Question

Consider a sound system with logic and single-hour listening reliability as given in Figure 6-13. Find the system reliability using the reliabilities given below.

Power Supply Reliability: 0.995
Amplifier Reliability: 0.995
CD Player Reliability: 0.980
Tuner Reliability: 0.985
Tape Deck Reliability: 0.990
Turntable Reliability: 0.985
Each Speaker Reliability: 0.960

System Relibility= ?

Answer 1

answer:

given data,

Power Supply Reliability: 0.995
Amplifier Reliability: 0.995
CD Player Reliability: 0.980
Tuner Reliability: 0.985
Tape Deck Reliability: 0.990
Turntable Reliability: 0.985
Each Speaker Reliability: 0.960

• now we are need the find the relibility
• here we haved the, system reliability is, we have the formula Is

=(Power Supply Reliability*Amplifier Reliability*CD Player Reliability:*Tuner Reliability*Tape Deck Reliability*Turntable Reliability*Each Speaker Reliability

• now substitute the values in the fornula

=0.995*0.995*0980*0.985*0.990*0.985*0.960

=0.8946

so finally the system relibility is

0.8946
