In this paper we define division operation of Triangular Intuitionistic Fuzzy number (TIFN) using α,β – cut and a scoring function to rank TIFNs. An accuracy function to defuzzify TIFN is also introduced. Based on this new approach, the solution of Intuitionistic Fuzzy Linear Programming is obtained. Finally, an illustrative example is given to verify the(More)
