Hi all,

I'm trying to find a solution for the below scenario:

I have 3 sources creating 3 different types of products, which i have labeled 1 to 3, corresponding to each of the source.

I want to have all my Queues accept the following combination:

Stack Vertically Type 1 - 3 boxes stacked

Stack Inside Queue Type 2

Stack Inside Queue Type 3

All Queues should allow for combination 1 & 2 & 3, but only type 1 should be stacked vertically.

Considering the queue max content of 7 items, the queue should accept 7 spots to be filled, but in case type 1 is in a queue, then it should accept to be stacked vertically until it reaches 3 stacks.

The queue only allows the selection for either options, so wondering what would be the solution.

I have attached a simple model to reflect the scenario.

Might I suggest to use a Floor Storage instead of a queue? Since you mention "spots" it seems to fit much better with what you want in terms of behaviour. The Slot Assignment Strategy can be adjusted to allow three Type1 items per slot but only one if it has another type.
