Good day to you,
yes i am new in RCM .
Now i have completed the RBD in my system .Form this i found the reliability is 73%, among this top5 components are contributing 25% of unreliability .Can i do the RCM based on this result.
Congrats bbabu on your accomplishment on RBD.
(You have another thread on RBD on which you may write a closure post describing your achievement. If possible, can you share your RBD there for the benefit of others)
2. Top 5 components out of how many? How is the distribution of your MTBF? Is it possible for you to share your calculations, without compromise on secrecy.
3. The first step towards RCM analysis is to take a decision by the top management to decide whether to go for RCM or not.
4. If yes then it is required to form a team of analysts, anywhere between 5 to 10, composed of maintenance engineers, equipment specialists and technical writers.
5. Train your team on the rudiments of RCM.
I wish to add from my experience on Indian Railways as a member of DMG (Diesel Maintenance Group). We received our diesel engines from ALCO (American locomotive company)- designed for their environment, with a five inch thick Maintenance manual with a number of supplements (obviously a result of ALCO's RCM analysis). We found to our disbelief, that many of the important components viz: Turbocharger, speed governer, Main bearings, piston rings etcetra were failing much faster!! May be due to higher temperature in India (as per ALCO's version) . So we conducted our own RCM analysis combining PERT & CPM. By using Critical Path Method I was able to save 13 hrs. on POH (once in 3 yrs.) with better results. Therefore I recommend to combine CPM with RCM analysis for improved results, and also consider the topographical situation of your customer, if you are a manufacturer.
Bon voyage on a less treaded and difficult path of RCM. Wish you best of luck. You will need it.
