This paper represents the basic components of the base architecture of an interval type 2 fuzzy logic system. There is presented the inference engine realized by these to components in case of crisp input and output of interval type 2 fuzzy logic system, on the basis of use of mathematics for type 1 fuzzy sets. There is offered the base architecture of decision support system on the basis of use of the basic components of the architecture and the inference engine of an interval type 2 fuzzy logic system within the limits of research of intellectual information technology.
