Optimization using sequence version 22.0.1

Hello All,

I need to know how to use "sequence" to do the optimization. My model is similar to the one in the webinar (https://www.youtube.com/watch?v=8GBzt5B4Cu0 in min. 50:00), but they use permutation that is not included in version 22.0.1

Can you send me the webinar example update to version 22.0.1 or a similar example understand it

Thanks in advance!

Hey @Javiera VL, FlexSim has updated the Experimenter and has changed the way sequences are handled. Here you can find the documentation for how sequences are handled in FlexSim 22.0.

You can use a Sequence parameter. Here's an example model. Note that running the optimization requires an OptQuest license:

Thanks for the example, but in my model I need to change the order of arrival in the optimization, that is, from the table "GlobalTable1" the column 4

In "parameters" I indicate the following (Could my mistake be in the code OnSet?)

Because in the "Experimenter" I Indicate the following

"TimeProceso_op" is the End of simulation time

The optimization result are

But, if I run the simulation with Scenario 5, the result is different

Could you help me to solve this problem?

Thanks in advance!

Your code is setting column 1 of the table (tab[i][1]). It seems like it should set column 4 (tab[i][4]). Once you make that change, you can test changing the sequence manually, and resetting and running the model. You can verify that your global table is being changed correctly, and that your model uses the sequence in the global table correctly.
