How to calculate priority of conditial Severity, Occurrence and detection in Windchill QS 10.2

With the new AIAG/VDA combined guideline there is now the neccesity of calculating the priority with a list of combined cobinations of Severity Occurrence and Detection, instead of the RPN or the Special Characteristic (Risk Matrix).

Together with the risk matrix it is possible to calculate the risk priority with calculations:

 

This calculation will give a certain predivined priority for Severity 7 combined with an occurrence higher than 3:

IfThenElse(([FmeaTable.Occurrence]==0),BLANK,([FmeaTable.FmeaValue2]==7?[FmeaTable.Occurrence]>3?1:BLANK:DO_NOTHING))

 

I would like to add also a certain range of the Detection rating in this formula. Does anyone has any suggestions?

 

Thanks in advance
