摘要：In recent work authors have proposed four new aggregation operators based on the arithmetic and geometric means of the L- and R- or right side and left side apex angles for triangular and trapezoidal fuzzy numbers respectively. In this paper authors propose a new aggregation operator for TFNs in which the L- and R- membership function lines of the aggregate TFN have slopes which are the arithmetic means of the corresponding L- and R- slopes of the individual TFNs The Land R- membership function lines are treated independently. Computation of the aggregate is demonstrated with a numerical example. Corresponding arithmetic and geometric aggregates as well as results from the recent work of the authors on TFN aggregates have also been computedldin
