Transcript Total Productive Maintenance

Total Productive Maintenance
Dr Neil Towers
Fashion Operations Management
Learning Objectives

To understand the concept of Total
Productive Maintenance (TPM)

To be able to assess the impact of
failure for a fashion operation
Definition

“the maintenance management carried
out by all employees through small
group activities that recognises the
importance of reliability, service and
efficient operation”
Adapted from Slack et al, 3rd ed, 2001, p659
Why systems fail
Failures inside

Customer failures
How failure is detected and analysed
Failure detection mechanisms include:
- in-process checks;
- machine-diagnostic checks;
- point-of-departure interviews.
Failure analysis procedures include:
- accident investigation;
- failure mode-and-effect analysis;
- fault-tree analysis.
5 Goals of TPM





Improve equipment effectiveness
Achieve autonomous maintenance
Plan maintenance
Train all staff in relevant maintenance
skills
Achieve early equipment management
Recovery strategies for dealing with failure
Plan
Failure analysis - possibilities
Recovery planning - procedures
Discover
The facts - what has happened?
The consequences
Act
Learn
Inform, contain and follow up
Find the root cause
Prevent it happening again

Fashion Operations issues

Extended geographic supply chains
– Long distances
– High transit times

Multiple intermediaries
– Agents, Wholesalers, Logistics operators
Customer Service

Intensive selling season
– Compressed timescale

High customer expectations
– Focus on satisfaction
