In this paper we study some models for dealing with Fuzzy Integer Linear Programming problems which have a certain lack of precision of a vague nature in their formulation. We present methods to solve them with either fuzzy constraints, or fuzzy numbers in the objective function or fuzzy numbers defining the set of constraints. These methods are based on the representation theorem and on fuzzy ...

The objective of this paper is to introduce a fuzzy linear programming problem with hexagonal fuzzy numbers. Here the parameters are hexagonal fuzzy numbers and Simplex method is used to arrive an optimal solution by a new method compared to the earlier existing method. This procedure is illustrated with numerical example. This will further help the decision makers to come out with a feasible a...
