finding slot in the same type

using elevator to pick an item out_2.fsmI am trying to send items to the slot according to their type. For example, if the Level 1, Bay 1 is occupied with item labelled type 1, then the remaining items that enters the same bay and level should be the same type. however, if the the bay/level is empty, then any type can enter that row. Do you know how can I go around with this?

You will add a two step approach. Find a slot matching with Type and then if slot variable is stlll NULL then you choose a slot that does not contain any assigned slot item. There are several given answers here for each single condition alone. Please combine them yourself.

slot.slotItems[1].item.Type = $1.Type

Get matching label called Type on first slotItems item label and compare it with a passed external parameter assigned as item reference in special identifier $1 into the string query clause.

'$' keywords

https://docs.flexsim.com/en/24.0/Reference/CodingInFlexSim/FlexScriptAPIReference/Warehousing/Storage.System.html#Method-findSlot

in reference manual there is the label completely passed in and not just the item reference.

using elevator to pick an item out_3.fsmI added the query on find slot activity but it seems to be giving an error. 1720455537969.png

To check if the type of the first slot item matches, there must of course be a slot item. So first check if this is the case in the query. You can also define multiple queries in a single Find Slot activity. The second one will only be run if the first one is unsuccessful.

Hi Felix, thank you for that. It works now but I encountered another problem. It seems like there is one box in there that does not recognise that it has entered the wrong bay. I have tried several methods to have the token come in 1 by 1 rather than at once but it seems like this one token still went to the wrong slot. using elevator to pick an item out_3.fsm1720511666196.png
