same result for each run of simulation.

Dear All,

in the attached model, for each run of the simulation I am getting the same result every time. however I set the task executer loading time random distribution so I expect to get different travel time each time I run the simulation Also I turn off the check point of "Repeat Random Stream".

@MPeyman, in case you use an express licensed version this is a feature of restriction.

Dear @Joerg Vogel , I am using "FlexSim Educational" So with this version I'm not able to get different result. Recently I updated it. and last year by turning off this feature I could get different result.

Then such a behavior can be a result, if you have a set of parameters that cause a static behavior in your model.

Your operator streams are 102 and 103 but in your script you initialize stream 1 only to your seed value.

dear @Jason Lightfoot, I investigated and see that the seed is not a problem here I attached my modified model. I remove the experiment and the custom code in that. Instead as it depicted in the picture in the last part i defined the custom code that when the list is get empty stop and save the result in stat.csv. But its only capture the one operator and the other one is always zero so I assume that I need some "If" condition in order to capture both operator and I don't know How should I call it to give me for the both operator.original_Zones_Connceted.fsm

You're calling stop as soon as the first token exits - remove that and let it run to completion naturally (no more events).

yes but if I remove this script then anywhere that I tried till now doesn't give me the right answer so I would create a logic like when the process of the operator process get finished then save it to file and end the program and send the done to python. something like this:
