First available with reversible conveyor

first available -5.fsm Trying to send one box to the first available workstation, the cell has 4 work stations with reversible conveyors but still getting errors and it sends 2 boxes to the same workstation. I need to send one box at a time to the available workstations without using the flowchart. See attached

FlexSim 23.2.2

Don't use this approach - it's not safe. Pull the station to route to from a list instead and push the station back on the list when the process is finished. If no station is available then have the part wait at the routing decision point. The stations are a Decision Points, so you can send to them - you don't need the extra ones. Detect the exit from the reversed conveyor to set it to forward mode again. I used a zone capacity 1 to reject the second trigger of the station arrival by the same part when reversing (to ignore it).

Jason or Paula,

Could you please fix the logic when you have time, and then send it back? I'm still confused and can't run it. I really would like to see the right logic for this case to avoid any issues in future. Please see attached.

Thanks,
