Warehouse management with conveyor

Hello, I am trying to simulate a warehouse where a forklift takes boxes from the conveyor to the racks in the first step and then takes the (smaller) boxes to the assembly line.

I want to achieve the following:

in the warehouse rack there should be only 2 boxes of each type. When there is less than 2, the source has to offer a new box to the conveyor and the forklift can put it in the rack.

So at the start of my simulation it already goes wrong, I would like to start offering each type 2 times and then only when one is needed in the rack. Can anyone help me?

There doesn’t exist a conditional source. A source is a primitive object. It creates items in an amount and time only. You want a behavior that creates items upon an event of a rack object. Then you can create objects by source code or process flow. It would look like, by change of content or exit of an item from a rack, you create exactly this kind of object in your model anew and move it into an object near your source preferable in a queue. Then this created item can participate in your flow.

A simple option would be to create two tokens per type which each create a box and manage the transport into the rack, then wait until the box leaves the rack again and loop back to the start.

When unloading the items to Queue1 you either need to use the "Move Object" activity or run the "Unload" for each item individually in a sub flow.
