TECH SPOT: SAMPLE CRE QUESTIONS (Part 31)

By Tim Gaens posted 14 days ago
1.Assume you have three equal units that operate together as parallel units. The failure rate of each unit is λ=0.01. The reliability of a single unit for a 10-hour operation is R=e-0.1=0.90484 or ~90%.. How much can we improve the reliability by operating these three units in parallel? A .0.98885 B. 0.999138 C. .990575 D. 0.99991 The unreliability of a single unit for t=10 hrs is Q=1-R=1-0.90484=0.09516 . The unreliability of the parallel group is Q parallel =Q 3 =(0.09516) 3 =0.000862 The reliability of the parallel group of the three units f or a 10 Hr operation is: R parallel = =1- Q ...
