Push item to list, move with AGV and pull from the list

[marko_g]

[ FlexSim 16.2.2 ]

I am trying to push an item to a list and later I am pulling the item with a WHERE clause? I make something totally wrong, because system not working. The item receive number at source, moved with AGV and on sing it is pull when the number match. E.g. From Queue 1 to Skladisce. Can someone look where is my mistake?

Can you attach your model?

The items you're pushing to the list don't have a LoadType

Also, since it looks like each item can only have one LoadType, this where statement won't work.

"WHERE LoadType == 1 AND LoadType == 3 AND LoadType == 4"

That where statement means that the item has to be a type 1,3, and 4 all at the same time. If you want to pull all types 1, 3, and 4 you need to use ORs since the item can be a 1,3, or a 4.

"WHERE LoadType == 1 OR LoadType == 3 OR LoadType == 4"

Thanks. So if i want to move with AGV from Queue D1, Queue D3 and Queue D4 to Queue R134, can this be solved with LoadType nr.?

How can I assign that box from Queue D1 receive LoadType 1?

Thanks for help.

Actually, since you're using the AGV template you don't need to use your own list. In the attached model I created port connections between Queues D1,D3,D4 and Queue R134. Then I changed the Send to Port on the D Queues to First Available. I also turned off the Pull Strategy on Queue R134.

But if i start this agvworks, no flowitems moves from D1,D3 and D4 to T134. AGV travel empty all the time. I also want to move some items from base floor to uper floor (via elevator) and move some items in the uper floor

[Matthew_Gillespie]

It wasn't picking up from D1 because you didn't have a NextLookForWork connection to D1.

agvwork2.fsm

If you need help using the AGV Elevator please post a separate question detailing what you've tried and what you don't understand.

Yes, sorry, my mistake. now it works perfect. But if i want also to move items from (koluti za zaluzije) to uper flor to koluti za zaluzije? Will in this case i need my list or is it OK just to make port conestion between this two source and sink?

Hi, just want to make same as you in agvwork2.fsm in my original model with 2 floor, but it wont work. The AGVs dont want to move.

Take a look at this documentation page, https://docs.flexsim.com/en/19.1/WorkingWithTasks/AGVNetworks/AddingElevatorsAGVs/.
