IF / AND / OR statements

This is the Excel version of the formula I am using which is not working:

=IF(OR(V3>19958*0.85,AND(Y3="20FT_COFC",AF3>33*0.85),AND(Y3="40FT_COFC",AF3>67*0.85),AND(Y3="40FT_HC",AF3>76*0.85)),"","Not ")&"Optimized"

 Attached/Below is an excerpt of the data set:

 Basically this is what I am trying to do:

Argument 1
If the column V (Total Weight) is greater than 85% of 19958, I want the column to indicate "Optimized".

Argument 2
If Column Y (Equipment Type) = 20FT_COFC and column AF is greater than 85% of 33, I want the column to indicate "Optimized"

Argument 3
If Column Y (Equipment Type) = 40FT_COFC and column AF is greater than 85% of 67, I want the column to indicate "Optimized"

Argument 4
If Column Y (Equipment Type) = 40FT_HC and column AF is greater than 85% of 76, I want the column to indicate "Optimized"

If none of those 4 arguments are true, then I want the column to indicate "Not Optimized"

I hope that makes sense. Thanks !
