Abstract: In this paper sequencing problem is solved with triangular intuitionistic fuzzy numbers. Processing times taken as intuitionistic fuzzy numbers are defuzzified with defined ranking and optimal sequence is obtained. In the last total elapsed time and idle time for each machine is also calculated. Numerical example is given to clear the concept.

Keywords: Intuitionistic fuzzy number, Triangular intuitionistic fuzzy number, optimal sequence, ranking of triangular intuitionistic fuzzy number.
