I need help, in my model I was able to simulate so that the boxes in the process output are sent to one queue at a time, but in the second step the processor also distributes using the same logic. I need the processor to send the boxes to the queue that is totally empty, if all four queues are in some box the processor should wait for a queue to be available.
In the attached image, the right one would be for Crane1 to route to the empty queue and not complete the queue being emptied.
