Question 2: Calculate the achieved availability for equipment, knowing the following related data:
(a) ‾Mct = 0.85hr
(b) ‾MTBMu = 2.75hrs
(c) ‾Mpt = 2.75hrs
(d) ‾MTBMs = 1,750hrs
N.B. ‾MTBMu = Mean Time Between Maintenance (Unscheduled) MTBM s = Mean Time Between Maintenance (Scheduled)
Use excel and attach file as embedded file in word document/ upload file in Moodle with your analysis.
Question 3: The contract requirement for an equipment item for maintenance is 63 min. and the established risk factor is 10%.
A maintainability test is accomplished and produced results given in the table below for the 40 testing tasks (Task times are in minutes)
