Random release from the queue

Hi I'm making a model where there are multiple different "packages" inside of a queue and I would like to release them from the queue at a random time over the course of day and ideally release a random package from the queue but only one at a time. I have tried all sorts of different trigger combinations and can't seem to find one that does what I am looking for. Does anyone know how I would go about accomplishing that

You can solve your issue using process flow module.

I'm not too familiar with how to use process flow are there any tutorials or something I should look at to help me solve my problem.

You can find the tutorials for process flow in the user manual

I've attached a sample model that will do what I believe you are describing.

In Queue1, on the Flow tab, I set the Send To Port to "Do Not Release Item", which will hold flowitems until they are released elsewhere. Then I created a User Command called RandomRelease. When this command is called, it will release a random item from Queue1 to Queue2. And to add the randomness to when a flowitem is released, I used the MTBF/MTTR function. In that function, instead of taking the object (Queue1) down, I call the RandomRelease User Command. This give the flowitem release a random model time. The model really doesn't need the connection between Queue1 and Queue2 but I put it in there just so the model flow could be seen.

Take a look at the model and see if something like this would work for your situation.

Thanks.
