To improve the method of Dong and Wong (Fuzzy Sets and Systems 21 (1987) 183–199) for obtaining the fuzzy weighted average, a steepest descent/ascent method was proposed by Liou and Wang (Fuzzy Sets and Systems 49 (1992) 307–315). In this paper, we propose to replace the steepest descent/ascent method by linear programming, which is a much more powerful approach for large problems. The reduction of the original nonlinear programming problem into a linear one is achieved by the use of the Charnes and Cooper's linear transformation method. The example used by Dong and Wong is again used to illustrate the approach.
