Pull using list

[ FlexSim 21.1.4 ]

Hello to everyone. The simulation I prepared is more complex, but I prepared such a model to explain my problem. I have 2 different output conveyors. I have 2 processors on each output. I have some restrictions.

1- 1 of each processor group can be used. For example, if processor 1 is full, processor 2 should be empty.

2- There should always be 2 extra products on the conveyor that will go to the 1st exit and the 2nd exit

In short, what I want is 1 box in processor 1 or processor 2, 1 box in processor 3 or processor 4. and on the conveyor there should be 1 box to go to exit 1 and a box to go to exit 2.

Since my real system is more complicated, I want to pull items to the conveyor with a list.

Sorry for the long and confusing explanation.Example.fsm

Hello @Ulaş A2,

I understand your first requirement. I set up on entry and on exit triggers to open and close the paired processors so they only ever have one item in either processor at a time. In the triggers, I reference the paired processor by a center port connection. If this does not logistically work for your larger model you could create a label on each processor that points to its paired processor and then use that label as the reference in the triggers.

Could you try explaining your second requirement again?

Hi @Jeanette F ,

Thanks for your answer. There can be a maximum of 2 boxes on the conveyor. One of these boxes should be for output 1 and the other box should be for output 2. I hope I could explain

Hello @Ulaş A2,

The easiest way to limit flow items based on a label is to use a zone.

And set the partition to be the Exit label and then to limit each partition.
