In this paper, several kinds of non-classical fuzzy problems–direction fuzzy problems are presented, which classical fuzzy sets do not deal with well. In order to solve them, direction fuzzy sets are introduced by breaking through the limitations of the definitions of classical fuzzy sets. And the union and intersection of direction fuzzy sets are discussed. Especially, an application example (Escape Model) is dug up to show the significance of the direction fuzzy set theory.
