So, I want to add a queuing system for each bus stop that the bus passes through, where the bus will stop first and pick up passengers from each queue at the stop. The bus's stopping time at each stop will be influenced by the number of passengers boarding or the duration of passenger boarding.
I have already created the simulation model, but I am still confused about integrating this queuing system into the model. Can anyone help? Thank you.

Hey @Fauzy Syaputra, here's a thought you could try.
You could add a queue next to each Network Node that acts as a "stop" (or "henti" as they're labeled in your model I think). You have a token circulating in your Process Flow that represents the bus. It has a label "token.bus" and a label "token.henti". Place a queue next to each bus stop and add a label, something like this:
With this label on the Network Node:
You can fill up the queue with a source or some other method. Then, in the Process Flow, you can use your token to get the number of people in the queue doing something like this:
int queueLength = token.henti.queue.subnodes.length; // save the value to an int if you're using this in code
Then you can use that queueLength in the bus wait time:
I used
2 * token.henti.queue.subnodes.length
as an example to say that it takes 2 seconds per person to board, so if there's 5 people to board the bus, it will take 2*5 = 10 seconds for the bus to stop and wait.
Finally, you'll need to empty the queue of people, so maybe you add a subflow to empty the queue while the bus waits.
can you please explain it in more in depth? i still don't understand it. where do I put int queueLength = token.henti.queue.subnodes.length; in processflow
Here's an example model that explains the concept.
