One of the most interesting models of the linear programming is the flexible linear programming problem. It is shown that by using a suitable membership function for their constraints, we can obtain an equivalent Fuzzy Variable Linear Programming (FVLP) problem. Some methods have been developed...

In this paper we provide a two-stage group decision-making procedure for ranking a great number of alternatives. Since individuals usually have incon-sistencies in the pairwise comparison of alternatives, we allow agents to assess alternatives one by one using linguistic labels. This information...
