Need help with Batch Process

[ FlexSim 7.7.4 ]

I am trying to figure out how to create a batch process where 15% of the time , the batch goes to Port 2 and the rest of the time goes to Port 1. By doing 'By Percentage' it only moves part of the batch to Port 2 and not the whole batch. Can you help?

Maybe you could try this. It`s not elegant but it works:

Put a numlabel on the queue that produces the batch and call it e.g. "path"

On the OnEndCollection Trigger you just write this:

// Produce a uniform distributed random number between 0 an 100 
double randomNumber = uniform(0,100);

// Write the path for the batch accoring to the randomnumber you got
if (randomNumber < 15) setlabel(current,"path",1);
else if (randomNumber >= 15) setlabel(current,"path",2);

This sends the batch in 15% of the cases to port 1 and in 85% to port 2.

To make this work you just use the label at the the Send To Port trigger

Actually you can replace your whole code with

setlabel(current, "path", bernoulli(15, 1, 2));

Oh yes you`re absolutely right. Thanks! The more you know 🙂

Thanks guys. This worked in my simulation. It saved me some time trying to figure this one out.
