Measuring the efficiency of production units by AHP models with fuzzy preference

The aim of this paper deals with models and methods for the evaluation of efficiency of production units. The Analytical Hierarchy process deterministic model deals with deterministic preference. But it’s observed that decision makers can not decide about the evaluation of problems preference related to them. That is why for removing this problem we represent fuzzy preference. This paper discusses the possibility of using AHP model with fuzzy scores. For evaluating and categorizing the efficient units.
