Abstract

In practice, there are many problems in which all decision parameters are fuzzy numbers, and such problems are usually solved by either possibilistic programming or multiobjective programming methods. Unfortunately, all these methods have shortcomings. In this note, using the concept of comparison of fuzzy numbers, we introduce a very e
ective method for solving these problems. Then we propose a new method for solving linear programming problems with fuzzy variables. c
