Pull Flow Process

I have a combiner that requires different raw material from different Queues to process a reference. I've been having issues doing it with the Process flow option.

Here is an example of what I'm asking:

A combiner requieres 2 items from Source1 and 1 item from Source3. Until the objects requiered don't arrive to the combiner, it is not going to be possible for the combiner to join the components.

Here is our model: FLEXIMPROCESSFLOW.fsm

@José Juan Ramírez Gutiérrez, the "Combiner" in your model is simply a Queue that looks like a combiner. I see you're trying to combine items onto pallets with Process Flow. You're pushing items onto a list by partition based on the Queue they're in. Then you're pulling from that queue alone because you're pulling based on partition ID.

You could take a look at this post I made with a sample model explaining how you can use an actual Combiner to change combiner quantities and types.

Hey Kavika, I get what you are saying but in the simulation you where showing to only pack items of just one type but using different types of pallets. For our project, we need to pack items from different types at once. Would you be able to explain or show us how to do that using the a list and process flow, as we showed previously in the modelo.

Thank tou

@José Juan Ramírez Gutiérrez, then maybe you want something like this:

combiner-queue.fsm

queue-combiner.gif

It spawns all boxes from 1 Source and all Pallets from a different Source. It constantly listens for all 3 recipes. When one is available, then it will acquire the "Assembly" queue to put all the boxes on a pallet and wait for a few seconds to "assemble" the pallet. Then, it will delete that pallet and create one of the finished product objects.
