摘要: In this paper we revise the context of "value uncertainty", as part an OLAP based environment. A new multidimensional-cubic model named if-cube is introduced which able to operate over data with imprecision either in facts or dimensional hierarchies. These query requirements led us introduce concept closure intuitionistic fuzzy set a universe that has hierarchical structure, H-IFS. We automatic recommendation analysis according concepts defined domain ontology order guide decision making aid
