How can I index an AGV to load another item?

Hello, I was wondering if someone would be able to help me implement a load-index-load scenario. At Station A I would like to wait until there are 2 items waiting at the queue for pickup, then dispatch an AGV to that location to load the items. What I would like to happen is for the AGV to load one item, index to the next CP, then load the second item in the back half of the trailer before leaving to drop off the items. The AGVs are custom 3D models, not the default AGV model that comes with FlexSim. Thanks!

All that you really need to do is to change the location of the second flowitem that you load. Attached is your model with the change that I made. I added a Change Visual code block after your second load.

Is this what you were looking to accomplish? Here is the model: agv-index-and-load-jn1.fsm

Jeff, thanks, that fixes the issue with indexing and loading, I appreciate it.

However, one more problem I had which I didn't realize was that two AGVs are dispatched to the same pickup and the dispatching is messed up, the second AGV to arrive wants to pickup a non-existent item. Would you be able to help fix that? Sorry, my process flow expertise is on a very novice level right now.

@Michael Kramer I reposted this question here as it is a separate issue.

Hi Jeff.

Running your model, I met a error in about 325 seconds.

P.S. I use Version 2016.0.1 to open it.

Here is a link to a "fixed" model that should work for you.
