How to ensure both processors have similar average time in content?

Previously, Mr. Tanner has answered my queries about the best model to simulate flow both ways here.

https://answers.flexsim.com/questions/79379/best-model-to-simulate-flow-of-items-2-ways-simult.html

However, processor 1 is the "main" processor and as run time increases, the average time to process the content by processor 1 is much larger than processor 2. Is there a way to ensure both processors would have similar average times to process the contents given by the source?

The model I'm trying to create is as with the diagram below and if some processor are faster than others it may cause discrepancies in the data.

Here is the simplified model Tanner has suggested.

Hi @JIANYUAN, HALLEY L,

I'm sure you've seen my response to this question on your other post, but one thing that might be useful to you in your model is the use of a Round Robin or other logic that alternates the direction that tokens are sent each run. I've updated the example model provided to reflect this. It alternates opening Processor 1 first and Processor 2 first. See if this helps average out the flow like you're hoping. It might not be the most robust way to accomplish your modeling scenario, but it might help give you some tools to use for building your model. You might even consider using all Process Flow rather than a mix with the 3D objects. I'm glad you've looked at the tutorials - it will help you to use the concepts taught there.

The first Round Robin is found in the Source, which sends to port based on Round Robin logic.

The second Round Robin is found in the Decide activity, which decides which input port to open up first.

Note that these work independently of each other.
