How to use Operators to move flow items from Queue to Queue?

ajay_bhesaniya — Wed, 15 Jun 2016 19:20:56 GMT

[ FlexSim 16.0.1 ]

I have attached the sample model I am working with. I want to use a Dispatcher and 2 operators to move flowitems in one directions between the following Queues;

a. Queue23 to Dump10M

b. Queue31 to Dump 20F

c. Queue33 to Dump 30F

d. Queue27 to Dump 40F

I connected the Dispatcher to the Center Port of Queue23 and connected 2 operators to the Dispatcher. The flow items currently move from the Queues to the Dumps but I would like the Operators to pick up and drop instead.

Any insight will be much appreciated!

So one of your problems in your model is that the conveyors don't have any logic dictating which items go where. So they are all going to the First Available Port (in this case it's going to the Loadout queues you have designated.) You can change the flow of the conveyor items by clicking on the little square at the end of the conveyor.

In your model that I adjusted, I just chose to sort them in Round Robin fashion, you can change this to an expression or whatever you need.

Secondly you had all the port flow from the conveyor to the Dumps directly, you need to have them flow to the Queue, and have the Queue flow to the Dumps. Then just attach the center port connection from the Dispatcher to the Queues and have the Queue use center point connection as it's required transport.

You can take a look at the model I've reattached.

The model worked fine until I imported a new set of demand in the 'demand' table and changed the 'trackcurrenthour' variable to repeat every 24 hours since this is a daily demand. The Sink (Terminal) is not pulling demand as it did before.
