Fuzzy Linear Fractional Set Covering Problem with Imprecise Costs

Abstract: Set covering problems are in great use these days, these problems are applied in many disciplines such as crew scheduling problems, location problems, testing of VLSI circuits, artificial intelligence etc. In this paper α-acceptable optimal solution is given for the fuzzy linear fractional set covering problem where fuzziness involved in the objective function. At first the fuzzy linear fractional problem is being converted in to crisp parametric linear fractional set covering problem then a linearization tech… Show more

“…The performance of the proposed approach is evaluated by some numerical examples taken from the literature or generated randomly. The obtained results show the superiority of the proposed approach over those of the literature such as the method of Gupta and Saxena [14]. Remainder of the paper is organized by five sections.…”

“…This problem has been solved in the literature very rarely. The only study of literature on this problem has been done by Gupta and Saxena [14]. Their method has some disadvantages such as 1) an initial feasible solution must be generated and the method starts with this solution by applying the gradient of the objective function, 2) the method is highly depended on the generated initial feasible solution, 3) for the case of problem instances with high number of variables, the method becomes inefficient.…”
