A Mathematical Model for Fuzzy p-Median Problem with Fuzzy Weights and Variables

الملخص EN

We investigate the p-median problem with fuzzy variables and weights of vertices.

The fuzzy equalities and inequalities transform to crisp cases by using some technique used in fuzzy linear programming.

We show that the fuzzy objective function also can be replaced by crisp functions.

Therefore an auxiliary linear programming model is obtained for the fuzzy p-median problem.

The results are compared with two previously proposed methods.
