Arithmetic of Triangular Fuzzy Variable from Credibility Theory

In this article, it has been shown that the credibility distribution of triangular fuzzy variable leads us to find a very simple alternative method of finding the membership function for functions of triangular fuzzy variables. This concept of credibility theory also leads us in finding an alternative method of computing basic arithmetic operations of triangular fuzzy variables and generalised membership function for the root of triangular fuzzy variable. The method has been demonstrated with the help of some examples.
