Subject: RCM in electronics??
Message:
RCM concepts builds around OCM and the checking interval depends on the Potential Failure Interval. It is only true for mechanical systems where failure modes exhibit warning signs when they are about to transform to potential failure. In view of this, can RCM or OCM be applied to electronics as well? Please advise

Subject: Slip Ring Reliability
Message:
Hi,
I am trying to find out if there are any slip ring reliability models in existence. If there are not, would it be correct just to model all the items separately? Thanks in advance.

Subject: MTBF assignment
Message:
Can we estimate a MTBF target like that :
reliability performance system is any failure should occur less than once per year. As the system is used 18h per day, the MTBF must be equal or greater to 6,570 h i.e (8,760 / 24) * 18.
