Flexsim crash

Hello,my model can works, but Flexsim crashes directly after execution. Is it because I use too much process flow? If so, is there any smart way to help me simplify my process flow?

Please see the attached .fsm file.

warehouse case.fsm

Regards,

Shawn

The model crashes because a transporter unloads a pallet to Separator7 while it is still processing the previous one. This causes the new pallet to be send to the queue together with the content of the previous pallet. When the process time of the second pallet elapses, it is not in the separator anymore which causes the crash.

How you could fix this:

- Unload to a queue that leads into the combiner, so the new pallet would wait for the process to finish.

- Set the process time to 0, so there is never any wait time.

- Add some logic to the process flow that checks whether the separator is empty before the transport unloads to it.

You have to do this for all separators of course, #7 is just the one where it happens first.

Hi Felix,thanks for your answer.
Now I know how to fix that!
By the way, can I get my transporter and operator back to the starting point through preferredpath?
