Performance measure works on dashboard but is always 0 on experimenter/optimizer

Hi,

I created 5 performace measures, each of it references to the dashboard stats, when I run the simulation I can see how these measures update, but when I use the experimenter or when I try to optimize them (my objective is to minimize these measures) they always have a value of 0. I am attaching screenshots and the model.

Thanks!

Are your results and performance measurements parameter driven?

Yes, I have 2 parameters (the number of tables and the number of workers), the idea is that I want to minimize both parameters as well as the performance measuers

The issue is in your parameters. You are using the Delete and Copy Objects option, which works fine in some models, but is incompatible with the People module.

In order to create the correct kind of parameter, you need to use the Sampler on the Reference field to sample the the Staff group (or the TableAndChairs group) and choose the "Set Number in People Group" option.

Once you make that change, it should work just fine.

Also, however, I noticed something strange. You had a folder called "StatisticCollectors" in your Tools folder. I moved the stats collectors in that folder to the proper "StatisticsCollectors" folder. I also made sure that the stats collectors had unique names.
