Hi, I have 2 sources (2&4) that generate items that are stored in the rack. Source 9 represents an order coming in, that needs to be taken from the rack. How can this be simulated?

@Lean van der Walt

I had to fiddle a bit because I didn't want to use process flow ( nothing indicates that you want to use it) but I have it:

  1. I added a dynamic label Ready to the Storage list
  2. OnEntry of Queue9 pulls an item but leaves it on the list and set the label Ready on the item in the rack
  3. Queue10 pulls items where Ready > 0
  4. I added a back order reevaluation event to let Queue10 knows that something changed

The model is attached

I changed your model a little bit. Now the onentry of the queue pulls the item from the rack. I gave the items different labels so you can easily split them again when they leave the queue.

In these models you might also check out process flow and built the complete logic in there.

Thank you for your response.

None of the items appear in the queue? The logic for the model is that you have deliveries coming into a warehouse (sources 2&4 represents these orders) and the warehouse receives orders (source 9) to ship these items. Once a order comes in the item needs to be retrieved from the rack?

Will you be able to demonstrate this to me?
