The operator attends to 2 machines, one machine produces type A pieces and the other type B pieces, until the job is finished 0 pieces in the input queue, he can travel to another machine.
I didn't see you post an example model, so I created one. The model uses Process Flow. In the Process Flow, one token is created that represents the operator. The token acquires the operator and then pulls an item from the an item list (Queue1 and Queue2 push items to the item list). The operator moves the item and then tries to pull more of the same item based on the query shown here:
If the operator is unable to pull the same item Type, then it is assumed that the queue for that item type is empty and the operator then looks at a different item Type. So, the effect is that an operator loads all of the items until the input queue's content is 0. I hope I understood your question correctly. Here's the model: two machines one operator.fsm
