Week 12 - Reliability Flashcards
1
Q
Reliability definition
A
The probability that a component or system will function properly
2
Q
Reliability assumptions
A
- assume components are independent
- no partial failures
- known reliabilities per component
3
Q
Series Systems
A
- they system survives only if all components survive
- modelled by or gate
4
Q
Parallel systems
A
- Reliability is the chance that not all components fail
- modelled by and gate
5
Q
Reliability Importance (RIa)
A
∂R/ ∂ra - sensitivity analysis
- ∂R is the reliability of entire system
