question

Hey @Borja Lorenzo, sorry for the confusion with your account and that it's taken so long to get back to you. I've looked at the model and I have a couple of ideas to share.

First, having the AGVs pick up multiple items is a good idea, but you would need to implement something in the Control AGV Process Flow for that to work. You could change the Require/Request fields in all the Pull from List activities (connected to the Cajas a transportar List) to pull multiple items at once. You would then need to set up a sub flow to load all pulled items if multiple items do get pulled. Alternative, you could use a Move Object activity to load/move all items at once into an AGV. You would also need to use a sub flow to unload each of the items one at a time (you wouldn't be able to use Move Object since it's possible for each item to go to different destinations).

You would also want to make sure the items are dropped off in the correct order to make sure the AGVs are not going around the loop multiple times. There are a couple of ways we could do this depending on how you want it to be done. However, I'm going to suggest a different change to the model first, so I'm not going to include an example or give a more detailed answer on how to do that quite yet.

One thing I have noticed is that the model could use better timing. When an item arrives at the CargaAGVs Queue, that causes the AGVs to pull from the List based on a first in-first out system. So the first token trying to pull from the list is the first token/AGV to pick up the item. I know you mentioned trying to set up something with shortest distance, and that could help, but I think there is a better way.

I think it would be beneficial to set it up where the AGVs first travel to the CargaAGVs Queue, and then try to pull from the list. If it can pull something, it will pick up the item(s) and deliver them. If there is nothing to do, it goes to parking to wait for work.

If you look at the AGV Process Flow Templates, these templates all use logic that cause the AGVs to travel in a loop looking for work. The AGV with Basic Parking template also includes logic for parking when there is no work to do (waiting for when there is work to do), as well as allowing AGVs to pick up multiple items at a time.

I suggest looking through the link, maybe even use a new model to go through the Basic AGV, AGV with Work Forwarding, and AGV with Basic Parking templates to see how they work and see if the Basic Parking template could help with your model.
