摘要：In previous work, authors have proposed two new aggregation operators for a class of LR fuzzy numbers known as triangular fuzzy numbers (TFNs) in which the L- and R- apex angles of the piecewise continuous linear membership function of the composite or resultant or aggregate TFN are the arithmetic means [1] and the geometric means [2] of the L- and R- apex angles of the individual TFNs. In this paper the concept of an aggregation operator for triangular fuzzy numbers based on the arithmetic means of the corresponding L- and R- apex angles is extended for a class of Interval Fuzzy Numbers known as Trapezoidal Fuzzy Numbers (TrFNs). The left and right side angles have been treated independently as was done for the L- and R- apex angles in the case of LR TFNs. Computation of the aggregate is demonstrated with a numerical example. Corresponding arithmetic and geometric aggregates have also been computed
