This paper presents a method for solving posynomial geometric programming with fuzzy coefficients in a context of structural design model. We have been developed a two bar truss design model in fuzzy environment. By utilizing comparison of fuzzy numbers with different approaching method, the programming with fuzzy coefficients is reduced to the programming with constant coefficient. Then we can solve the two bar truss problem with fuzzy coefficients using a method to posynomial geometric programming. Finally, one comparative example is used to illustrate the advantage of the new method.
