Fuzzy vs. Minmax Weighted Multiobjective Linear Programming Illustrative Comparisons
Authors:Frederick K. Martinson
Abstract:This paper compares two approaches to the solution of weighted multiobjective linear programming problems: the fuzzy linear programming method and the minmax distance metric. The two models produce an identical solution for equally weighted objectives, but the solutions differ when the objectives are unequally weighted. This is due to the underlying meaning of the weights attached to each solution method. The paper illustrates the graphical meaning of the weights and the implications to the decision maker.
Keywords:Decision Support Systems  Fuzzy Sets  Linear Programming  and Mathematical Programming
