Abstract

In this paper, we introduce and investigate the concept of c-fuzzy numbers. We extend the algebraic operations on c-fuzzy numbers, and specially study the properties of these operations on LR type c-fuzzy numbers. In addition, a dual of extension principle is introduced. It is shown that the algebraic operations with c-fuzzy numbers have a representation based on the dual of extension principle.
