The specifications for a power unit consisting of 3 independent and serially related components (failure modes) require a design life of 5 years with a 0.95 reliability
- Let each component have a constant failure rate such that the first component’s rate is twice that of the second and the third components rate is three times that of the second. What should be the MTTF of each component and the system?
- If two identical power units are placed in parallel, what is the system reliability at 5yr, and what is the system MTTF?

Within the heat treatment system there are 10 steps with independent failure modes. Each of them has a constant failure rate CFR hazard ?????. If a design life of 7 years with a reliability of 0.92 is required, what should the system MTTF and median time to failure be and what will be the ???? for a given mode of failure?

module, consists of five repairable components, all of which must operate for system success. Each component performs a different function but all five share identical reliability parameters. Specifically, MTTF for each component is 100 years and MTTR 40 hours. Calculate the following for this single system module: 1) Failure rate 2) Average down time 3) Unavailability

Problem 3: Consider a series structure of 10 independent and identical components Each component has an MTTF 5000 hours. a) Determine MTTtm when the components have constant failure rates. (b) Assume next that the life lengths of the components are Weibull distributed with shape parameter a 0.2. Determine MTTFsystem and compare with (a). (c) Assume now that you have a parallel structure of two independent and identical components with MTTF 5000 hours. Repeat problem (a).
