We define concentration, dilation and normalization of intuitionistic fuzzy
sets. These definitions will be useful while dealing with various linguist
ic hedges like "very", "more or less", "highly", "very very" etc, involved
in the problems under intuitionistic fuzzy environment. We also prove some
propositions and present some examples in this context. (C) 2000 Elsevier S
