Many years ago I used a software program called Decide Right that allowed a
user to enter outcomes (buy a honda, or buy the chevy, or buy the ford), a
set of decision factors (costs the least, gets good gas mileage, easy to
maintain), a way to weigh the criteria (cost is more important than easy to
maintain) and then a way to rate the factors against the outcomes (honda is
"great" for gas but chevy is "good" for gas mileage, etc.),

Are there any add ons or excel products for doing this kind of thing in excel?

Thanks in advance
