## How can I specify random values as delaytime for waypoints?

I have created a simulation in which the onward journey of the AGVs is delayed at the waypoints. Two types of waypoints are to be distinguished. With one group (Montage) there is a fixed delay. In the other (verzögerte Montage), the delaytime should vary randomly in a certain area. I tried to do this with a normal function (normal(5.3,0,2)). However, the result is the same as without the function, as if I had entered a fixed value. Also, the use of the Bernoulli function (bernoulli(33,5.5,5) has always brought the same result, regardless of the given probabilitywithDelay.fsm.

How can I specify variable random values in a certain range as a delay?

I can't seem to replicate the issue. Different distribution produce varying results, all longer than a fixed waiting time (because longer waiting times propagate down the chain of agvs due to control point allocation).

This might sound obvious, but did you remember to hit "Apply" between changing the delay time and running the model again? I definitely sometimes forget to do that.

Probably you have still activated repeat random streams. Turn it off.

Try 'normal' with one 'l' - recognized keywords should be shown in blue.

Sorry, I had just changed it for the screenshot and mistyped. But as you can see from the pictures, it doesn't make a difference even spelled correctly

Do you have any other suggestions? As you can see from my comment, time does not change even with correct keywords.
