Abstract
In this paper we have introduced Heptagonal fuzzy numbers (HpFNs) which deals with the membership function for the set of seven numbers. Arithmetic operations such as addition, subtraction, multiplication and division of two HpFNs based on α- cuts method, Zadeh’s extension principle method and Co-ordinate method are discussed in detail. Membership functions are obtained for each method. Suitable examples and graphical illustrations are discussed for each method.
Keywords: Fuzzy set, Heptagonal fuzzy numbers (HpFNs), α- cuts.
