9. KEY CONCEPTS OF RQM RELIABILITY
Reliability, in its simplest form, means that a failure may not occur in a given time interval .
Reliability emphasizes on four elements:
1) Probability,
2) Intended Function,
3) Time
4) Operating Conditions

10. FAILURES • Fault: anything that has gone wrong
• Failure: an equipment problem
• All failures are faults
• Examples: If a transport system stops due to
– particles that are normal to the process, then it is a failure (and a fault).
– a left wrench inside, then it’s a fault but not a failure.

11. MAINTAINABILITY
Maintainability can be defined as the probability that failed equipment is restored to operable conditions in a specified time i.e. down time .

12. AVAILABILITY
The steady state availability is defined as the proportion of time during which equipment is available for use.
Availability = Uptime \ Uptime + down time

13. Probability
Probability= Total no. of ways event can occur/Total no. of possible outcomes

14. Random Variables

Also watch--

15. SYSTEM RELIABILITY Reliability of Systems in series
Reliability of Systems in parallel
Reliability of Systems in series-parallel
Reliability of Non series-parallel systems

16. ELECTRONIC COMPONENTS RELIABILITY
Electronic components can be caused to fail by fatigue, creep, wear, corrosion along with electrical & thermal stresses.
Reliability of well-designed, well-manufactured electronic systems is extremely high, & there are no practical limits to the reliability that can be achieved with reasonable care & expenditure .

17. CIRCUIT & SYSTEM ASPECTS
Distortion,Jitter,Timing,Electromagnetic interference are some of the circuit & system aspects.
Also,a large proportion of the failures of modern electronic system are of intermittent nature.

18. KEY RESEARCH AREA OF DIGITAL COMMUNICATION
Research areas in cluster of DC:
Fast Multiple Access more than the speed of light.
To reduce the complexity & cost of Receiver & Transmitter used in DC components.
To reduce the noise to a zero level
Efficient long range communications
To increase the Channel Capacity
