lambda_MPF,DP compute with Medini

Question

Hello,

Medini allows to compute the value of LMPF failure rate

I would like to add a column in the FMEDA, where we can see the value of lambda_detected as well.

Any help, please?

Thanks and regards,

NL

Hi Nassima,

do you want to display it for each individual failure mode/evaluation group or for the complete HW part? The second option is probably more tricky as it would need to consider the options to use variants and multiple safety goals within one sheet.

For the first option you may define an appropriate derived property for DC Failure Entry which is calculating the value based on the existing numbers - in OCL this would look like this:

if self.lmpfViolation
 then
 self.remainingFailureRate-self.spfFailureRate-self.lmpfFailureRate
 else
 0
endif
