FTAs with different Calculation Types in a single system file?

Hello everyone,

in the lifecycle of our product we have to calculate different FTAs, which are based on different calculation models (Time dependent FTAs + Lambda Tau FTAs). Unfortunately, if I calculate a FTA with a calculation model, the calculation type will be fix and cant be changed anymore to calculate the other FTAs with a different calculation model. This means for us, we have to have two system files for the same system, one with time dependent FTAs and one with Lambda Tau FTAs.

I talked to someone who worked with Relex/WQS for a long time and he said there might be a chance that I get it to work with configurations but he couldn't promise it for sure. I tried it with no success. I couldn't find anything about that in the Reference Guide either.

Is there any way to have FTAs with different calculation models in a single system file? Or can someone confirm, that there is no way to do it?

Thank You! Best wishes.

Hi Torben,

There is no way to combine different calculation models. They were purposefully separated because they have different underlying math models.

You could potentially use a Time Dependent Tree and use different Time Exposures to enable non-homogeneous calculation.
