How to send flow items to multiple racks in order using process flow

[ FlexSim 20.0.5 ]

Hi,

I would like to simulate the loading flow items of operators into multiple racks in order. I partly managed it with standard logic however there are some unexpected behaviours so I want to use process flow to optimise the simulation. I created a process flow and I get stuck at the station setting for unload activity. I tried to group the racks together and sample the group in this station box however it does not work.

Could you please help me to set the destination of flow items to multiple racks in order? (fully fill rack 1 then to rack 2, etc)

I uploaded my model here: ReplaceFlowItemsInMultipleRacks.fsm

Best regards

@Vuong V2 If you first get a slot where your product can go then the rack follows automatically. Please read up on the Key Concepts About Warehousing, how to get a slot for your item and then get the rack from the slot and unload to the rack. The warehouse system looks at all your racks together and it will automatically fill it up in the right order if the racks are added in the right order

@steven.hamoen Thank you so much for your help. I have tried with Storage.system.getSlot() method, but it seems that I do not use it right, so I keep get this Task Error:

With None Address Schemes, I use this Storage.system.getSlot("Rack1-1-2-1), with created Address Schemes, I use Storage.system.getSlot("1-A-1-2-1"). My Storage System with a Address Scheme looks like:

Could you please have a check on my model?

This is my model: ReplaceFlowItemsInMultipleRacks.fsm

@Vuong V2 I have exactly the same problems that @Jörg Vogel describes, I can't see your pictures and I can't download the model. So I have taken your first model and added some functionality. Please take a look and see if this helps you further

@steven.hamoen Thank you so much for helping me. I have tried to use the Storage.system.getSlot() method to get the first slot of the racks into the station field of Unload activity. I have set an Address Schemes in the Storage System and put the slot address string into the station field of Unload activity as: Storage.system.getSlot("1-A-1-1-1"). However, I keep face the Task Error: "An invalid task has been encountered".

Could you please have a check on my model? ReplaceFlowItemsInMultipleRacks.fsm
