Solving fully fuzzy linear programming problem by the ranking function. (English) Zbl 1169.90488
Summary: The modeling and solving the optimization problem is one of the most important daily problem. By notation the nature of data in practice which are imprecise, fully fuzzy linear programming problem (FFLP) is a power full tool to modeling the practical optimization problem. In This paper after introducing FFLP, a new method to solve it is proposed. a linear ranking function for defuzzifying the FFLP is used. Equivalency between two problems is proved by some theorems.
