of equipment
• Set up and implement autonomous
maintenance
• Establish a planned maintenance system in
the maintenance department
• Provide training to improve operator and
maintenance skills
• Develop an early equipment management
program
Launching TPM- TPM Implementation

29. • Perfect TPM
implementation and raise
TPM levels
Launching TPM- Stabilization

30. Eliminating Equipment Losses

31. Improvement Goals for Chronic Losses

32. OEE

33. What is OEE
• OEE (overall equipment efficiency) is
a “best practices” way to monitor and
improve the efficiency of your
manufacturing processes
– machines
– manufacturing cells
– assembly lines

34. OEE Factors
• Plant Operating Time
• Planned production time
– planned downtime ie. breaks
• Availability
– downtime losses
• Performance
– Speed losses
• Quality
– Quality losses

35. World Class OEE
OEE Factor World Class
Availability 90.0%
Performance 95.0%
Quality 99.9 %
OEE 85.0%

36. Calculating OEE
• Availability = Operating time/planned
production
• Performance = Ideal Cycle Time / Total
Pieces or
(total pieces / Operating time)/Ideal Run time
• Quality = Good Pieces / Total Pieces
• OEE = Availability X Performance X
Quality

37. Example OEE Calculation
Item Data
Shift length 8 hrs = 480 min.
Short Breaks 2@ 15 min. = 30 min
Meal Break 1 @ 30 min = 30 min
Down Time 47 min
Ideal Run Time 60 pieces per min
Total Pieces 19,271 pieces
Reject Pieces 423 pieces

38. Availability =
Operating time
Planned production time
• = 373 minutes / 420 minutes
• = 0.8881 (88.81%)

39. Performance =
(Total pieces /Operating time)
Ideal Run Time
• = (19,271 pieces/373 minutes)/60
pieces per minute
• = 0.8611 (86.11%)

40. Quality =
Good Pieces
Total Pieces
• = 18,848 / 19,271 pieces
• = 0.9780 (97.80 %)

41. OEE =
Availability X Performance X Quality
• = 0.8881 X 0.8611 X 0.9780
• = 0.7479 (74.79%)

42. TPM BENIFITS

43. TPM - Benefits
• Improved equipment eliminates the root cause of
defects
• Defects are prevented through planned
maintenance
• Preventive maintenance costs are reduced as
equipment operators conduct autonomous
maintenance
• Improved equipment designs ensure that new
equipment naturally produces fewer defects
• Simplified products designs and a redesigned
process produce with few defects
• Engineers, technicians and managers are trained in
maintenance and quality

44. TPM - Benefits
(Japanese TPM Prize winners during 1982-
1984)
• Equipment failures reduced from
1,000/month to 20/month
• Quality defects reduced from 1.0% to 0.1%
• Warranty claims reduced by 25%
• Maintenance costs reduced by 30%
• WIP decreased by 50%
• Productivity improved by 50%. (Patterson &
Fredendall, 1995)

45. TPM – Success stories
• USPS Albany, New York: annual save of
$86,000; could save $4.5 million if applied
nationwide
• Yamato Kogyo Corp., Japan:
- productivity up by 130%,
- accidents cut by 90%,
- defects reduced by 95%,
- employee suggestion rate increased by
over 300%
