The document discusses the components of Overall Equipment Effectiveness (OEE) - availability, performance, and quality. It analyzes how reliability, in the form of the bathtub curve, applies to each component. For availability, improvements include trial runs, operator training, and robust maintenance. For performance, improvements involve trial runs and maintenance. For quality, improvements are feasibility analysis, product/process FMEAs, and maintenance. The document will continue the analysis.

Reliability bathtub curve applied to the OEE measurable components

2. OEE definition
iper – Industrial Performance 2015-01-19 joao.leite@iper.pt
OEE - Overall equipment effectiveness
OEE breaks the performance of a manufacturing unit into three separate
but measurable components:
 Availability
Availability = uptime/ available time
 Performance
Performance = (Parts Produced * Ideal Cycle Time) / Operating time
 Quality
Quality = (Units produced - defective units) / (Units produced)

3. Reliability applied to the Availability
iper – Industrial Performance 2015-01-19 joao.leite@iper.pt
How to improve:
- Sample productions
prior to start of the
serial production
( TRIAL RUNS )
- Operators training
How to improve:
- Implementation of a
robust maintenance plan
- Machine FMEA
