@Jeng SY The simple reason is you create an odd number of flow items. When an item finishes processing at Processor 2, it creates flow items at Processor 5 and Processor 3, and then moves the item in Processor 2 to Processor 3. If you run this cycle twice, it will allow everything to be combined. You run it three times, so you end up with an odd number of items, and they cannot all be combined.

As far as the rest of your question, I am having a little trouble understanding you. Are you asking how can you let the customer in Processor1 just get one item from the combiner?

@Braydn T Thank you very much, you answer my first question.

My second question is as you thinking, I want the customer in Processor 1 can take one item from combiner.

And what should I do next?

Thank you!!

Best Regards.

A Combiner can't execute a different process on the same item. In other words, you can't have the Combiner not combine a certain item type when it has been doing it the whole model run. I would put a queue before the Combiner, and set a trigger to release 2 items from the queue into the combiner when the quantity reaches 2, and have it timeout after a certain amount of time and go straight to the next step in your process.

@Braydn T I modify my model, but I still cannot understand what you said "have it timeout after a cerain amount of time and go straight to the next step", I don't know what can I do, just what you said, let the customer take one item and go to the next step.

Could you help me to modify my model to answer this question?

Thank you very much.
