Variant change simulation

Hello everyone,

I am doing a simulation of a production line that can produce two diffrent variants (F_F and F_M) of a product with two diffrent process flows.

I created a GUI to make a variant change but didn't know how to implement the change in the "process flow".

In the GUI I added two buttons one to select F_F and one to select F_M.

Can I get some help on that?

Thank you.

You need to store a value somewhere that you can access in the decide activity and thus determine the product type. This can be many things: A label defined on some object or the process flow itself, a global variable, a cell in a global table, ...

As an example I added a label ("Production") to the process flow and changed your GUI buttons to set this to either 1 (F_F) or 2 (F_M). The decide is send the token to the connector with the respective rank.

Thank you for your response.

But when the simulation is running, pressing the GUI buttons will do nothing. The values will only change when I reset and rerun the simulation again. This is not my goal.

My goal is to be able to switch the variants I want to produce while the simulation is still running.

For example: I run the simulation to start the production of the variant F_F, then whenever I want I can press on the F_M button to switch the production to the F_M variant without restarting the simulation again.

Then you can implement the decide activity after each production run to see if the product type should change.
