Question regarding combining

Hello all!

I have a question regarding batching in FlexSim. I'm attaching a screenshot of my model as well as the file name that I uploaded to FlexSim's share site. Essentially the model produces 4 types of items at different times, and I want the items to combine into 1, after the items leave the QA processors. I don't know if it would be better to use a combiner for this but I'm just trying to get some more insight here, and if there is any custom logic I would need to add to the model, whether it's a queue and batching or just using a combiner. Thank you!

Hey @Donald H, a combiner sounds like what you're looking for. Here's an example of one I made with your model.


Once items are finished at QA, they get sorted into queues based on type. The combiner will take in a flowitem to carry the items (i.e., the source at the top that spawns pallets into the combiner). Then it will take in a certain number of flowitems from each incoming port (1 from each in this case). Once the requirements have been met, it will process the pallet and send it off.

Hey Kavika,

Thank you for the answer! I do have one minor question regarding the combiner, there has to be a source as the first connection?

It doesn't have to be. The first port connection into a Combiner will assume that whatever comes in from there is the "pallet" or thing to be stacked on. You could have a bunch of totes somewhere in your model feeding into the combiners on a schedule if that works better. Here are the docs for the Combiner if you want to read more.

Thank you! I asked that question because when I first had it as such with a queue as the first connection the combiner would look weird and it would have 2 of my items with different types kind of stacked on top of eachother, if that makes sense? But now my model works as desired. Thank you so much Kavika!
