Now a day’s uncertainty is a common thing in science and technology. It is undesirable also. Based on alternative view, it should be avoided by all possible means. Based on modern view uncertainty is considered essential to science and technology, it is not only the unavoidable plague but also it has impacted a great utility. Fuzzy set theory mainly developed based on inexactness, vagueness, relativity etc. fuzzy set may be used in mathematical modelling in every scientific discipline. It can also use for improving the generality of analytical solution. It has many uses in various streams like -operation research, control theory differential equations, fuzzy system reliability, optimization and management sciences etc. In this paper we first describe Trapezoidal intuitionistic Type 2 fuzzy number(TrIT2FN) with arithmetic operations and solve an assignment problem using Hungarian method for Trapezoidal intuitionistic Type 2 fuzzy number (TrIT2FN).
