What I would do:

- Create one token per AGV. Assign each token a fixed AGV and use a label to differentiate between the two types.

- The left side of the Process Flow can stay as it is. The right side can actually be simplified, since you can check if the tote still has space before you try to find an item.

Depending on the type of AGV, check the content against a capacity of 6 or 12 and send the token to one of two Find Item activities if there is still space.

You still only create a single token, you did not create a label that could be used to differentiate between the types of AGVs and the settings of the Decide and Find Item activities don't make much sense to be honest.

Your source should look something like this:

I added another Decide activity to make the logical flow hopefully a bit clearer.

For the Find Item queries, compared to the previous iteration of your model you only need to add further condition for the correct type in the activity on the right. (WHERE item.slot.storageObject=$1 AND (Type == 5 OR ...))
