Sum to One Principle

I'm working on a fuzzy decision making system which uses linguistic
variables represented by fuzzy numbers. I've heard somewhere that the
individual degree of membership of overlapping linguistic variables
should sum to a total membership value of one. Does anyone have any
references to this or any observations on it as an idea, particularly on
how it would apply to at hedges?
