The theory of ordered intuitionistic fuzzy sets is well suited to dealing with vagueness. In this paper, we first define ordered positive ideal intuitionistic fuzzy sets, ordered negative ideal intuitionistic fuzzy sets and establish some results on them. Then, we define similarity measures between ordered ideal intuitionistic fuzzy sets and apply these similarity measures to multiple attribute decision making (MADM) model under ordered ideal intuitionistic fuzzy environment.
