System Operating Time 10 000 Hours Mtbf 250 Hours Corrective Maintenance Two Technicians A Q34256231

A system has an operating time of 10,000 hours. Its MTBF is 250hours. For each corrective maintenance, two technicians have beenassigned. The Mean Corrective Maintenance Time is 2 hours. a)Calculate the number (quantity) of corrective maintenance actions.b) Calculate MLH/OH (Maintenance Labor Hour per Operating Hour)

Expert Answer


T = 10000 hours

MTBF = 250 hours

λ (failure rate) = number of failures/T

MTBF=1/ λ

λ = 1/ 250 = 0.004

Number of failures or corrective actions required = 0.004 *10000 = 40

Total maintenance labor hours = Mean corrective maintenancehours * Expected number of failures = 40 * 2 = 80 hours

MLH / OH = 80/10000 =
