Can you set upper/lower limits within a distribution?

I am running an assembly line simulation and have approximate times for operator work at each station. I am instructed to use Lognormal distribution to run throughput and station/operator utilization. Is it possible to set upper and or lower limits to the distribution selections within a delay command? I am getting results at up to 3x the time per station that it should take on average and that skews my data to be inaccurate. Kind Regards,

You can use the Math.min() and Math.max() methods to bound the value returned from your distribution.

Here is a small example script you could test and tweak within a script window, then apply the same logic to where you're using your distribution:

double minValue = 8.5;
double maxValue = 10.8;
double distValue = lognormal2(0, 10, 0.2);
return Math.max(minValue, Math.min(maxValue, distValue));
