Setting Rack Storage System based on SKUs and Batch

[ FlexSim 24.0.0 ]

Hi All,

I want to simulate the ASRS storage system. I have 3 SKUs: A, B, C, each SKU has 2 batches: 1, 2 and the rule is only same SKU and Batch item can store together in same level on the rack.

For Example,

SKU A Batch 1 has 13 items 10,000 pallets
SKU A Batch 2 has 13 items 14,000 pallets

until

SKU C Batch 25 has items 1,000 pallets

Please give me some idea or recommendation about how to set up in the source, storage system, the rack and so on.

Thank you for your answer!

I've done this by using a Find Slot activity with two queries. The first query searches for a slot that already has matching SKU and Batch labels. If it does not find a slot the second query is used which searches for a slot that has not yet had the labels set (at default value 0 - set in the Storage System properties or painted on as the reset value).

If the second query is successful, the On Success trigger sets the labels of all slots in the same level to those of the item. So further items of the same SKU/batch will find those slots in the first query and different combinations can not find them anymore in the second.
