Parameters with global table

Hello,

I want to use the experimenter to simulate different scenarios of the next model. I have the next parameters which I want to change them in the experimenter: The arrival time of the items, the quantity and the process time. I have created a global table for each parameter and in each row I have set the data of each scenario. I have created also the parameters in the toolbox but I don't know how to set the global table in the value of each parameter in the parameter section of the toolbox. I have attached the model, thank you. Example.fsm

FlexSim 22.1.4

You don't need the global tables - you can enter the values into the experimenter job definition:

Then either use the OnSet of the parameter to write the value to the reference object's property*:

Or have the object read the property:

Note that the stream expression for process time will need to change for the latter from getstream(ownerobject(c)) to getstream(reference)


*Also note that you will need to edit the code of the OnSet to set the ProcessTime since it was omitted from the version you are using - it doesn't appear as a dropdown option.

Thank you very much but, is there a way to do it with global tables? Because I have to apply it to a more complicated model and I would like to do it with global tables.

I would like to create parameters in order to change the global table variables.

You can use the Parameter onSet to change table values either referring to the cell in the OnSet code or having the cell as a reference and just using reference.value=newValue; in the OnSet.

I can't do it. Automatically the values of the global table are set to 1 and the following error appears.Example.fsm

And then also I have thought to use the experimenter to change these values.

You haven't any values to set - the parameter table is blank.

Also - you've set the type to expression so the numbers will get written as strings to the table cells - is that what you want?
