G. UTHRA, K. THANGAVELU, B. AMUTHA*

Abstract


This paper introduces Symmetric Octagonal Intuitionistic Fuzzy Number (SOIFN) and its arithmetic operations. The arithmetic operations addition, subtraction, scalar multiplication and additive inverse are performed using (α, β) cuts.  An example illustrates the proposed arithmetic operations of Symmetric Octagonal Intuitionistic Fuzzy Numbers(SOIFN).   


Keywords


Fuzzy set, Intuitionistic Fuzzy Set, Octagonal Intuitionistic Fuzzy Number (OIFN), Symmetric Octagonal Intuitionistic Fuzzy Number (SOIFN).
