As you can see in the photo below, I used a "Create TS" activity to generate tasksequence for AGVs, in which i set the Priority value 1 and Preemption mode"preempt,aborting all". (All other TS with the default setting:Priority 0 and Preemption 0). But as the model runs, i found that when a new TS was created , the current activetasksequence still exist.
I'm now wondering how can this happen?
you found my example model for priority and preempting value for the question:
@Jörg Vogel , Thanks for your reply, i've seen the answer that you posted through the link up there. I've run my model a bit more times and found that the tasksequences may be created simultaneously. There was no active tasksequence the moment that two tasksequences were created, so the preemption mechanism could't work. Can i interpret it this way?
The preemption mechanism expects an active tasksequence, if it gets into a dispatcher (taskexecuter).
