I want to generate random numbers in my model. Every time I run the macro my cells range "G8:H34" have to fill in with different random numbers that should be integers from 0 to 2.

I have to generate those numbers in VBA, because I need to use them in order to optimize a model for a minimal costs and use loop after that to find the best combination that minimizes the cost.

  • So you are allowed to use =rand() or =randbetween(x,y) instead of VBA?

You don't need VBA for this. Just use RANDARRAY([rows], [columns], [min], [max], [whole_number])

In G8 put this

=RANDARRAY(27, 2, 0, 2, TRUE)

and random numbers will be filled in the range G8:H34 automatically

Consider:

Sub qwerty()
    Dim r As Range
    Set r = Range("G8:H34")
    With r
        .Formula = "=randbetween(0,2)"
        .Copy
        .PasteSpecial (xlPasteValues)
    End With
End Sub
