Run replicates using FlexSimPy

Hi

I'm trying to run replications of a scenario using the FlexSimPy's runToTime() method. However, I haven't found a way to run the scenario with different random streams. Therefore, all results are deterministic. Is there a way to run replications with FlexSimPy?

These are the Python commands I'm using:

import os
import FlexSimPy as fp
 
scriptPath = os.path.dirname(os.path.realpath(__file__))
programDir = scriptPath + "\\..\\..\\..\\..\\program\\"
 
# Launch FlexSim
controller = fp.launch(evaluationLicense=True, showGUI=False, programDir=programDir)
 
# Open model
controller.open(scriptPath + "\\MeuModelo.fsm")
 
# Set parameter
controller.setParameter("NumOperators", 1)
 
# Reset and run
controller.reset()
controller.runToTime(1440)
 
# Get performance measure
print(controller.getPerformanceMeasure("Output"))

Thanks!

One possibility would be to use a Model Parameter. Set its type to Pass-Through, and point it at the node MODEL:/Tools/randomrepeatrep. If that node isn't present, you can just add it, and give it number data.

Then, in your python code, call setParameter() to set that parameter, and then reset the model.

Hi,

I'm using the same code as Afonso, but when I pass evaluationLicense=False, it returns the error "lc_flexinit failed: 1". I'm using an Educational License, but I already tried it using an Enterprise License and got the same error.

How can I fix it?

Thanks.
