This version of the simulator allows you to import utilities from a text-only file that you format in the .HBU format (described in our market simulator documentation). You can create these .HBU files with a combination of Excel and a text editor like Notepad or Wordpad. This allows you to bring utilities developed from any other program or means into our market simulator for analysis.
You could then stack all your respondents from your 7 projects into a single .HBU file. You can also add segmentation variables for use in the simulator.
