Non-Linear Arithmetic Operations on Interval Valued Trapezoidal Fuzzy Numbers

Abstract

Fuzzy numbers have been introduced by Zadeh in order to deal with imprecise numerical quantities in a practical way. In this paper, some types of interval valued trapezoidal fuzzy numbers (IVTrFNs) and some non-linear arithmetic operations on interval valued trapezoidal fuzzy numbers have been proposed. Also relevant numerical illustrations are included to justify the above said notions.
