In this paper, the authors introduce the semantics of the Intuitionistic fuzzy cubic representation in contrast to the basic multidimensional-cubic structures. In this paper, they present their approach for extending the OLAP (OnLine Analytical Processing) model to include treatment of value uncertainty as part of a multidimensional model inhabited by flexible data and non-rigid hierarchical structures of organization. A new multidimensional-cubic model named as the IF-Cube is introduced which is able to operate over data with imprecision either in the facts or in the dimensional hierarchies.
