Can't Load from queue using AGV

Hello,

I'm working on a school project and I found myself stuck when I wanted to pick up items from a queue using an AGV after an "Wait For Event" in my process flow. :

My problem is when my AGV arrives in front of the queues, I can't make it load the items in there using the load command as it shows :

CantLoad.fsm

I just want to make my AGV pick up the items from the queues (the 6 ones on the left) and then travel.

Thanks a lot !

Software Version:

FlexSim 23.2.3

agv queue agv load

Hey @Mehdi, several things to help your model.

First, resolve all exceptions you're getting. If you have an exception, it means that something is broken. You have two main errors.

Firstly, in your ProcessFlow, a Create Object activity got a bad return character somehow.

Go into the Create Object properties:

And at the end of the code, remove the new line character and add some new ones (backspace till you get to the code, then hit enter a couple times):

Next, your Queue Déchargement Ecrous was not pointing to a Task Sequence List; make one:

When running your model, your AGV gets stuck on the path. Make sure all paths are connected correctly. You can do so by right-clicking a path, going to Refresh Path Links, and clicking Entire Network.

Finally, several things wrong with your ProcessFlow2 code where you're loading an item.

You have the Executer/Task Sequence set to item when it should be set to the AGV picking Executing the Load. Also, you have the item being picked up as "token.item", but that isn't a label you've set on the token.

Fix these things first before proceeding.
