Running different operator arrangements on different shifts

I am working on an assembly process where I have 2 machines processed by 2 different operators in the first shift, then 1 operator working on both of the machines in the second shift.

I've been trying to find the right way to simulate this with dispatchers and preempting in the processors, but I keep noticing that even though the operators are scheduled to work they are idle and the machines' status is waiting for operators. I would like some directions on how to do that correctly, and what are the most important settings that I should pay attention to?

Attached is a simple example of 2 shifts as you describe.

In the attached model, I have two operators that work Shift1 and one that works Shift2. The processors are connected to the Dispatcher with a center port connection. The operators are connected to the Dispatcher with output port connection (click A key drag). But the important thing in working shifts is that each operator needs to be connected back to the Dispatcher with the A key as well. This is so if they go off shift, the task can be sent back to the Dispatcher for another available operator. In this case, that would be to the next operator(s) on shift.

Take a look at the model and see if it will do what you are wanting it to do. If you have any questions or problems, please let us know. Oh, and the model is built in the latest version of FlexSim.
