en تخصصي Special پژوهشي Research <p>In this paper we consider a global optimization approach for solving fuzzy fractional posynomial geometric programming problems. The problem of concern involves positive trapezoidal fuzzy numbers in the objective function. For obtaining an optimal solution, Dinkelbach&rsquo;s algorithm which achieves the optimal solution of the optimization problem by means of solving a sequence of subproblems is extended to the proposed problem. In addition, An illustrative example is included to demonstrate the correctness of the proposed solution algorithm.</p> Trapezoidal fuzzy number, Fractional programming, Global optimization, Posynomial geometric programming, Parametric approach. 27 38 http://ijorlu.lahijan.iau.ir/browse.php?a_code=A-10-1-175&slc_lang=en&sid=1 F.
