Anylogic - Automate multiple runs of a simulation model in Anylogic

Question

I have a simulation model written in Anylogic. The output of the simulation is automatically exported to an excel file. I need to run the simulation about 20 times for each of the 10 scenarios and it each run takes about 30 minutes for each run.

How can I automate this process? Also, I want to be able to pass a few arguments to the model for each run.

What would you like to automate? The output writing process? Or having 20 runs? — Yashar Ahmadov, Jan 07 '22 at 19:28
Thanks for the reply. I would like to automate 20 runs and be able to pass a few arguments to the model for each run. — Prabin Lamichhane, Jan 07 '22 at 19:39

Use the Parameters Variation experiment.

You can access any run number on Main startup with the code int a=getEngine().getRunCount();. You can prepare the inputs beforehand in an Excel and pass the parameters based on the count number.

You can write the outputs separately for each run. Use the following code as an inspiration where I write myVariable at the end of each run to csv files called output0.csv, ouput1.csv, etc. (This happens in Main -> On Destroy.

int a=getEngine().getRunCount();

String filename="output"+a+".csv";

try
{
 FileOutputStream fos = new FileOutputStream(filename);
 PrintStream p = new PrintStream(fos);
 
 for (int i=0; i<100;i++){
    for(int j=0;j<10;j++){
        p.println(myVariable.output[i][j]);}} // outputs tab delimited values
}
catch (Exception e)
{
 traceln("Could not write to file.");
}

Thanks @Yashar. Parameter variation solves the problem. – Prabin Lamichhane Jan 08 '22 at 16:54 — Prabin Lamichhane, Jan 08 '22 at 16:54
