a questions about conveyors

Hello,

I have a queastion for the model attached. It is an AS/RS model with 4 exit transfers as shown below:

Because the operators have load and unload time when picking up a pallet, after a while the conveyors are being congested with the reasult that the model stops. Is there any way i can manage to stop the congestion without adding exit transfers? Or this is the only way?ASRS - 4 CB.fsm

Software Version:

What is meant to happen with the boxes and pallets when they enter the buffer? At the moment they just seem to be shuffled in and out by the transports - none of the boxes leave the buffer1.

Also - you've doubled up items being pushed to lists - the Buffer1 Process detects items entering and pushes to Buffer Items and the buffer itself has an entry trigger that is is pushing to the list "operator_picking" off which nothing is ever pulled.

I've uniquely numbered the boxes at creation so you can see what's happening in the operator_picking list.

I think the model is in this state since you originally specified the problem differently but have continued to use the same process flows for a different purpose for which it is not longer fit.
