When many Queues want the flow items to move from List...

I want to make many queues of five hundred pull the needed item from the list and route to the needed like attached screen.

Whenever the flow items exit from five hundred queues, the Queue1,2,3 send the message to the Queue_in and then Queue_In pull the items from List of global ItemList1 of the Queue_List.

How can I make it?

With lists, there is no need to send messages. In each Queue's properties window, on the Flow tab, you can use the "Use List" option. One (or many) queues can push to the list, and one (or many) queues can pull from that same list.

It sounds like you want to make 500 stations or cells, that are repetitions of the model you have shown. If that is the case, you can use the option above. You just need to push the items to a partition for each cell, and then pull the items from the correct partition.

You looks like not to understand my issue. The queues of 2,3,4 do not push the items to the list.

Above is a similar picture of my issue a little is different.

Push items can be happen initially until first flowitems transfer to the many processors. And then flow items should come in before the processors finish the processing. Each cycle time is different from each other. And the queue capacity before the processors is only ONE.

Yes. The needed flowitem should come and be waiting in the queue before the processor finish the job.

My issue is above. "Pull system" is my need.

The connection between Queue_List and QUEUE_In can be connected or not. Anything is OK.

I need help to solve my issue.

Above is some near to my issue. The processor has only ONE queuing item before itself.

The elevator can't have to keep the item.
