in the attached simple model, the objective is to stop filling the queue when it meets a threshold amount in this case 95 The trigger to start refilling the queue would be when the queue size is less than 20.

How to stop / start filling queue based on queue size
FlexSim 19.1.1
Here's an updated version of your model that stops the queue from filling when it reaches 95 items and starts filling again when it reaches 20: fillqueueanswer.fsm
It works by using Process Flow to check when the queue increases to 95 or decreases to 20. When it increases to 95, it closes the input port of Queue1, and when it decreases to 20, it opens up the input port again. I also set the max content of Queue1 to 95 so that it couldn't be overfilled by the operator unloading multiple items at once.
