How to priorize events

Hi,

there is more events (occuring in the same time), they have to be priorized:

Event1
Event2
Event3

If Event1 occurs, then should be followed the path from that. Event2 and Event3 have to be ingnored.

If Event2 occurs, then should be followed the path from that. Event3 has to be ingnored.

How to model it.

There is two ideas - s. attachment.

Any further ideas ?

Thanks a lot in advance,

Michel
