Consider System Following Given Conditions Failure Rate 0002 Total Operating Time 20 000 H Q34316284

Consider a system with the following given conditions:

Failure rate = .0002

Total Operating time = 20,000 hours

Mean Down Time = 60 hours

Total number of Maintenance actions = 40

Mean preventive maintenance Time = 6 hours

Mean Logistics plus administrative time = 20 hours

Calculate a) MTBF, b) MTBM, c)Average M, d) MTTR, e) fpt(preventive maintenance frequency factor) and f) Mct and g) allavailability measures for Commercial applications (Aa, Ao andAi)

Expert Answer

1. MTBF=Is basically inverse of failure rate =1/0.0002=5000

2. MTBM is given by ratio of total operating time and totalnumber of maintenance action taken =20000/40=500

3.Average is equal to difference between mean downtime and meanlogistics
