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

Slide 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 its a fault but not a failure.

Slide 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.

Slide 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

Slide 13

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

Slide 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

Slide 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.

Slide 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.

Slide 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 18
