Pull items according to two requirements on a Queue

I need that the Queue4 select the best item according to two requirements (variables)

1.- Best minimun number on a label (sec)

2. Product B has to be separated by five A products

Is there anyway to do that?

items.fsm

hope somebody can help me with this!

The following attached model will hopefully help you pull the items as you outlined in your question.

It works by pushing the items to a list using Queues 2 and 3 as shown in this image:

Items are assigned to a partition, which can be pulled from later in the model by Process Flow. The token in process flow goes round robin style - getting 5 of Product A and then 1 of Product B on the next time through. The image below shows how it pulls from the item list:

Let me know if you have questions about Process Flow or if this didn't quite capture what you wanted for your model.

Looks great, product B is being separated with product A, but there is something missing.

Product A and B has a label called "sec", that represents the sequence that the product should take to enter to Queue4, so, the most important thing its to respect that order, however if its impossible to respect the label "sec" because of the separation required by the process , then the software has to forget "sec" and put the separation between products.

Thank you man, i hope i can make something from this example.

@Alex Gf This is actually pretty straight forward with lists. If you open your list activity and open the advanced button you can add fields to the list. If you add a label field and call it "sec" it should have that field with correct value (if the item also has the label sec)

In the pull activity on the Query/Object field you select Order By and the field "sec" and you should be ready
