Repairable System Reliability Analysis: Uptime/Downtime Hours, Failure Modes Data

Good Day,

I am a novice reliability student that is assigned a task to assess Preventive Maintenance strategy of the drive train within a STS Gantry Crane. I have field performance data from 2009-2012 on this repairable. I have data on the expected operating hours of the system as a whole for each month and after a review of the corrective maintenance log I segregated the hours into uptime hours and downtime hours. I have calculated the Availability value of the system from the information.

I have the list of PM tasks and the frequency that it is performed.

I was asked to determine if the freqency of the PM task was an overkill.

Any Advise on a statistical analysis that can help me assess the time and cost savings that can be deived from the above infomaton. Can I correlte the above variables to derive insight into improvements in the maintenance strategy applied to this system?

Also is there an Excel template that I can access that can faciliate the analysis.

I have access to IBM SPSS and SAS JMP. A sample file in the format suitable for these software would also be appreciated

Thanking you in advance
