Hello! In the attached model, the ASRS vechicles can lift 55 pallets per hour. I am trying to increase that number to 80 pallets per hour approximately. I can not change the specs of the machines though.
Is there a way to achieve that?
If the ASRS can only carry one item at a time then the only thing you can do is select the closest items for picking. It's not storing items so you can't make sure every journey is efficient by alternating between storage and retrieval jobs, or by choosing pick/placements that are close to each other. Also if you choose the nearest items without any replenishment, then the system will over time become slower as the items to pick are further away.
Also check the states of the ASRS vehicles to see if they are always busy or if there are any losses for example if the conveyor they are feeding is occupied and they are unable to unload.
If the conveyors for example are always busy and so the asrs can not unload pallets, the solution is to only change the structure of the conveyors right?
Also in order to select the nearest location for the asrs i need to do some adjustments to the process flow?
Yes - the conveyor capacity and/or prioritising the infeeds when they are full.
I think at the moment you're finding pallets randomly (ORDER BY RAND) so instead of that you would order by slot.bayID or a distance calculation.
There is another option if the conveyors are busy - and that is to temporarily re-store the pallet in the rack near the conveyor drop, for final placement on the conveyor when that becomes free.
