If performing one more preventative maintenance activity per year from the data below, in reduction in the number of failures per year from 2 to 1.5 (i.e., 3 every 2 year), is there any improvement in the systems operational availability, if so, by how much?
Operational cycle = 2000 op hours/year
Support life = 5 years
Failures that required corrective maintenance = 2/year
Repair time per failure = 40 op hours
Preventative maintenance activities = 1/year
Preventative maintenance time per Preventative maintenance action = 9 op hours
Average wait time for repair materials for corrective maintenance = 10 op hours.
