The system that i am currently trying to simulate involves two operators that each have a workstation that they are assigned to, the flowitems arrive to the operators from the same spot (one flow in but two workstations to "process" the items). The issue I am facing is a very particular one that involves when an operator goes to break. Because there is only one flow into both operators, i need to ensure that the operator does not go to break if they have been assigned an item (it'll hold up the other operator that is not on break because it has been assigned to the other operator). Currently i am using the exit transfer of a conveyor to decide which operator is available (upon arrival of a flow item to the exit transfer), the odd occasion occurs when the item is assigned to an operator (they are available), but then on their way to picking up the item they go to break (the item will just sit there until they return from break, is there a way to reassess which operator is available to save myself from this fault..)
