Solving fuzzy linear fractional set covering problem by a goal programming based solution approach

<p style='text-indent:20px;'>In this paper, a fuzzy linear fractional set covering problem is solved. The non-linearity of the objective function as well its fuzziness make it difficult and complex to be solved effectively. To overcome these difficulties, using concepts theory component-wise optimization, converted crisp multi-objective non-linear problem. In order tackle obtained problem, goal programming based solution approach proposed for Pareto-optimal solution. linearized by applying some linearization techniques in procedure approach. also initial As advantage, applies no ranking numbers stage considers preferences from decision maker. computational experiments provided examples literature show superiority over existing approaches literature.</p>
