how to make an operator pick up a product from a queue?

[lostpary]

hi guys
i have been having this problem, i have three queues each connected to a server, and a conveyor which delivers products to the queues.i should call operators to pick a product from a queue, carry it to the server, do some work on it, and then be free.but the call operator codes seem not to work on queue, since the operator doesn't know which product to pick and gets stuck.
can anyone help me about this?

Hi,

A similar question has been discussed in the following topic:

You will find some suggestions and an example model there. I hope that this answers your questions, if not, just post again!

Hello Parastoo,

I checked your model and found out what the problem is. The problem occurs because of the queue capacity > 1. When a problem enters a queue (and triggers an operator call) and before this product exits the next products enters (and triggers another call) the operator gets connected to the wrong product. The model will be running nice when you make the queue capacity 1. A solution could be to add 2 queues after the conveyor: the first for "waiting" and the 2nd with a capacity of 1 and having the triggers to call and free an operator.
