Referring to a global variable in the Experimenter 2021

Hi,

I have created two global variables (Percentage & Percentage2) to use in the decide activity. I want to change these percentages in different scenarios in Experimenter. So, I created two parameters referring to the Data node under the Tree node where these two variables are. But for some reason, the model and the scenario chart do not work correctly. Could you let me know where I went wrong?

SimpleModel_Test_2.fsm

Software Version:

FlexSim 21.1.2

experimenter flexsim 21.1.2 parameters global variables

simplemodel-test-2.fsm (122.5 KiB)

if you refer to them in different scenarios and you think they can be changed as an interface between those scenario, then your expectation is wrong. Each scenario is a standalone copy of your model. There aren’t any connections while scenarios are running.

@Jörg Vogel Then how I can change the percentage of a decide activity in different scenarios? Is there a way to do this? I was looking at this post and think I have the same problem/question: https://answers.flexsim.com/questions/28857/experimenter-and-global-variables.html

You set the value statically different in every scenario. You are not allowed to change values depending on a result of a different scenario while you running an experiment. You can only run an experiment, evaluate the results, set different value and start an experiment manually again. I am not aware of a script that executes a “run” experiment command from an running model within FlexSim. I can think only of a batch process on Windows system to start FlexSim and run automatically a set of experiments by evaluating a text file written upon last closed session of FlexSim.

I tried to get acces to a node at a global variable. It was the Type. Unfortunately the experimenter doesn't change the Data node of the global variable, even if I describe the path relative from the Type node. I could only set a global variable value by a label On Reset. This label value can I change by an experiment. set_global_variable_by_label_for_experiment.fsm
