Hi,
In FMEA normally we'll calcualte the RPN as Sev x Occ x Det,
but recently I came to know that in DFMEA the RPN calculation method is slightly difference. i.e.
First Calulate RPN for Failure Mode (RPN FM = Sev (Max) x Occ X Det(FM))
and then RPN for causes,
but in calculating RPN for causes, I was told the formula as
RPN C = Sev (max) x Occ x Det (Min (FM, Causes)
Example
Assuming
for Failure mode RPN FM = 5 X 5X 3 = 125
for cause 1 suppose if i get Sev = 5, Occ=5 and Det = 4,
I normally calculate as 5 x 5 x 4,
but i was told to calculate as 5 x 5 x 3(Det of FM)
is there any reference to this method???
